I believe that something like this should work for the ISC dhcpd (version 2,
anyway):
deny unknown-clients;
host x1 { hardware ethernet de:ad:be:ef:f0:0f; }
host x2 { hardware ethernet f0:0f:de:ad:be:ef; }
and so on.
The important thing is the "deny unknown-clients;" line. That changes the
server from the default mode where it's a bit free and easy with it's
addresses. You then have to explicitly tell the server about each of the
machines you want to have an address. It's not greatly different to setting
fixed-address on a specified host, but since there's no address fixed, the
host will be given whatever's available.
Note: this is taken entirely from the dhcpd.conf(5) man page. I haven't
tried this myself, so if it breaks something you get to keep both pieces.
