Why not configure DHCP to assign a given IP address to a MAC address. Thereby you are using a static IP from DHCP:
# Test server host test { hardware ethernet 00:1D:32:3C:DD:2C; fixed-address 192.168.0.253; ddns-hostname "test"; }
Obviously, I'm using DNS also.
Is that bind configuration? It looks as if that might be the way to go if none of my routers can help me.

Is it possible to set up a Linux system so that it has a fixed IP address on the LAN but uses the addresses given to it by a router (using DHCP) for DNS?
Dynamic DNS updates - assuming you are using bind:

Not quite what I meant. I'll try and clarify.....
I don't run a DNS server on any of the Linux boxes here. There are three Linux systems, one windows system and occasional visiting (usually Windows) systems. There are also a couple of printers and a DECT telephone system.
Currently most of the above have fixed IP addresses on the LAN and I have /etc/hosts (or the Windows equivalent) with the addresses in it. I manually set the DNS addresses in resolv.conf. Obviously 'visiting' systems use DHCP.
What I'd like to do is to have all systems use DHCP as then I wouldn't have to configure so much but it seems to me that I need fixed IPs for a number of things (the printers, some of the Linux systems, etc.). So if I could set a system's IP address but tell it to obtain everything else it needs to know (e.g. in particular the DNS server addresses) by DHCP it would make life much easier.
Alternatively I suppose I could set up bind in one of my Linux boxes and tell everything else to use that as the DNS server although even then I don't quite understand how things like printers work. If a printer acquires its IP address by DHCP how do you use it?
