nslookup is braindead. Seriously, it's hopeless. The problem is that
nslookup can't find a reverse entry for 216.112.229.114. Why it thinks
that's important is anybody's guess. You can shut it up by adding a PTR
for 216.112.229.114 if it's not there already.
OTOH, you should consider using a different tool. Dig is a much better
choice.

IIRC 'domain' and 'search' are mutually exclusive. Use one or the other.

hudson doesn't seem to think it's hosting 168.192.in-addr.arpa. Is there
a zone {} clause in the named.conf telling it to load
168.192.in-addr.arpa? At the moment it thinks blackhole.isi.edu it the
master nameserver.
