How did I get IP?

Alright, I just downloaded Zattoo to view BBC 1, 2, 3 and 4. However, I need a british IP to do that. Is there a way to get another Ip without using slow proxies? Are there any fast and reliable british proxies?

I was just thinking that all you could really use IP Spoofing was for sending a UDP packets to an unsuspecting computer, either having them originate from your computer while pretending to be from somewhere else, or to have a remote service send UDP packets to the wrong computer. Turns out it's called a UDP flood attack.
