As we all know, there's a rule against sharing your Wizard101 password, and if you do that, you'll be banned from the game forever. I'm about to log onto my account at somebody else's house with a different IP Address, what if I get banned? It was still me! Would you get banned for logging in your Wizard101 account with a different IP Address?
I would think not. Would you be banned if you moved, and had a different IP? I'm sure that you will not be banned. I sign on my laptop all the time if I'm traveling, but it's not sharing your password as long as you don't tell your friend your password.
