Currently you can't use /31 networks. However, there is an RFC that proposes changes that would allow their use on point-to-point links only.
RFC 3021 Using 31-Bit Prefixes on IPv4 Point-to-Point Links. A. Retana, R. White, V. Fuller, D. McPherson. December 2000. (Format: TXT=19771 bytes) (Status: PROPOSED STANDARD) Just an FYI, Karen >>>>>>>>>>>>>>>>>> Original Message Good...... but you can't have a subnet with 31 bits.... that would leave 2 > "hosts" and the network address and the broadcast would use them up, so you > end up with 0 hosts per subnet. For point-to-point serial links, you'd > usually use a /30 (255.255.255.252) which gives you 4 addresses per subnet > (1 network, 1 broadcast, and two hosts) > Mike W.
