I know that RoadRunner "hijacks" any non-URLs. Basically, if what you type in doesn't go to an actual page (what would normally give you a DNS/Site not found error), it sends you to it's own branded search page. I think there are other ISPs out there that does this, too. I don't know of any way around this, though.

"You need me. You wouldn't be much of a hero without a villain. And you do love being the hero, don't you. The cheering children, the swooning women, you love it so much, it's made you my most reliable accomplice." -- Lex Luthor to Superman, Question Authority, Justice League Unlimited
