Actually RFC3565 does NOT say to return A records in the additional section in response to AAAA queries. It does say that both AAAA and A records should be returned if additional section processing would have previously returned just A record Mark > > Shuki -- Mark Andrews, Internet Software Consortium 1 Seymour St., Dundas Valley, NSW 2117, Australia PHONE: +61 2 9871 4742 INTERNET: [EMAIL PROTECTED] -------------------------------------------------------------------- IETF IPv6 working group mailing list [EMAIL PROTECTED] Administrative Requests: https://www1.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
