World Wide Web Proxies – Web Proxy List

In the earliest days of the web in 1990, web proxy servers were usually referred to as gateways.  In fact the very first web gateway was created at CERN by the original WWW team , headed by Tim Berners-Lee.

Gateways are effectively devices which are used to forward packets between different networks. These devices can vary in complexity from simple pass through devices to complex system which are able to understand and convert different protocols.   It was in 1993 that the name Web Proxy Server was chosen as a standard term to describe the different types of Web gateways.

Web Proxy Server

These can be further classified into two distinct categories:

Proxy Server – internet/firewall gateways which act in response to client/PC requests.

Information Gateway – gateways which act in response to server requests.

However these are quite broad specification and below you will find some details of the key properties of the proxy servers and associated gateways.  Remember that these classifications can be affected by any application software which is installed on the proxies so they are not necessarily just the simple servers you find on web proxy lists – which are normally just basic Glype installations.   Particularly you may find that destinations and transparency may sometimes  be modified.

Proxy Server Properties

These are the general properties which can be applied to any specific proxy server, there are variations which will affect these.

Transparency: these proxies do not modify the data passing through them. They will perform any filtering specified by rules but this will not affect the end result. The connection will be the same if it was direct or through the proxy server.

Control: the client will determine whether it is uses the proxy or not.  This is typically controlled on the client by specifying the address of the proxy or through client based software.

Destination: the final destination of any request is not affected by any intermediate proxy.  In fact a client or user will often be completely unaware of the existence of the proxy.

Proxies can provide all sorts of features some of which might affect these properties.   They can be used to provide specific access controls, filtering, logging and even simply to speed up access to remote web resources through caching features.

It is in corporate environments that the transparency properties of proxies has usually been modified.  Frequently these firewall proxy servers will sit in the DMZ (Demilitarized Zone) and control both inbound and outbound traffic.  They will accept network requests from clients and forward them out to the internet if approved, then relay the replies back to the clients.   Most of these will also operate caching services to ensure that duplicate requests don’t generate more network traffic and bandwidth charges.  This is especially important for servers with high utilization such as a video proxy or firewall.

The other advantage of the dual role proxies is that it can act as a single entry point for internet access.   This means that all requests can be logged and monitored allowing an element of control to web access through the company infrastructure.  It also allows replies to be monitored for harmful code such as malware and viruses, this is an important extra layer of security to protect the internal network.

Using Proxies to Maximize IP Addresses

The use of proxies has changed greatly since I started in IT about 25 years ago.  Then most company networks in medium sized companies usually managed with a single proxy running something very simple or annoying like Microsoft ISA server.  Of course most corporate networks still use proxies, however now they’re needed to cope with internet access on the desktop and adding an extra layer of Anti-virus protection to the client PCs.

However it’s outside the world of IT support that I’ve seen proxies change the most. Nowadays you’ll see all sorts of people using them, for all sort of reasons ranging from privacy to online businesses.  You’ll also see big corporations and marketing companies investing in proxies in order to analyse and support their online businesses.

One of the problems of the internet as far as international companies goes is that it’s sometimes difficult to assess what your advertising or web presence is like in another country.  A large company will often spend to create a presence in lots of different countries but it’s difficult to assess how those efforts are working sometimes.   For example a US company will find it difficult to assess how they look in South Africa if they’re sitting in an office in New York.

It’s because so many components of the internet are becoming localized.  Search engines and advertising sites will tailor their results based on the location of the user and it’s difficult to bypass this effectively. The only certain way is to use an IP address in your target country, however to do this you need someway to deliver that experience to your computer.

Also IP addresses are expensive and often abused so decent residential based IP addresses are even more costly and difficult to obtain.   To accomplish lots of task especially marketing and research you need an awful lot of them too.  Fortunately there are now solutions which offer the facility to gain access to lots of these addresses without huge costs previously involved.

The solution to this issue is to stop the actual assignment of individual addresses to specific proxy servers.  Instead a concept has been developed called residential backconnect proxies, which focus on providing address pools to proxies which can be switched easily.   The IP addresses are stored and allocated through a central database which assigns to individual connection request either randomly or sequentially.

So when a request comes from the client to visit a certain website, the proxy is then allocated an IP address from it’s pool.  It’s at this point the type and location of the IP address can be determined, so a French address could be assigned if the client requested a French resource for instance.  Also other important factors can be assigned – perhaps a residential address or one allocated for use on a specific social platform.  This means that many people can gain access to a huge pool of IP addresses without concurrent connections.  This is important especially with social networks, where many concurrent connections from individual IP addresses can raise red flags.

It also ensures that the expensive addresses like residential ones are not abused or end up getting blocked or banned.  Having central control over which addresses are used is much more efficient than selling access to them individually to different people.  Also being able to maintain a list of residential addresses and a list of Netflix addresses means that the resources are not misused by mistake.

 

Can We Trust Dynamic Optimization

Dynamic Compiling, Dynamic Optimization and Code Morphing are some of the buzz words you’ll find used often in programming circles especially online.  Yet for anyone who’s released a piece of code or an update that’s gone wrong, they are phrases that can make you very nervous.   So what do these phrases actually mean and what is their impact on today’s technology?

Dynamic Compiling and Dynamic Optimization are the most common names for it. “Code Morphing”, the most hip term so far, was coined by David Ditzel of Transmeta. The Tao Group prefers the name Dynamic Binding. However, there are still people who use another name altogether: Binary Translation (because translation is such an essential aspect of the technology). But don’t worry. I will use the nice simple abbreviation CF (Code on the Fly) to prevent ourselves from getting all tongue-twisted.

Yet our technology is everywhere now and in some senses it’s impossible to keep up with all the improvements and updates that are necessary.   Even applying security patches to code can be a huge job and many organisations struggle to cope with even this basic requirements.  Imagine the thousands of servers and proxies in most corporate network which need constant updates without even considering normal efficiency based code changes.  This becomes even more important when you have critical roles for specific servers although the volume is obviously reduced.  The ‘point of entry’ server for large backconnect databases you find for people trying to access bulk shared proxies such as these potentially affect thousands of individual connections.

Like most technologies, CF is really a simple concept disguised by big fancy words. An example is the best way of understanding what it’s all about.

We will use Java as our example because it is so popular these days. Java programs are really “pretend-programs” written for a “pretend-computer” called the Java Virtual Machine (JVM). To run a Java program, a “real-program” is needed that pretends to be the JVM by emulating it. Now emulation is very slow. So to speed things up a Just-In-Time (JIT) compiler is used. The JIT compiler converts the Java program into a “real-program” by generating code for the “real-computer” while the JVM program is running (or in other words, on the fly). JIT compilers are faster than emulators because they execute Java programs more directly than the emulator’s slow interpretive layer. A JIT compiler is an example of Dynamic Compiling. Pretty straight forward, uh? Traditional compilers don’t fall into the CF category because they generate code before the software is delivered.

Even microprocessors use Dynamic Compiling. Instruction level parallelism (ILP) (also known as Out-Of-Order [OOO] Execution) is attained by re-arranging instructions, which is essentially a form of Dynamic Compiling. The entire Pentium line translates the horribly complex x86 opcodes into the micro-ops actually understood by their underlying RISC engines. Similarly, Transmeta’s Crusoe and the Elbrus 2000 translate x86 and IA-64 instructions into those actually used by their respective VLIW processors.

There is a whole spectrum of opportunities available for optimization. Static optimization at compile time is one point on this spectrum. Dynamic optimization at runtime is another. Dynamic Optimization is a more advanced form of CF. It aims to improve the performance of (already) native programs. This task is done by determining the hottest bits of code and laying them out next to each other. Since the code is no longer spread out all over memory, there is less trashing in the instruction cache. These straight lines of code are then optimized using traditional techniques such as loop unrolling, constant propagation and dead code elimination.

They are particularly useful in the role of e-commerce servers where dynamic updates mean that downtime is minimized.  Many of these sites costs lots of money to update particularly when you consider the volumes of sales involved.  However the upgrades are essential because they are frequently the target of abuse, either criminal or people trying to abuse the systems.  Once example is where people use so called ‘sneaker proxies’, read about them here, to bypass restrictions and create resell markets.

A technique unique to Dynamic Optimization is the removal of each method’s entry and exit code, thus effectively inlining the entire function on the fly. These optimizations address the inability of compilers to optimize across method boundaries, virtual function calls, DLLs and components. Compilers can not see past these boundaries because they don’t know which calls will be made at runtime. They also don’t know what the user input or targets of dynamic linking will be. Thus Dynamic Optimization fills a niche that compilers cannot.

Need Lot’s of Proxies? Here’s a Solution

For many online activities particularly those crucial money making operations, scale is important. Although making a few dollars from reselling a pair of in demand sneakers is great, it’s not going to pay all your bills. The key to many methods to making money on the internet is to increase volume and you can’t do that with a single digital identity.

Take for example a method using an social media site like Instagram. You may have found that you can advertise your product and promote it using pictures and posts, making a few sales each time you do so. Unfortunately when you try and do this multiple times you’re going to get filtered, blocked or even banned. Most of these websites try and discourage commercial activity unless your paying them directly to advertise of course. So the secret is to spread out the activities using multiple accounts and to do this you need multiple identities.

If you’ve ever tried to open a bunch of social media accounts from the same location, you’ll know it doesn’t work. The first one or two might but then your accounts will get rejected. The same if you try posting to different accounts from the same address, they’ll get flagged and blacklisted at a minimum or more likely deleted completely. If you’ve ever see the pain of someone losing a valuable and popular Instagram account, you’ll know how traumatic that can be.

The solution to running multiple accounts, posting multiple ads or basically to scale anything up is to run multiple identities. Proxies used to be the normal solution to this problem and to some extent they still are. However the complexities are growing and the days of just grabbing a free online proxy to hide your identity are long gone at least as far as most modern websites go. There are many problems with this method but the most blatant one is that you won;t be the only one doing this.

For example if you search online and find a free proxy which you want to use for posting your Instagram profile, there will almost certainly be loads of people doing this already. To access any website while possibly hundreds of people are doing this concurrently is very bad news for those profiles. The profiles will at the very minimum be flagged for suspicious activity and could very well be deleted very soon after.

The same goes for accessing any sort of website, multiple connections from a single IP address is easy to detect and will always mean trouble. Of course the risk is there with paid proxies too, the problem is that IP addresses are expensive and it costs a lot to have them dedicated primarily to you. A dedicated proxy server with reserved IP addresses is great but it comes at a cost. If you need loads of addresses then you’re talking serious money.

There is also a need for proxies with specific purposes, whether for certain sites or particular roles. For some speed will be important and there are some providers who offer specialised video proxy servers with high bandwidth and throughput.

To remedy this issue and make sure that the costs don’t spiral out of control, there’s a new concept called rotating or backconnect proxies.  These work in a very similar way to traditional proxies but with a slight difference.  Instead of having a handful of different IP addresses assigned to the proxy itself, after every connection request it connects using an IP from a central database.  There can be literally thousands of IP addresses in this database all reserved for each proxy and these will be rotated equally.

This means there’s no risk of concurrent connections from the same address and they can be equally shared among a lot more users yet still remain ‘unique’ to each specific connection.  The practically advantage is that the cost is hugely reduced.  Compare this with something like this UK VPN service free trial system which offers a few addresses.  However there is little guarantee that you won’t be sharing those same addresses with hundreds of other users at the same time.

Hiding Your IP Address to Watch the BBC

Every single device which is connected to the internet has an IP address.  That little network number is something that you literally cannot do without if you want to access anything on the internet.  The reason is that to communicate over the web you need to use something called TCP/IP which requires every device to have a network number in order to work.

That number might look rather generic or made up, but in fact it’s unique on the internet.  No other device anywhere on the planet has the same address as you and it’s the nearest thing to a digital identity that we all have.   Unfortunately, it is also used against us in a variety of ways ranging from the annoying to the sinister.

Now we’ve probably all seen those spy or crime solving dramas where the ‘IP address is traced’ and of course this is perfectly feasible.  Most IP addresses can be traced back fairly easily to the exact device which is using it.  However more problematic is the increasing way that this address is used to filter or make more money from us.

Your IP address is also an indicator of your nationality, at least your current national location.  If I try and access my Hulu account while travelling, I’ll get blocked because it’s decided I’m not in the USA.  However the real tribulation is losing access to the BBC the minute I’m not in the UK, this is a major loss!

Now the reasons for these restriction vary from channel to channel. Hulu places restrictions probably because it has the broadcasting rights for a specific country and if you move outside this area they’re not covered.  The BBC used to be quite relaxed about allowing it’s content to be visible from anywhere but they got very strict a couple of years ago.  Yet there’s no need to worry although these channels use our IP address against us, you can actually take back control and watch whatever you want irrespective of your location.

As you can see in this video, it is possible to watch all the BBC programmes online from anywhere including Australia. You can do this by hiding your real IP address and showing a false one instead. There are many methods of doing this, however most of them involve hiding your true location by routing your connection through a server based in the correct country.

These server are called proxies or VPN servers and there are two main requirements for them to work properly. Firstly they must be undetectable, and secondly they need to be based in the location your pretending to be from. So if you want to watch the BBC then you need a UK server, for US channels you need one somewhere in the USA. There are variants of course, and a new system called Smart DNS is one of them which is becoming increasingly popular.

If you’re outside the UK, missing the BBC and want to see it in action then check out this post – Watch BBC Abroad for Free – Trial Offer which gives you 14 days to try it out. Unlike the normal VPN solutions it’s actually very simple to set up as all you need to do is modify your DNS servers. On most devices this is relatively straight forward and even means you can set this up on smart TV and phones.

One things for sure, when you take control of your IP address you regain a huge element of control when you’re online.

So What are Ticketmaster Proxies?

Have you ever rushed over to a ticket site eager to grab some a chance to see your favorite bands only to find 90 seconds after they’ve gone on sale every decent ticket has gone?  You’re left deciding between some restricted view seat quarter of a mile from the stage or paying some shark four times the cover price on eBay.

You can’t understand it because you sat in front of your computer with a credit card in one hand and your mouse poised over the buy button.  How could so many human beings have beaten you to the tickets, how is it possible for you to be that slow!   Well don’t worry you’re not alone and if it makes you feel any better the odds were stacked against you from the beginning.

how to make residential proxies

There are lots of variables that are involved when trying to grab hotly contested tickets.  Things like the speed of your connection, the distance between you and the ticket site are all relevant and largely out of your hands.  Yet the major issue is that you’re not competing with other human beings but computer software with response times in milliseconds.  Not terribly fair is it!!

The computer software is designed to select and purchase tickets as fast as possible.  Indeed it’s likely thousands were already checked out before you managed to move your mouse or click a button.  In essence you were already doomed to competing for the secondary tickets before the sales window opened.

Nobody likes this of course, apart from the individuals who snap up these tickets.  The ‘scalpers’ as they’re commonly called though can make serious money from reselling these tickets on sites all across the internet.

So how do they do this and is it possible to beat them at their own games?  It is possible and not actually that difficult but if you’re just looking for the odd ticket then it’s probably not worth the hassle.  However if you club together for friends and family and you go to a few concerts (or would like to) then it’s possible to join the scalpers in a morally superior way.

Brief Look at the  Ticketmaster Beating Technology

The easy bit, but often quite expensive is the software.  There are custom bots around which work perfectly especially those designed around specific platforms like Ticketmaster.  The technology isn’t difficult to create a Bot, however the problem is that the ticket companies are forever instigating technology to block and ban people who make multiple applications.  This means that the software is always needing updating to make sure it still works.

ticketmaster proxies

They’re not actually rocket science as you can see from the relatively crude graphical screen, but there’s a lot of work that goes into these Bots in order to keep them working hence they’re not that cheap. The best ones change a lot so you’re probably best googling for the latest Ticketmaster bots try and get a trial if you possibly can but that’s not always possible.

Ticketmaster Proxies are Essential

Unfortunately a one time payment for the bot is not going to be enough, because there’s one crucial component missing.  If you sat at your home PC and just  ran the software, your career as a concert ticket baron would be relatively short lived.

One of the major focuses for the Ticket sites is to detect multiple and duplicate connections.  They check browsers, meta data and most importantly IP addresses to ensure that people aren’t trying to make multiple applications.  the only thing that would happen if you ran any sort of Ticket Bot on your home connection is that your IP address would be blocked and blacklisted very quickly indeed.

The other essential component are proxies, servers that sit between you and the ticket site hiding your IP address and connection details.  You need the proxy to effectively create alternative personas so that the bot can legitimately buy lots and lots of tickets.   The number you require obviously depends on the scale of your purchases – if you’re just buying a few for friends and family you only need a handful of different addresses.

Now don’t think you can grab a few free proxies from the internet because they won’t work.  Most will be blocked already and anyhow they will be far too slow to effectively grab tickets quickly.  The requirements are fairly specific – you’ll find the best proxies for ticketmaster have the following qualities:

  • Residential IP addresses – although quite difficult to get these make you look like a genuine home user.
  • Not blocked by Ticketmaster – there’s little point using them if they’re already blocked.
  • Fast – speed is essential, slow proxies can completely defeat the point of using a fast bot.
  • IP switching – you need to switch addresses after each attempted purchase.

Normally these sort of requirements could be extremely expensive – as you would requite private residential proxies dedicated to you only.   However systems have been developed based on vast pools of IP addresses which proxies can rotate through automatically.  This massively reduces the price and automatic rotation ensures the IP addresses are not abused and blacklisted.

So that’s it the shopping cart if you want to move into the illicit world of concert ticket arbitrage or too throw all your scruples out of the window and make a ton of money by ticket scalping.  It doesn’t need a technological genius, just a half way decent computer, a reasonable internet connection and an investment in the software and proxies.

If you’re still keen, these are two of the best suppliers of specific ticket proxies which work and don’t cost the earth.  If you do this, try on a small scale first and then ramp up, whatever you do don’t skimp on the proxies though

Both these companies have great support and decent prices, ask them questions they’re very helpful.

Rise in Residential IP Providers

If you’re looking for an online, potential boom market then providing residential IP addresses could be the one you’re looking for.   A few years this simply didn’t exist and indeed most people (even IT professionals) probably couldn’t tell you what a residential IP address is and what you might need one for.

In the past it wasn’t actually that important, after all as long as you had an IP address then that’s all you needed.  Where it came from, what it was had no real importance as long as the address was valid and you could go online with it.  However this has pretty much changed, the IP address is taking on much more of a significance often in ways that are invisible to the end user.

Residential IP Providers

Consider that the vast majority of websites now will record your IP address in some way.  Everything from the huge international web presence to the two page geeky blog from your favorite online author.   Some will have installed complex systems to do this but more commonly it will be available through Google Webmaster or Analytic tools.   Potentially any web site can glean lots of information about you the very moment you visit the site.

This might be disconcerting to some, who probably still think that there’s a default level of privacy available online as long as you don’t start filling in forms or posting under your real name.  The reality is that there’s virtually none, unless you take some concerted effort there’s no privacy at all.  Your IP address is the key to your location, your identity and the link that allows webmasters to make all sorts of assumptions and decisions about you.

One of the most important factors that people are beginning to look at is the classification of the IP address.  For the home user who’s logging in from a connection to an internet service provider then that’s almost certainly going to be classified as a ‘home or residential’ user.   Believe it or not that’s a very powerful and important indicator for many websites – it marks you as being a potential customer.

Look at this video about using private proxies for Instagram, and you’ll get an idea of why many people value these IP addresses so much.

A residential IP address is a normal user who is probably accessing their website from home. As opposed to a user from a commercial address who could be at work or worse using a VPN or proxy to hide their true identity. What’s more this ‘residential address’ can also be located much more easily to a specific location. Imagine how important it is to an e-commerce website that they can determine that a visitor is a normal home user from the US or Europe. Indeed many e-commerce websites are only really interested in specific users, i.e. those who are potential customer as opposed to informational websites which have a much broader brief.

Why the Need for Residential IP Providers

There is obviously a temptation for the webmasters to focus on the people that who will potentially buy from them. After all a local store in downtown Chicago is going to prize residential addresses located in the Chicago area. Whereas visitors from commercial addresses or those located on the other side of the world are much less likely to become paying customers. There are many options the web site can take even with this fairly basic pieces of information – route them through to special areas, make special offers and so on. Indeed many web sites will use it to filter out potentially ‘bad traffic’ – e.g fraudulent transactions are much likely to come from a remote IP address or one diverted from a commercial data center through a proxy.

It’s following this logic that some companies have used this to help block entire sections of IP addresses based on location and classification. It’s most common in the entertainment industry where movies and shows are often licensed on a ‘per country’ basis. For example you can’t watch the BBC online unless you have a British IP address and you can’t access Hulu without an American IP address and so on. The country based restrictions are extremely common and are usually referred to as geo-targeting. People are generally able to bypass these restrictions and blocks fairly easily by using VPNs and proxies with servers based in the required countries.

Netflix however has introduced a very restrictive filter which blocks many of these servers. It’s not enough to have an IP address based in a specific country, you also have to have am address which is classified as ‘residential’ too. A normal VPN or proxy won’t work anymore as these have addresses usually allocated from commercial datacentres. There’s an interesting article about the concept here – Why You Need a VPN with Residential IP for Netflix, which explains what the media giant has done. For many VPN companies this meant the end of selling to potential Netflix users simply because the required addresses are so difficult to obtain.

You can still  get access to Netflix and indeed there are some companies who offer residential IPs with proxy servers and even a residential VPN.   However there’s not many of them and you should check carefully especially if you need to access a service like Netflix which only works with them.   Other companies also restrict access based on the classification – for example many social media sites like Instagram and Facebook check the origin of IP addresses.   As such many internet marketers or online businesses invest in static residential proxies in order to operate multiple accounts for marketing purposes.

You can buy residential proxies yet remember they can be expensive simply because the IP addresses are very difficult to obtain.   Where you buy them from very much depends on what purpose they are needed for.   If you’re looking to access social media or e-commerce sites then you should look for specific location – i.e to buy multiple items from the Adidas web store the best residential proxies would be those based in the US.  You’d also need many more addresses if you’re operating multiple accounts or making lots of purchases,

For accessing resources like Netflix all you need is an address based in the US, there are a couple of VPN solutions which have a selection of residential US proxies.  These can  be used to access the US version of Netflix – here’s the best options and you can test it for 14 day for free.

If you’re looking for cheap residential proxies for building Instagram accounts or building a Sneaker business then you’ll need a lot more.  The following is one of the few residential IP providers who actually own the servers that their addresses sit on.

Why People Change Their IP Addresses

If you want to access the internet then you’ll need an IP address, otherwise you won’t be able to connect to anything.  That funny little network address is essential in order for you to do anything online simply because no computer would ever be able to find you.

streaming UK TV

For most us that address is assigned directly from our ISP when we connect up to the internet.  Each device is allocated an address from a range and it will use it to communicate online.  For many of us that address will not change for weeks on end and forms the basis of  our digital profile while we use the internet.

So why would we want to change this address? Why isn’t the IP address we’re assigned good enough?  Well the simple fact is that although you have little say in how your IP address is assigned, it does actually affect what you can do online quite significantly.   Your address is also used to determine your location which can also have an impact on your online experience.

Take a look at this brief video entitled Online IP changer and you can see some of the situations where it’s actually useful to have the ability to change your own IP address,

As you can see from the demonstration, your address is actually used to block and filter what you access online. SO for example many of the world’s best media site only allow access to their domestic markets. So to watch Hulu or HBO you have to be physically based in the US for example. Even if you are from the US and travel abroad, suddenly you’ll lose access to resources that you were previously able to access without issue. This is because you cannot take your IP address with you when you travel, well at least under normal circumstances.
As soon as you travel to France for instance, you’ll be consider a French person as you’ll have an IP address registered there. Which means you will get blocked if you access a US only website.

This is why proxies and VPNs are so important now as they give people some control over their digital identities. Anyone can use an intermediate server based in a different country in order to hide their location. So a US traveller could connect through a US proxy and enjoy the same access to US media sites that he had previously.

Proxies and IP Cloaking

Many people think  that all IP addresses are pretty much the same.  Of course, the numbers change but fundamentally one address is very much like another.  To some extent if we roll back the clock a couple of decades that would be true but in the new era of the internet – your IP address says quite a bit about you.

IT’s difficult to imaging that those random looking numbers in the format 192.168.1.1 have any real significance, but i’s actually become more important.  For example if you have the IP address – 23.248.183.211 I could easily determine a few facts including your location and who you use as an internet provider.

ip cloaking proxies

The specified address for example comes from a range assigned to Nigeria, so anyone using it is based in Nigeria or relaying through a server based there.  As it’s unlikely anyone would get any real advantage from using a Nigerian IP address then it’s probably that’s their real location.  Although some people do use Nigerian proxies for various semi-legal or criminal activities simply because law enforcement standards are fairly low there.

Websites will use this information for all sorts of reasons, although commonly marketing is the main driver.  Although IP addresses are also used extensively to restrict access.  For example if you try and post an advert on a US Craigslist site with a Nigerian IP address then you’ll simply get blocked.

Our IP addresses control what we can access and to some extent our online experience.  A digital entrepreneur from somewhere like India or Nigeria will have a much harder time than one from Chicago for example.  Access to marketing sites, advertising and payment processors will be much more difficult.  Nigeria’s reputation for online scams and fraud unfortunately makes life much more difficult for all their honest entrepreneurs too.

Which is why many such people use proxies in order to hide their true IP address and take advantage of a new one.  Our digital marketer in Nigeria may for example want to buy lots of trendy US merchandise to import and resell online, he won’t have much luck with a Nigerian address.  However by renting a proxy he can operate online with a UK or European address quite easily.  He may get to a more advanced level and use rotating residential proxies to buy stock from restricted releases like concert tickets or sneakers.

This in just one example but it illustrates the growing market in private proxies and VPNs designed to allow people to operate without these restrictions online.  Business people aren’t the only ones which use these services to hide their location.  There’s an even bigger market for ordinary people who just want to access movies, films and videos which are also blocked based on your location.  This post illustrates how a special method using name resolution and proxies can be used to access the BBC online – check it out it’s called BBC iPlayer DNS.  The method involves routing selected packets through a UK proxy based on specific DNS requests.  So the DNS server would wait until it sees a request for a geo-restricted site like the BBC only then route through a UK server so it worked properly.

 

DNS Considerations When Migrating Hosts

When migrating web host to a different hosting service’s server or modifying the server’s IP address, the most important factor to consider to guarantee to maintain schedule of the sites hosted on the server, decrease the downtime of the website, prevent strange difficulties such as emails get delivered to either server randomly, or browsing at old server, is how fast DNS (Domain Name System) will be able to check out or fix hostname or domain into your brand-new IP address, instead of the old IP address. Unfortunately, webmasters have actually limited ability to control or bypass the DNS propagation process. Nevertheless, there are still a few ideas, techniques and workarounds that guarantee DNS cache will refresh the new IP addresses as soon as possible.

DNS acts in such as aside that when an ask for IP address received by DNS resolver, it will then query the root hosts to discover the authorized server with comprehensive understanding of the specific domain name. If a legitimate IP address for the domain is returned by the reliable server, the DNS resolver will cache the DNS proliferation for a provided time period called TTL (Time To Live) after an effective reply, in what called DNS caching in order to decrease the load on specific DNS server. DNS caching provides resolution of domain to IP to happen locally using the cached info rather than querying the remote server for subsequent requests, till the TTL period expires.

The Time-To-Live (TTL) timer is the trick to ensure that the DNS cache ends immediately and all of the time remains fresh. TTL is specified by domain administrator in the authoritative DNS server for the zone wherever information stems, and its worths inform DNS caching resolvers to end and get rid of the DNS records after TTL seconds. Lowering the TTL value will make it possible for quick expiration and revitalizing of DNS records, making the new records to propagate faster across the world. Still, the technique demands the name resolvers comply the RFC standards, which most do. Alongside, you must have complete control to alter the name server reliable for your domains.

The tweaking of TTL in DNS records need to be done a number of days prior to it will alter (date of server moving or IP change) to guarantee that all DNS caching resolvers picks up the fresh TTL value and expires the old longer worth. The trick will cut down the TTL in anticipation of the alteration to reduce disparity during the modification, inning accordance with RCF 1034.

TTL is defined by Minimum field in SOA (Start of Authority) type as default TTL, or individually at each record as TTL. RCF 1912 explains the Minimum field in details as listed below:

Minimum: The default TTL (time-to-live) for resource records (RR)– for how long information will remain in other nameservers’ cache. ([ RFC 1035] specifies this to be the minimum value, but servers seem to always execute this as the default worth) This is by far the most essential timer. Set this as large as is comfortable provided how typically you update your nameserver. Remember if you’re routing your connection through any other intermediary then name resolution can be effected.  For example if you’re using something like a VPN or ATC proxy then the DNS servers may change from the client configuration.

If you plan to make major modifications, it’s a smart idea to turn this value down temporarily ahead of time. Then wait the previous minimum worth, make your modifications, confirm their correctness, and turn this worth back up. 1-5 days are typical values. Remember this value can be bypassed on individual resource records.  Which is the way some Smart DNS solutions create specific records to bypass region blocks, you can see an example in this post about accessing US Netflix.

If you are utilizing a web-based or GUI to manage your domain’s DNS records, and after that visit to the system, and edit the SOA records. Inside you’ll see a field called Minimum, change the value to as low as possible (in seconds), such as 300 for timeout every 5 minutes. Then alter the TTL for all the A, MX, CNAME, TXT, SOA, PTR and other records, if appropriate.

If you are using cPanel WebHost Manager (WHM), log-in and choose Edit DNS Zone under DNS Functions section. Pick the suitable zone (domain). You’ll be given with a list of records. Modify the minimum ttl in SOA, and TTL column of A, MX, CNAME and other records specified.

For those by hand set up the authoritative nameserver for a domain zone using BIND, modification has to be done in the zone file. For example, so domain zone example.com, you will see the following resource records in the zone file.

Wireless Security Initial Concepts

Wireless security is an important part of your wireless network Without even getting Wireless Security into wired Wired Equivalent Privacy (WEP) there are certain things you can do to make your network secure and shut down the easy avenue for the hacker attacks.

An acronym for Wired Equivalent Privacy, WEP is an encryption scheme used to protect your wireless data communications.

WEP uses a combination of 40-bit keys to provide access control to your network and encryption security for every data transmission. To decode a data transmission, each wireless client on the network must use an identical 64 or 128-bit key.

Securing Wireless Networks

Ever since 2001, the use of wireless networks has exploded both in home and corporate environments. By 2006, more than 80 millions wireless local area network (WLAN) nodes should be in the hands of residential and business users combined.

Securing WLANs has been a concern almost since their inception and while much progress has been made with the introduction of WEP and WPA, both have been shown to have their own weaknesses or implementation issues.

While 802.11i is said to improve upon WEP and WPA, it is not yet commercially available and it may prove over time to have its own weaknesses as well.

There are wireless security steps that network administrators and home users alike may take to augment the security of their wireless networks, and discussing some of these steps is the purpose of this site.

None of these steps is intended as a replacement to WEP or WPA, but rather as a complement. Many of these steps do not apply to public hot spots, however, as it is generally the intent of the spot’s owner or operator to make access as easy and convenient as possible.  After all we use our networks for an increasing amount of our lives from entertainment to household and financial management.

Just have a look at this video which demonstrates how an ex-pat has turned their wireless network into a home entertainment portal. Although the channels listed are not accessible outside the uK by relaying through a third party server you can hide your location. It’s doesn’t always work but there are solutions you can see – Netflix America in UK. It’s an example why a fast, secure wireless network has become something of a necessity in the modern world.

Please remember that computer security is a complex issue and it would take volumes just to explain all of the ins and outs, but if you take some precaution to secure your wireless home network, you’ll have a basic understanding of this technology and a excellent start.

Quick Tip: All wireless devices must use the same WEP key!

Adapters and access point and other equipment all come with a default password and other settings – You should quickly change these values. Leaving these default values unchanged, just invites trouble, remember this is your private network, but the airwaves are public and the door is open to anyone that’s up to no good.

The most important values to change are the SSID, make sure this setting is the same for all devices in your wireless network.
A few things you can do to make your SSID more secure

  • Make it unique
  • Change it regularly
  • Disable SSID Broadcast

The SSID (Short for service set identifier) also referred to as a network name because essentially it is a name that identifies a wireless network.

Is the unique name shared among all devices in a wireless network. The SSID must be identical for all devices in the wireless network. It is case-sensitive and must not exceed 32 alphanumeric characters, which may be any keyboard character.

Quick Tip: It is important to note, however, that using the manufacturer’s default SSID, makes it easier for hackers or individuals to identify the access point’s manufacturer and look for specific weaknesses that may be used to gain unauthorized access or deny others access.

Make sure this setting is the same for all devices in your wireless network to insure Wireless security, I recommend that you change the default SSID to a unique name of your choice.

Disabling SSID broadcasting can be a useful security feature. However, when SSID broadcasting is disabled, Wireless site survey tools such as Windows XP’s Zero Configuration utility will not function.

It is best to disable the SSID broadcast until you have configured all of your wireless network clients.
