| 3.2. Completeness of the Response | | A resolver SHOULD consider the address information found in the | additional section complete for any particular server that appears at | all. In other words: if the additional section only has an A RRSet | for a server, the resolver SHOULD assume that no AAAA RRSet exists. | To ensure equal availability the A and AAAA RRSets should have | identical TTL values at the authoritative source.
The last part doesn't make much sense because client queries can cause the A and AAAA TTLs to drift apart anyway (cf. section 3.1). _______________________________________________ DNSOP mailing list DNSOP@ietf.org https://www1.ietf.org/mailman/listinfo/dnsop
