DNS_ERROR_RCODE_NOT_IMPLEMENTED

DNS_ERROR_RCODE_NOT_IMPLEMENTED represents DNS RCODE NOTIMP. The server received a request but does not implement the requested operation or query behavior. It can occur when a client uses an unsupported DNS opcode, record type, extension, or management feature against an older or restricted server.

What to check

Record the exact opcode, record type, and server version involved in the request.
Retry with a conventional A, AAAA, or SOA query to establish whether ordinary resolution still works.
Use a supported DNS Server management interface when the failed operation was administrative rather than a normal name lookup.
