RFC8020 is about how a resolver should treat NXDOMAIN it does not say when it can expect an Authority to return NXDOMAIN so this is orthogonal usage cases. The main motivation if I recall correctly for starting the work on RFC 8020 was to deal with ENT names correctly, i.e. it is a valid name thus do not return NXDOMAIN for it. I will argue even further: an Authority can decide while responding to a specific query what kind of negative answer it returns: Literal or “Lie” For most of its existence DNS Working groups in the IETF have avoided the rathole of treatment of answers by end-user. Olafur PS: if the real reason for RFC8020 was lost during the work of the working group editing process that would not be the first time it happened. > > R's, > John > > PS: THe urge is great to subit an erratum for 8020 which replaces the entire > text sith "just kidding." > > _______________________________________________ > DNSOP mailing list -- [email protected] > To unsubscribe send an email to [email protected] _______________________________________________ DNSOP mailing list -- [email protected] To unsubscribe send an email to [email protected]
