You might found many web proxies in the internet, but did not know what it is. Basically it helps you surf the web anonymously. When you surf the web it is possible to get information about you like IP address, your country, what operating system you are using, what browser you use, and many other information.
When you visit a web site, information about you can be retrieved and used to track your Internet activities. So if you need privacy, then you can use anonymous proxy servers. The proxy server replaces your Internet address for its own. This will hide your IP address and making it harder for people to trace you.
You can search Google for “Proxies” if you want to try it.
