Proxy servers allow you to surf and browse the Internet without directly connecting to the destination sites. The sites you are connecting to will not see any requests or log entries from your IP address, but from the proxy server instead. Thus, you are able to surf in secrecy and change your IP address.
One of the many proxy networks, BigProxyNetwork.com [no longer available] is used by those trying to unblock websites at work or at school including, Myspace and Facebook. The proxies from this list can also be used to access geographically filtered Internet users, and those that wish to use the Internet with some privacy.
So, if you are looking for some US web proxies to hide your IP address, check out the ones listed below:
