- According to RFC 950, you can't have a subnet address of all zeros or all
- ones. In *your* case you have a subnet of all zeros.
-
- So your valid host address will be from 65 to 191.
-
- If you need more than two subnets, or don't want to subnet further your
- going to need to get more class C addresses. I have reluctantly determined
- that thats what I have to do. There just isn't enough address to properly
- subnet for people stucl with class C addresses.
-
- Another option would be to use bridges, avoiding the need for subnetting
- completely. There is the Public domain PC Bridge which should fit your
- needs, but yo have to dedicate a PC to each bridge.
