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
