You asked on bind-users, so I assume you wanted to know about BIND, not DNS in general. Other servers have other methods. In BIND, you do this by setting up two views, each with a different version of the zone. View A has a match-clients statement covering A.A.A.A, and has response Y; view B has a match-clients statement covering B.B.B.B and has response Z. There are some other ways to do it too, e.g. with response-policy zones or the DLZ perl module, but views are easier. -- Evan Hunt -- e...@isc.org Internet Systems Consortium, Inc. _______________________________________________ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
