How to Make a VPN Undetectable & Bypass Blockers in 2021

VPNs work hard to keep you secure and anonymous every time you go online. But what happens when the thing that’s designed to keep you safe is detected and blocked itself? This is known as VPN blocking, and it’s a big problem.
Some ISPs, websites, online services, and even governments actively look for VPNs and block their connections. This can keep you from accessing content from around the world or even using your VPN for quick, anonymous browsing on public WiFi.
But with the right VPN service like ExpressVPN and a little know-how, you can get around these blocks without reducing your privacy or security. Plus ExpressVPN offers a 30-day money-back guarantee, so you can try it risk-free.
Keep reading to find out how VPNs are blocked and what you can do to stay undetectable.

Why Do VPNs Get Blocked?
From copyright to censorship, there are many reasons why websites block VPNs. And if you’re in a region with tough digital surveillance, VPN blocking is even more intense.
There are several reasons a VPN could be blocked
Government Censorship
In some areas, governments impose strict internet censorship. They may block websites that don’t support the culture and values of their country so that residents can’t digest info that’s contrary to a particular cause. Worse, these types of countries also often regulate the use of VPNs, blocking vendor sites and app stores so you can’t download these services.
The most obvious example of strict government censorship is China. Its Great Firewall restricts all kinds of sites, including Google, social media apps, YouTube, and even some news websites. China also blocks most VPNs so that you can’t get around its rigid control.
Other countries with digital restrictions include Turkey, the UAE, and Iran. Many social media and streaming sites are banned in these countries, as is the use of VPNs.
As you can imagine, finding a VPN that can somehow stay undetected from government censorship is hard. But don’t fret—I spent weeks researching hundreds of services and found three reliable options.
Streaming Location Restrictions
Ever tried to access the Netflix library of another country? You were most likely redirected right back to your own. That’s because streaming sites like Netflix lock down their content to specific regions. Netflix isn’t the only one, either. Many streaming sites only allow access in certain regions—BBC iPlayer, Hulu, HBO GO, and ITV Hub are just a few examples of platforms that employ these geo-restrictions.
While some sites are exclusive to a single area, such as Hulu in the US, other sites like Netflix offer different libraries depending on where you are. This is often due to broadcast and streaming licenses. So if you’re not in the country where access is allowed, you’re blocked from tuning in. And they don’t make it easy to get around these geoblocks; Netflix’s proxy error is one of the toughest to defeat.
Copyright
Some internet service providers (ISPs) limit VPN use to stop copyright infringement. While many VPN users engage in P2P sharing to send and receive files like images or videos, others use torrenting for illegal piracy—they download copyrighted movies and songs.
Limiting VPN use blocks all VPN users, regardless of what they do online. But if your VPN can prevent your ISP from seeing that you’re using a VPN, the ISP can’t interfere with your online activities.
School and Workplace Restrictions
Most schools and workplaces introduce restrictions so you can’t access certain websites. This might include, for example, YouTube and social media sites. To stop you from accessing these sites, they may also block VPNs—at least while you’re connected to the institution’s WiFi network.
Bust Through VPN Blocks with ExpressVPN!
Types of VPN Blocks
There are many reasons why a VPN gets blocked. But have you ever wondered how exactly they’re blocked? Thankfully, the most common techniques are also the easiest to get around.
IP, port, and DPI blocks are the most common VPN blocks
IP Blocks
When you connect to your VPN, it masks your real IP address and displays the server’s IP address instead. This means that when head over to Netflix US while connected to a US server, Netflix will see a US IP address. Theoretically, this means any geo-restrictions should be easy to get around. But it’s not always as simple as that.
Many sites keep a log of identified VPN IP addresses. If you hop onto a server that uses an IP address on that list, you’re blocked straight away. This is the reason why many VPNs can’t access sites with tough geoblocks, like Netflix and BBC iPlayer.
Port Blocking
Most VPNs use specific ports when they connect to the internet. These ports are identified by numbers and function as tunnels that internet traffic is routed through. For example, when you use the OpenVPN security protocol, your traffic is usually sent to port 1194.
It’s easy to block certain types of traffic when that traffic always uses the same port—all a website needs to do is monitor that port and block the traffic it doesn’t want. When that happens, you can’t get onto your favorite sites, VPN or not. Port blocking isn’t as common as IP blocking, but it’s still easy to get around by simply switching ports.
Deep Packet Inspection (DPI)
DPI is a highly advanced way of blocking VPN traffic. Rather than checking where the traffic comes from, sites look at the type of traffic instead.
When you use a VPN, your traffic is anonymous. But certain security protocols, like OpenVPN, use unique cryptography signatures that can be detected and blocked. OpenVPN is commonly blocked as most VPNs use this as their default protocol, which means sites block traffic because they think you’re using a VPN. Even though no one can actually see your traffic, they can see that it’s been encrypted.
This kind of VPN block is particularly tough to bypass. It’s a technique that the Great Firewall of China uses to restrict VPN use, and that’s one of the reasons why finding a VPN to use in China is difficult. But if you have a VPN that allows you to change security protocols, it’s possible.
Bypass Tough VPN Blocks with ExpressVPN!
How to Bypass VPN Blocks
Now that you know how and why VPNs get blocked, it’s time to think about how you can get around the restrictions. First of all, you need to make sure you choose a high-quality VPN that offers everything you need—I’ve rounded up my top recommendations of undetectable VPNs later in this article. There are a number of techniques you can try with your chosen VPN.
Avoiding VPN blocks requires strong security
Obfuscated Servers
Obfuscated servers are advanced features that usually only come with leading VPNs. To understand how they work, first think about your standard VPN connection: When you connect to a VPN server, anyone who sees your connection—including your ISP, government surveillance agencies, and other third parties—can see that you’re using a VPN. These viewers can’t see your actual traffic, but they can see a signature that indicates VPN usage.
An obfuscated server hides your VPN traffic altogether. It scrambles your data to make your VPN traffic look like any other internet traffic, removing identifying metadata so anyone watching will think you’re just a regular internet user.
These servers add another layer of anonymity, so your browser traffic and VPN traffic are completely hidden simultaneously. Since your VPN appears as normal traffic, it makes it easier to bypass VPN restrictions. This feature is ideal for places with tough digital censorship, like China, where most VPNs are completely banned.
Obfuscated servers also scan for open ports to send your traffic through, instead of always using the same one, which significantly reduces the risk of you being detected. It’s unlikely there’s someone watching every possible port to potentially block VPN traffic. And it’s even less likely that your traffic will be blocked using obfuscated VPN servers since no one even knows you’re using a VPN.
Dedicated IP Addresses
Dedicated IP addresses are another great feature to have, and it’s something you should look for in a VPN if you’re worried about being detected. Usually, you can purchase dedicated IP addresses on top of your monthly VPN subscription.
VPNs tend to use shared IP addresses. This means that when you connect to a server and obtain an IP address, all the other users on that server will also have that same IP address. All it takes is multiple people with the same IP address accessing a platform like Netflix to make it easier for the service to spot the VPN usage. All Netflix needs to do then is block that IP address.
A dedicated IP address helps you get around this issue by assigning you a unique IP address that you don’t share with anyone else. So even though you’re using a VPN, Netflix will only see you with that IP address, no one else. As you’re not sharing that identifier with anyone else, the sites you visit are more likely to think you’re just a regular user accessing the internet from your device in your home country—and that means you won’t get blocked.
Server Switching
Sometimes you can solve VPN blocking by simply switching to another server in the same country. It’s not uncommon for servers to be blacklisted, but if a VPN has a large server network, you can just try disconnecting and connecting to another. Most leading VPNs offer regular IP refreshing, too, so sites like Netflix can’t possibly keep up with all the new IP addresses.
It’s important to choose a VPN with a higher server count so you have less of a chance of getting blocked, but you also need a VPN that offers unlimited server switching, too. That way, you’re free to connect to as many different servers as you like.
Change Ports
With ports being monitored, sometimes all it takes to avoid detection is to switch ports. You can find VPNs that already do this for you—many scan ports automatically when you connect so that you can evade blocks. However, you can manually change ports, too. These are the best ports to switch to:
Port 443: Unencrypted traffic comes to this port to be sent to a secure version of a website. For example, if you’re shopping online and about to check out and enter your credit card details, you’ll be sent to the HTTPs site. It keeps your personal details and banking information safe from being leaked. It’s a good idea to change to this port since it’s less likely to be blocked as all normal secure website traffic is routed through here.
Port 80: This port is also used for encrypted traffic (HTTPs). It secures all HTTPs sites, so it’s rarely blocked.
If your VPN allows it, you can also use the Secure Socket Tunneling Protocol (SSTP) protocol. Unlike OpenVPN that uses port 1194, the SSTP protocol uses port 443 by default. Since this port secures all website traffic, it lets you avoid detection as your traffic is unlikely to be blocked. There are other security protocols you can use, too, which we’ll look at next.
Get Advanced Security with ExpressVPN!
Change Security Protocols
Most VPNs offer a variety of security protocols, so it’s not always easy to know which one to use. In most cases, I’d recommend OpenVPN as it’s the most modern protocol and comes with speed and security in one. However, if avoiding detection and blocks is your main concern, switching to other security protocols can help. Many blocking algorithms check for OpenVPN traffic, which makes it harder to evade blocks.
The protocol you should use depends on your chosen VPN and what it offers, as well as your internet needs. You need to know what to expect from each one because in most cases, you’ll compromise somewhere on either speed or security. For instance, if you’re just looking to get onto a geoblocked streaming site, you’ll want faster speeds. But if you want to secure your online traffic and share anonymous files, you might be less bothered about speed and want stronger security features.
L2TP/IPSec
These are two different protocols that are combined. Layer 2 Tunneling Protocol (L2TP) doesn’t offer much in terms of security, but it has decent speeds. So it’s paired with Internet Protocol Security (IPSec) to fully encrypt your traffic and shield you from any leaks. However, the extra security slows you down somewhat, so you’d be better choosing this protocol if you’re more concerned about detection than speed.
IKEv2
Internet Key Exchange v2 (IKEv2) uses IPSec’s level of security and has fast, reliable speeds. It’s a good choice for mobile devices as it has the ability to reconnect you if you temporarily lose your internet connection. However, it can be tricky to set up, and it’s only compatible with a limited number of devices.
SSTP
As we’ve seen, SSTP is a strong choice for getting around VPN blocks. It uses port 443 alongside all other secure internet traffic, so it’s highly secure. However, it’s only available on Windows devices.
WireGuard
WireGuard is a fairly new security protocol that uses OpenVPN’s security with IKEv2’s speeds. It’s a great security option, but only a few VPNs offer it right now, like CyberGhost. It’s also only available on Linux devices.
PPTP
This is the most dated protocol, and I wouldn’t recommend using it unless you absolutely have to. It offers high speeds, but it lacks decent security, so you’re at high risk of leaks and exposure to anyone watching you—risky if you’re somewhere with strict digital censorship.
Some VPNs offer their own security protocols, too. These are usually reliable for bypassing geoblocks and come with high speed and security, so make sure you check these out when you’re deciding which protocol to choose. Want to know more? Check out our security protocols quick guide.
Choose from Multiple Protocols on ExpressVPN!
Switch to Mobile Data
If you’re in the workplace or at school, you can avoid most VPN blocks by simply disconnecting from the WiFi and switching to your mobile data. The restrictions in place are usually just limited to WiFi. Remember, though, unless you have an unlimited data allowance, activities like streaming and gaming can quickly eat away at your data.
Other Ways to Avoid VPN Blocks
Does your VPN not offer obfuscated servers? If you’re familiar with VPNs or are a more tech-savvy user, you can try other advanced methods for avoiding VPN blocks.
Tor Browser
Tor, also known as The Onion Router, is a free, open-source software that lets you surf the web anonymously. Your traffic enters the Tor network through an entry point, where it’s then sent through a number of random servers or nodes, before it reaches its final destination.
It’s called The Onion Router because your traffic is wrapped in layers of encryption to keep it anonymous. Layers of encryption are removed as your traffic moves through each node in the network so it can be identified at the exit point.
On its own, however, the Tor browser isn’t completely secure. Your IP address can still be identified at the entry and exit nodes, which are heavily monitored by surveillance agencies and hackers to detect, block, and intercept traffic. Your IP address also means your exact location can be found at these points, too.
You can find VPNs that are compatible with the Tor Browser, though. Look for a VPN that uses VPN Over Tor, which means you connect to the Tor network first and then a VPN server. This adds another layer of anonymity and privacy, as your data is completely encrypted while you’re browsing—even at the entry and exit nodes. Since your traffic and IP address can’t be identified, it’s harder to block you.
SSH Tunnel
SSH tunneling is an advanced way of encrypting your traffic and bypassing blocks by sending your data undetected through filtering services. You can create an SSH tunnel by using local port forwarding. This means connecting your current device to another device elsewhere to bypass a block.
Let’s say, for example, that an online shopping website is blocked at your workplace or school. You can create an SSH tunnel to connect your work laptop to your computer at home. This fires up a new browser using a different port, like port 80, to go onto the online shopping website. Your encrypted data is sent to your home computer, but when it reaches its destination there, it’s unencrypted.
This method is used in a host of different applications, including sending and receiving files via FTP, so it’s rarely blocked. But SSH tunneling does come with slower speeds, so I wouldn’t recommend it if you’re trying to stream.
It works on the reverse, too. This is called remote port forwarding, where you can access servers on your work computer from your home network, for example.
SSL/TLS Tunnel
SSL/TLS tunnels are similar to SSH tunnels in that they’re encrypted. SSL/TLS tunnels are used for encrypted HTTPs online traffic or anything that deals with private data, like on your online banking website when you’re transferring money.
Most VPNs offer this feature by default, so you can use it with your VPN. Any prying eyes monitoring port 443 will find it hard to identify whether you’re coming through as regular HTTPs traffic or VPN traffic, so you’re less likely to be blocked.
If your VPN doesn’t offer this software, you can download it yourself. But it can be time-consuming to set up.
SOCKS5 Proxy (Shadowsocks)
The SOCKS5 Proxy works by using the Socket Secure 5 protocol to transfer data using a proxy server. SOCKS also adds a layer of authentication that ensures that only the intended user can access the proxy. This makes it a very effective method of anonymizing and sending traffic—perfect for sharing files via P2P.
The proxy uses remote servers to help you bypass blocks, especially in censorship-heavy countries like China. Here’s how it works: Imagine that your normal IP address is 1234. When your traffic is sent through the proxy server, you’re given a new IP address, which might be 5678. If you’re in China trying to get onto Google, all Google sees is your 5678 IP address, not your actual device IP address. This lets you bypass any blocks.
One thing to be aware of, though, is that a proxy isn’t completely secure. While it uses authentication, it doesn’t wrap your data in encryption like a VPN does. You can find VPNs that support SOCKS5 connections so you can combine them for maximum security and restriction-free access.

The Best VPN for Bypassing VPN Blocks – Full Analysis (Updated October 2021)
To make sure your VPN is undetectable to websites and services looking for it, you need to choose a high-quality provider. A service that offers advanced features like obfuscated VPN servers, various security protocols, and a large network of IP addresses isn’t always easy to find. But without these features, you risk being detected and blocked.
After lots of research and testing, I’ve rounded up the three best undetectable VPNs so you can continue to browse, stream, and torrent without worry of blocks.
ExpressVPN – Best for Security Protocols
3, 000+ super-fast servers in 90 countries
Obfuscated servers and a range of security protocols
Compatible with Tor
DNS leak protection
Works with: Hulu, Crunchyroll, ESPN, Netflix, BBC iPlayer, Hotstar, Disney+
Compatible with: iOS, macOS, Linux, Android, Windows, Chromebook, routers
ExpressVPN is a high-speed VPN that comes with military-grade encryption and security measures. I’ve tested it for weeks and found that it’s easy to use, has reliable and super-fast connections, and guarantees access to sites with the toughest geoblocks, even if you’re in China or Turkey.
We decided to put this so-called unblockable VPN to the test by trying to access Netflix USA, BBC iPlayer, and DAZN from the Netherlands, India, New Zealand, and South Africa. In all cases, our operatives were able to bust through these notoriously strict geoblocks to access each service. It was possible because ExpressVPN has lots of servers—3, 000 servers across 90 countries. It also refreshes its IP addresses regularly, making it difficult for websites to maintain blacklists.
ExpressVPN has multiple security protocols, so it’s a great option if you want to modify your connection to ensure you’re undetectable. During our tests, we could choose from L2TP/IPSec, SSTP, and PPTP as alternatives to OpenVPN. OpenVPN is the default option, but it’s easily changeable through the settings area. We enjoyed exceptional speeds with each protocol, even the slower ones.
We wanted to know if ExpressVPN could defeat the Great Firewall of China, so we had agents in Shanghai, Taipei, and Guangzhou give it a try. They used the VPN’s obfuscated servers and were virtually invisible—Google, YouTube, Instagram, and other banned sites unlocked instantly.
No matter how you connect, ExpressVPN uses 256-bit AES encryption to shield your personal information. There’s also DNS leak protection to stop your traffic being leaked and compatibility with Tor for maximum anonymity.

FAQs
Are VPNs legal?
Despite what you may think, VPNs are actually legal in many countries. Most locations don’t place restrictions on using a VPN at all, but not every country is the same. China in particular has cracked down on VPN use in recent years, blocking nearly all VPN services. Other areas that restrict VPN use include Turkey and the UAE. You can read more about the legality of VPNs in our quick guide.
Regardless of whether using a VPN is allowed or not, using your VPN for illegal activities like downloading copyrighted movies and songs is considered criminal activity.
Can I use a VPN to avoid blocks on my mobile?
Yes, absolutely. As long as you use a VPN that’s compatible with your mobile device (all the ones in my list are), you can easily bypass blocks on your mobile phones and tablets.
Can I use a free VPN to bypass VPN blocking?
There are plenty of free VPNs out there, but I’d always recommend a premium vendor over a free one. As you’d expect, free often means limited, especially in terms of security protocols.
Hardly any free VPNs can unblock sites like Netflix as they don’t refresh their IP addresses regularly enough. They also hold back on security measures, like kill switches, encryption levels, and no-logs policies, which could compromise your anonymity. It’s rare to see advanced features like obfuscated servers, choices of security protocols, and dedicated IP addresses with a free VPN, either. All of these things are important for bypassing VPN blocks.

The Bottom Line
Even as the world becomes more connected, you may find yourself unable to access more and more content due to geo-restrictions. The websites that control this content are working hard to block VPNs and restrict your access—as are some government agencies in certain countries. That’s why you need a VPN service that’s just as smart and resourceful.
I recommend ExpressVPN because its obfuscated servers, multiple security protocols, and Double VPN feature make it practically impossible to detect. But all of the VPNs on my list will help you maintain access to everything the internet has to offer, with no blocks.

A VPN is ideal for streaming the latest Avengers movie and binge-watching The Good Fight or Atlanta.
Unfortunately, streaming services like Netflix, BBC iPlayer, and Hulu have become aware of VPNs and block access due to agreements with studios to geo-restrict certain content. The method of IP blacklisting is where streaming sites identify a VPN by matching the IP address to those of known VPN servers.
However, there are tricks to make your VPN undetectable and free from blacklisting. Read on to discover how to make your VPN undetectable in 2021:
Successfully bypassing all restrictions requires a quality VPN service. We advise a premium VPN service over a free one to ensure a secure and private connection. A free VPN may seem like a good deal, but in reality, they are limited, so, before you choose your service for the price, consider the implications.
The best VPNs to choose from are those offering maximum security and features you can tailor to your specific needs. The ability to adjust your VPN service is the key to successfully overcoming IP blacklisting.
The following VPNs are our top picks for remaining undetected while using streaming services, etc.
1. ExpressVPN
Desktop and mobile clients for multiple devices
AES 256-bit encryption
Fast connection speeds
Multiple protocols
Unblock Netflix feature
Try Now Risk Free
2. CyberGhost
Cost-effective
Packed full of features
Zero log policy
User-friendly interface
After choosing a VPN service, you can now make the necessary changes to improve your security and avoid IP blacklisting. Successfully doing one of the following can make your VPN completely undetectable:
Change Your Encryption Protocols
Most VPN providers offer different protocols for encryption. The standard encryption is AES 256-bit with an OpenVPN, which is one of the most effective ways of encrypting your data. Switching encryption protocols will allow you to bypass firewalls put in place by certain websites.
Here are some protocol configurations you can alter:
OpenVPN
The default protocol used by most VPN services. If you want the most basic level of protection, this is the perfect protocol for you.
L2TP/IPSec
When paired with Internet Protocol Security, Layer 2 Tunneling Protocol is slower than OpenVPN but more secure. If you don’t care about speed, but want to remain undetected, this is a great choice.
SSL/TLS
Transport Layer Security is the successor to Secure Sockets Layer and is less common than other protocols. If your VPN provider offers this, switching can make your VPN undetectable.
SSH
Secure Shell Tunneling is similar to SSL but less popular and usually restricted. You may need to contact your VPN provider to enable it, but SSH can bypass almost all firewalls.
Switch VPN Ports
Ports act like a tunnels sending information to your ISP. Companies can monitor port numbers and traffic and block what they want, therefore, switching ports can allow your VPN to remain undetected.
Try switching to the following ports:
2018 – Good for avoiding ISP blocks.
41185 – Good to use with lower port ranges blocked.
443 – Rarely blocked and the standard port for encrypted traffic.
80 – Another rarely blocked port.
If your VPN provider doesn’t allow the modification of your service, there are other methods worth considering. For these methods, you may need a little more experience with VPNs.
1. Tor Browser
The Tor browser is a long-standing and popular tool for anonymity you can use in conjunction with a VPN. Unfortunately, with Tor, you can’t stream, meaning Netflix, BBC iPlayer, and Hulu will be inaccessible.
Furthermore, Tor will slow your connection significantly. If you’re looking to remain undetected, but not stream, Tor is a viable option.
2. Shadowsocks (SOCKS5 Proxy)
Designed for heavily censored countries like China and Saudi Arabia, Shadowsocks allows users to browse the internet without restrictions. Using the Socket Secure 5 protocol, data transfers between clients and servers through the proxy server, providing a layer of authentication to ensure only the user can access the proxy.
This method is faster and more reliable than others. However, it’s not easy to set up and can cost more than a VPN. Although great for remaining undetected and accessing IP blacklisted sites, it should be a last resort.
3. Use Your Own VPN Server
If you can’t find a VPN that allows you to change the protocols or ports you need it is possible to set up your own.

Do proxies really provide anonymity? - Server Fault

Do proxies really provide anonymity? – Server Fault

Do web proxies really provide anonymity?
I mean, without someone asking for logs in a web proxy server for who/when connected, is it impossible to know who was behind that IP address?
I’m asking this because I heard somewhere that some technologies (like “flash”) bypass personal IP information for requests or something like that.
(I’m a noob in server configuration and concepts like DNS and proxies. Thanks! )

No, just setting a proxy within your browser not make you anonymous.
Your browser and flash is likely to have cookies that will identify you.
If you wanted to be truly anonymous you would probably need to fire up a new browser from a livecd or in a VM, set the proxy, and then browse. To maintain your anonymity you must not login to any site that has your name.
You will probably also need to make sure the browser/OS you are using does not make DNS requests to a local DNS server. If you do not configure the proxy correctly your machine make make DNS requests for the sites you are visiting to the local network.
If the proxy you are using is not using SSL for transport your ISP or someone on the local network will still be able to see what you are doing. Even if they are using SSL your ISP will know you are contacting that proxy.
If the an evil person cannot get the logs from the proxy machine to get the logs. if they are able to monitor the incoming and outgoing traffic they still may able to identify you just by looking at the flows of data.
Something like TOR does the best job, but even with it you must be very careful that you set it up properly and that during your session you never reveal any information that would unmask you.
It depends on what you’re trying to obscure and how it’s configured. Proxies aren’t meant to hide people; they’re meant to cache data, and later they started scanning content to filter it or protect people on the inside from malware. Anonymous proxies act anonymously by promising to not give out or retain logs (you have to trust them on that) and anyone trying to trace where the request is coming from is stopped at that hop if the proxy strips data out of the request that is personally identifiable.
Basically, the proxy has to be configured specifically to strip out identifiable data.
If the request or post information has your ID or personal information or something like that embedded in it, then that kind of defeats the purpose too.
If the request has to get back to your computer somehow, there is definitely a trail that leads back to you. Just depends on how obscure it is to trace. Commercial anonymizers just promise to stonewall by purging logs and stripping data from the request (if you trust them), and networks like Tor obscure your request by bouncing it all over the place (more info on their website) to obscure it and make tracking extremely difficult.
If you run a proxy at home, it doesn’t take a forensic expert to know that there’s a very limited number of people that could be making web requests from that home network.
But if you were truly 100% would the data get back to you?

I run a squid server at home, with a very basic/default setup, and I’ve seen websites identify me by my internal address. I’m not sure if the website is getting from my browser or the proxy, but it definitely can be found with my particular setup.
Knowing your internal IP addy really isn’t a big deal. NAT (or proxies that accomplish the same thing) violates the principles of end-to-end routing in the first place, since there are now computer connected to the Internet (through a NAT router) which do not have a “routable” address. I wouldn’t call your IP personal information, not anymore than the street address on the front of your house.
To your larger question about proxies providing anonimity. Cookies can uniquely identify you with or without proxies. Websites can also do a browser fingerprint on you, and that basically uniquely identifies you without a cookie.

>Anonymous proxies do many things, such as change an ip address, encrypt information, and most of all ensure a person’s safety. A proxy will supply you with a fake ip address in place of your old one. This will keep anyone from knowing your true identity on the internet. The key behind how anonymous a proxy really is, is owning a proxy under a reliable company. Everything you do on the internet will go through the company’s proxy first, so the company could just be out to steal your personal information.

Even if the proxy is configured to strip out anything that might identify you, the operators are scrupulous and the system is impenetrable against hacking (as if! ), depending on local laws it may still be required to maintain logs that can identify your machine. It may sound a bit altruistic but I think an operator that disrespects the law should probably not be trusted to respect your privacy.
