Ideally I would agree, but there are some passable operational reasons for this to happen, and there are also some good operational ones as we enter IPv6-land. Instead, I agree with another poster who suggested a mismatch or absence of this data in the DNS is good input to a scoring system, but not good grounds for outright rejection. -MSK _______________________________________________ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list [email protected] https://lists.isc.org/mailman/listinfo/bind-users
