It's usually a good idea to have a central registry of which computer
has which IP addresses, with MAC address info. Once you have that it's
easy to also generate a dhcpd.conf from that info to assign static IP:s.
And heck, dnsmasq is even easier to set up for that. You can just
populate /etc/hosts and /etc/ethers (as per their specifications), and
dnsmasq will use that for static DHCP assignments. I.e.:
/etc/hosts
192.168.1.5 blue
192.168.1.6 green
192.168.1.7 red
192.168.1.8 brown
/etc/ethers
00:11:22:00:00:aa blue
00:11:22:00:00:bb green
00:11:22:00:00:cc red
00:11:22:00:00:dd brown
Make sure "read-ethers" is uncommented in dnsmasq.conf, and you're set.
(Okay, there are a couple other configuration changes required before
dnsmasq will DTRT, but that's true of ISC's dhcpd, too.)
I even have a script that takes a file with the format:
mac ip hostname
and spits out the appropriate /etc/hosts and /etc/ethers. :-)
FWIW, I manage ~20 networks with static DHCP, many of which have machines
roaming to and fro.
