Re: masking an ip
Well, people can force the proxies to give up your true IP address. That's when you start getting into going through multiple proxies to make it harder to track.
Basically, the proxy downloads whatever you asked for, and then it sends it to you instead of you directly downloading it. That way, the download server or whatever logs the proxy IP, not your own. Good free proxies are hard to find, but Google is your friend.
