I had a old man friend, who didn't want to police to find him. so he took off the numbers on his house address. authorities and creditors couldn't find his address. However neither could the mailman or anybody else
An IP address is the method used to locate computers in the internet- you cannot fully anonymize browsing, since the data has to get to your PC somehow, and the server needs to know where your PC is to send it.
You can find limited success from proxies and so forth, but there is no 100% solution.
I think the real question is WHY you need to "hide" your IP address?
