RFC 1035 documents the details of the DNS protocol:

RCODE           Response code - this 4 bit field is set as part of
                responses.  The values have the following
                interpretation:

....

                3               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.
