[plug] Basic DHCP questions

Not really. You can pretty easily do it for the core machines on a small 
LAN (or a big one - our servers are coded in so that they're always at 
the same IPs) and let transcient clients have undefined DNS names, etc - 
or define them as "transcient1.localnet" etc.

ooh any refs to this? I'm _really_ interested in getting auto-updated 
DNS zone files as dhcp allocations change but am not satisfied with the 
somewhat clunky script based methods I've seen so far.
