I confess that is pretty nifty. Interestingly enough I get 3 different behaviors with respect to that "special" address on 3 different 0Ss.
If i try to ping www.ulwebnet.com from a freeBSD machine, I get a ping return from the Layer 3 switch on the network it's plugged into (the
gateway address). On a debian linux machine I get a ping return from localhost. On windows XP pro I get: "Destination specified is
invalid." and no ping attempt actually seems to be sent towards 0.0.0.0
for whatever it's worth,
