2. Exactly how did you manage to get replies from net 127 addresses? I
could SWEAR that 127 is marked reserved for localhost. It would certainly
be possible to set up a network on 127; most routing software doesn't care
too much about 127, but it'd be kinda goofy.
Linux boxes at least responds to everything on the loopback interface. I'm
guessing this is some form of loopback optimization..
