RFC 1034, Section 3.6.2: "If a CNAME RR is present at a node, no other data should be present; this ensures that the data for a canonical name and its aliases cannot be different. This rule also insures that a cached CNAME can be used without checking with an authoritative server for other RR types." via http://www.bind9.net/BIND-FAQ DNSSEC changes that a little in as much as a node can have an RRSIG with a CNAME, but what good is a rule without an exception? :) _______________________________________________ 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
