This is very WELL possible!
In XP there is a neat little feature that will allow you to create an IP conflict on your PC. This will make your ISP think your IP is "taken", and therefore assign you a brand new one through their DHCP, automatically!
It's very easy if you know how, won't cost a novice more than 5 minutes to pull it off. My company will release an E-Book on the subject in the coming months. (Unless some IP masking or proxy selling website buys us off meanwhile)
This has only been tested on XP, with Cable connection (so no DSL). But with that configuration it HAS been tested in numerous countries with numerous providers. All in Europe, but it is pretty clear that it works anywhere if you have dynamic IP through cable.
(Of course it will also work in a home network, but that's no good... Another internal 192.Blah.Blah IP wont do you any good. It's the outside IP that you want to change if yr banned or such)
