Re: DHCP vs RARP?

That's how I would do it. If you want the DHCP server to enforce the lease (that is, not give the same address out twice) you can create a class with all the hardware addresses in it, and then a pool that is only allowed for that class with the one address you want to share. But I'm guessing that's more trouble than is required here.

I just use separate host entries with the same fixed-address entry which
makes for a verbose dhcpd.conf file but it works. For example:

host euclid {
hardware ethernet 00:14:22:ab:ea:b6;
fixed-address euclid;
}
host euclid-wpi {
hardware ethernet 00:13:02:8e:1e:a0;
fixed-address euclid;
}

I've never checked if there's an easier/cleaner way.
