The reverse lookup doesn't really have to match the host's own idea of it's hostname - it just has to return something that you can log. One approach is to run your own nameserver that is primary for your private ranges (no sense in bothering the root servers for them...). Then if you don't want to set up the DHCP server to give out IP addresses tied to MAC addresses you can you use names like dchp-ip-number for the names you return. -- Les Mikesell lesmikesell@xxxxxxxxx
