While risking being slightly off topic: Does anyone use anycast dhcp

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.

Because clients will switch to unicast for renewal. Also clients will stay
with the current server forever, so you might have a bad distribution of
load between the servers. If one server was down everyone will switch to
the other and never go back until forced.
