    Enumeration ResponseCode

    DNS RCODE values (the response status, low 4 bits of the flags word).

    NOERROR is success. The session layer maps SERVFAIL / REFUSED / FORMERR / NOTIMP to a ProtocolError on the typed paths, while NXDOMAIN (the name simply has no records) does not throw for resolve. The raw DnsSession.query exposes the rcode unchanged.
