As long as those records are generated from the target name that would probably be okay. But the current draft doesn't seem to enforce it, and, (probably unintentionally/implicitly) allows the following setup: aaaa.example.com. ANAME aaaa.example.net. aaaa.example.com. AAAA 2001:db8::aaaa ; not populated from ANAME target aaaa.example.net. AAAA 2001:db8::bbbb This looks more like a prohibited "CNAME + other AAAA for the same name" situation to me. -- JINMEI, Tatuya _______________________________________________ DNSOP mailing list DNSOP@ietf.org https://www.ietf.org/mailman/listinfo/dnsop
