But none of those had a 198.32.136.x address... The bigger problem (the one I was thinking about) would be someone putting a host on 192.41.177.x or 192.157.69.x or 198.32.136.x or ... Most providers carry the 192.41.177/24 (MAE-East) etc... routes and "know" how to get to them, so any machine hooked up with the IP out of the network of a major XP has the potential to get "free" full or partial Internet connectivity. *That*'s the big problem you have to make sure to avoid if you want people to play with you (if you're an XP operator).
