If the network is correct, then the DHCP server should check if the client's notion of its IP address is correct. If not, then the server SHOULD send a DHCPNAK message to the client. If the DHCP server has no record of this client, then it MUST remain silent, and MAY output a warning to the network administrator. This behavior is necessary for peaceful coexistence of non-communicating DHCP servers on the same wire. at first, everything is simple if (wrong net) { should nak; } else { if (!ok ip) { should nak; } } but then the "If the DHCP server has no record of this client" clause is thrown in. At what stage of the block does this go in? I would say this clause would go *before* 'if (wrong net)'. I'll cc this to the Dynamic Host Configuration working group. Hopefully they'll have some answers. _______________________________________________ dhcwg mailing list dhcwg@ietf.org https://www1.ietf.org/mailman/listinfo/dhcwg
