If one's not doing DDNS updates (updating a DNS server with DHCP configured records), which sounds like it, then it's probably better to directly specify so, than have a half-configured server. i.e. ddns-update-style none; > However, this line can be important: > authoritative; Hmm, I'd have thought that'd only be needed if you had more than one DHCP server on a network (a bad idea unless they're deliberated configured to be co-operative), or if you used a PC on different networks, but it may well be required. Taken from the dhcpd.conf man file: "Network administrators setting up authoritative DHCP servers for their networks should always write authoritative; at the top of their configuration file to indicate that the DHCP server should send DHCPNAK messages to misconfigured clients. If this is not done, clients will be unable to get a correct IP address after changing subnets until their old lease has expired, which could take quite a long time." -- Don't send private replies to my address, the mailbox is ignored.
