Do you really have 128 hosts on the same piece of wire? Basically, if you want to have a subnet of 32 hosts, you *must* split a 128 into 2 x 64, then split one 64 into 2 x 32. You can put two subnets on the same piece of wire, but it is ugly, and packets from one to the other still have to go via a router. Danny
