Hmmm you could change your IP if you're not using Static... IF you're using dialup simply reconnect to the internet. If you're using a Dynamic host, then either your dynamic server holds your MAC assigned to a certain IP for a certain amount of time, then you have to be disconnected for however long your server unassigns it, but most cases you can simply release/renew your connection in cmd.
released and renewed, did nothing at all for my ban
