- NXDOMAIN is an authoritive answer, so when receiving an NXDOMAIN, we're done. From RFC 1035: Name Error - Meaningful only for responses from an authoritative name server, this code signifies that the domain name referenced in the query does not exist. FROM RFC 8020: When an iterative caching DNS resolver receives an NXDOMAIN response, it SHOULD store it in its cache and then all names and resource record sets (RRsets) at or below that node SHOULD be considered unreachable. Subsequent queries for such names SHOULD elicit an NXDOMAIN response. - REFUSED can be a transitional status: (https://www.ietf.org/rfc/rfc1035.txt) The name server refuses to perform the specified operation for policy reasons. For example, a name server may not wish to provide the information to the particular requester, or a name server may not wish to perform a particular operation (e.g., zone) Other errors are now logged as debug-message, which can be useful for troubleshooting.
