This makes little sense. Most nameservers host more than one zone (e.g.
both forward and reverse zones, and also frequently a zone for
127.in-addr.arpa). It has to look at the name in the query section to
determine which one of these zones to return.
What happens if you use "dig" rather than your own tool?
