(This is a perfect example of quoting ASCII documents; 
I couldn't do this with a PostScript file!)

RFC1122                      INTERNET LAYER                 October 1989

            IP addresses are not permitted to have the value 0 or -1 for
            any of the <Host-number>, <Network-number>, or <Subnet-
            number> fields (except in the special cases listed above).
            This implies that each of these fields will be
	    at least two bits long.
