Since DHCP uses broadcast and multicast addresses when a client is
discovering a server, it's not obvious why you'd have to.
You can run redundant sets of isc-dhcpd servers together serving the
same broadcast domain and have them assign leases from the same address
pools (at least, I've never tried it, but I was within internal mailing
list range of the person maintaining that code and heard him shouting
fairly often about it, not always in tones of rage and frustration).
Was that what you were after?
