I am confused here.  Do you have control over the

     example.com

zone and its name servers?  Or is this just some zone on the Internet
that you are attempting to query.  I would love to try to reproduce
this, but I have no way of querying that zone, as it really is not a
"real" zone with name servers ns[123].  If the real zone being queried
were present in the original posting, then maybe some of us could do
some research.
