No such restriction exists. Any RRtype can appear in any zone/domain. The DNS protocol does not impose any constraints on which RRtypes can go where. There are some corner cases arising from policy, not protocol, matters however. For example, a zone signed with DNSSEC-bis probably won't have NSEC3 or NSEC3PARAM records while one using DNSSEC-ter probably won't contain NSEC records. _______________________________________________ Acme mailing list [email protected] https://www.ietf.org/mailman/listinfo/acme
