The most common way to hide your ip address is to use an anonymous proxy server. keep in mind tho, that most of these proxy servers and especially your isp keep logs of all connections and traffic. therefore, if someone really wanted to track you down, it is very possible. depending on why you feel you need your ip address hidden, there are several options. One easy way is to keep internet tracks to a minimum is to use a public computer at a local university or at the library. There are other ways I am sure that work very well, prolly connecting to multiple anon proxies that dont keep records or something, but prolly more hassle that it is worth, unless you are doing something you REALLY dont want to leave tracks doing, then you prolly should do a lot more research about this. doubt you will find the answer on this board anyway.
