IP Hider masks the real IP of a user, allowing him to browse all kind of pages without ever worrying that the ISPs or any other marketing tool is monitoring your surfing habits or spammers are attacking your computer.
The simplest way to do this is to have traffic redirected through anonymous proxies. A proxy server is a kind of buffer between your computer and the Internet resources you are accessing.
The data you request come to the proxy first, and only then it transmits the data to you. As a result, the websites see the IP address of the proxy server instead of your own IP address.
