My understanding was that the intended usages are slightly different: *.invalid could be used in places that if it accidentally got out onto the internet it would do no harm to any legitimate domains. It was also acceptable for a resolver to recognize that .invalid was "invalid" and short circuit the DNS lookup. sink.arpa seems to be intended to allow for recursive lookup and a proper NXDOMAIN to be returned as normal. I think that it is specifically intended NOT be treated specially by resolvers. -- Bill McQuillan <McQuilWP@xxxxxxxxx> _______________________________________________ Ietf mailing list Ietf@xxxxxxxx https://www.ietf.org/mailman/listinfo/ietf
