Below is a nslookup result with "set debug".  Does anyone have a full 
understanding  for id=15 in line 3 ?  Is the the 15th query from a 
particular client before the ttl, expiration day, or otherwise?  Thanks.

Got answer:
   HEADER:
       opcode = QUERY, id = 15, rcode = NOERROR
       header flags:  response, want recursion, recursion avail.
       questions = 1,  answers = 0,  authority records = 1,  additional = 0

   QUESTIONS:
       cnf.com, type = A, class = IN
   AUTHORITY RECORDS:
   ->  cnf.com
       ttl = 7200 (2 hours)
       primary name server = dmrqs004.cnf.com
       responsible mail addr = dns_id.dmrqs004.cnf.com
       serial  = 2003110400
       refresh = 3600 (1 hour)
       retry   = 1800 (30 mins)
       expire  = 604800 (7 days)
       default TTL = 7200 (2 hours)
