The mechanism for specifying how the delegation happens should allow the zone to be delegated to more than one name server—presumably the primary would be the CPE device, but someone who really cares about the reliability of the reverse zone, if there is such a person, would want to set up a secondary elsewhere and keep it up to date with zone transfers or the like. _______________________________________________ DNSOP mailing list DNSOP@ietf.org https://www.ietf.org/mailman/listinfo/dnsop
