Ive just ran a few different IP checkers on my connection.

Location: Marina Del Ray nr Santa Monica USA !!!

Im not using any sort of IP faker although I do use one occasionally (Vidalia on a G4 iBook).Ive closed down the program rebooted the modem and computer but Im still in Marina Del Ray

Anyone know how or why this could be?

need more info, where are you? And who is your ISP?

Check your proxy settings
