We can't help you do something that difficult (if not impossible). You're not running OC* internet connections that you can just cut on and off whenever you want, you're probably using Cable/DSL at best with an ISP, and it'll take time to re-acquire your IP address, because you can't have two people with the same IP, or it'll cause conflicts.
Oh, and uh, you're not paying anyone here anything, so you didn't bring any business here to take elsewhere.
