If you are going to register PTR records for clients with changeable IPv6 addresses, then you need a dynamic update mechanism. Mark Andrews made a recommendation earlier in this regard. I don't think there is any reason to have PTR records that have no corresponding AAAA records in the forward lookup zone. That would be computationally infeasible anyway. Jeff.
