Named sends FORMERR. > IXFR over UDP is defined (RFC 1995 Section 2), but not implemented > (apparently) by BIND. So NOTIMPL would seem appropriate. Named sends back the current SOA record over UDP. This is equivalent to "up to date" or "retry over TCP as the answer will not fit in the space available" depending upon the serial in the request.
