Think about the 127 net for a while. Most systems have a route '127.0.0.0/255.0.0.0' pointing at the local host, right? Where does 127.0.0.1 go?
Yep, I'm well aware that 127 is the loopback net (though I'm sure a dozen more people will point it out to me before the end of the day :).. I was just looking at the probability that a random 32 bit (the simplest possible way to generate a spoofing address) address would be reachable. By my measure, the most straightforward method of generating addresses should prove quite effective. If I filter out addresses on nets 0, 10, 127, 192.168, and 248-255, I get about .113%. This was not intended to be an accurate measure of the number of real sites, just how many addresses were "reachable." -- "Love the dolphins," she advised him. "Write by W.A.S.T.E.."
