YXDomain
YXRRSet
RR Set Exists when it should not. See rfc2136.
NXRRSet
RR Set that should exist does not. See rfc2136.
NotAuth
Note on error number 9 (NotAuth): This error number means either “Not Authoritative” rfc2136 or “Not Authorized” rfc2845. If 9 appears as the RCODE in the header of a DNS response without a TSIG RR or with a TSIG RR having a zero error field, then it means “Not Authoritative”. If 9 appears as the RCODE in the header of a DNS response that includes a TSIG RR with a non-zero error field, then it means “Not Authorized”.
NotZone
Name not contained in zone. See rfc2136.
DSOTYPENI
DSO-TYPE Not Implemented. See rfc8490.
