The problem is most likely to be nslookup. [Please throw this program
in the bin. Use dig for DNS troubleshoting.] Ancient versions of
nslookup make inverse queries. Modern versions of BIND don't support
this obscure query by default. So if you use an old version of
nslookup to query a BIND8 name server, it doesn't work. Either you use
the version of nslookup that comes with BIND8 or else tweak named.conf
so the name server supports these worthless inverse queries from
ancient versions of nslookup.
