RFC 1035 Response code - this 4 bit field is set as part of responses.

Variants
No error condition
Format error - The name server was unable to interpret the query.
Server failure - The name server was unable to process this query due to a problem with the name server.
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.
Not Implemented - The name server does not support the requested kind of query.
Refused - 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 transfer) for particular data.
Reserved for future use.
