Ok cause you are asking it nice
Do you mean while surfing the net?
You can never realy hide/mask (in theory) your IP for everyone cause your IP is used to deliver the nfo to you. (TCP/IP remember)
BUT
you can mask your IP by using some tricks:
- use an anonymizer http://www.anonymizer.com
- or use some (one or more) public proxy:
there are many lists of public proxies available. (search on AO forum --> this is discussed before)
The basic idea is the following if you use a proxy, the proxy will handle all the requests for you, this way, the other side only sees your proxy IP and never your own (if you use a good proxy).
Alright here is some summary
For a good explaination about proxies and a list, look at this thread:
