And yes, a capture shows confirms indeed that dig returns less information when
the BIND 9.16.33 DNS server is used.
I guess you can easily reproduce that behaviour, unless it is due to a
mis-configuration bit on our DNS server ?
I could not reproduce as the query currently returns NXDOMAIN
AFAIK different servers may return different results depending if they have
the requested record in cache or not.
+norecurse only asks server not to send query out, it doesn't prevent
returning cached record.
