There is a way to reset your ip address... but if you don't do it right, it can mess up your computer. If you really want to know how send me a pm and I'll give you exact details.
All you need to do is login with a proxy and once you're in, you could turn it off and you'll be able to surf around normally in neopets with no proxy at all.
if you had just logged in with a proxy and used that to cheat in the first place that you wouldn't be ip banned XD but yeah if you want to get back just use a proxy for the next 6 months then when your not ip banned anymore try keeping like that using a proxy for when you cheat ^^
oh i remember it it is somewhere on hydrascape in the forums. its no-IP. but you have to be a member to get it.
