With a table.
Look at dhcpd.conf, it does the same thing. You put the MAC, and the
name of the machine (you can put the IP number, but we've always
used the name). Then the machine makes a DNS lookup for that name
and gets it's IP number.

You can use DHCP to assign static IPs, we did this for, at our peak,
about 200 linux servers. It's nifty because you can make your
start-up scripts que off of name for clustering, and dynamically
re-assign hosts to clusters by simply changing the dhcpd.conf file
and rebooting.
