I think i had it working a year ago - but on the other hand, my linuxbox
wasn't on 24x7. My named configuration is attached (and i dont think i
have made any changes (except for to after i changed to another internet
supplier - cablemodems are nice ;-)

I havent got any experience with dhcp....but..
I think that's a combination of configuring the dhcp server with _very_
long timeouts (or renegotiating intervals). That way each dhcp client
will get the same ip each time it connects, and you can put the ip and
name in configuration files for named.
- or maybe the dhcp server has some specialised way to do this show...
