DHCP is certainly not stateless, which is why there is a concept of leases, which are stored in a file. You can't have 2 servers answering for the same subnet without some sort of coordination, or you would have a potential for duplicate addresses being assigned.
Duplicate assignments are not a problem as long as you ensure that the client is the same. I.e. if the prefix delegating DHCPv6 server serves a statically assigned prefix to an end user based on information *uniquely identifying that user*, then you can replicate that setup to as many completely independent DHCPv6 servers as you like. Different end users will still not receive duplicate assignments. But if you want the DHCPv6 server to dynamically allocate a new prefix to each client, then you are up for problems of course. Don't see why you would want to do that though. Redundant DHCPv6 will be only one of many problems in such a setup. Bjørn
