While risking being slightly off topic: Does anyone use anycast dhcp servers?
Have you run into any problems considering synching the leases?

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?
