I wonder if the best thing to do would be to define an ANAME/AAAANAME that can be negotiated by resolvers. If the resolver supports it (it can let the auth know via EDNS0) then the ANAME/AAAANAME is returned without resolution. If the resolver doesn't support it, then a synthetic A/AAAA can be returned. -- Colm _______________________________________________ DNSOP mailing list DNSOP@ietf.org https://www.ietf.org/mailman/listinfo/dnsop
