Help required to test some Negative Responses from Bind Server.

[Alan Clegg]

SERVFAIL:   create a delegation NS record in your zone to a server that
isn't authoritative for the zone being delegated.
REFUSED:  create an ACL that matches (and denies) the query being done
NOERROR w/ no RR:   query for  example.com AAAA

As for NOTIMP, I'm not aware of an easy path, but I'm sure that someone here
knows.
