> There was a huge online audience that revolted at the idea of an IP address that doesn’t exist — in one of the scenes, there is an octet above 255, which would not be a proper IP address, and there were many people who screamed about that. The story behind that is simply that legal would not let Sam publish a real IP address because that would be irresponsible and inappropriate. Sometimes you lose those battles, and Sam had to put a bad IP address in the scene.
