Although in this particular instance, those aren't the applicable
fields. Since SCO's nameservers are returning NXDOMAIN for
www.sco.com, the response will only be cached for the value in
the (*horribly* misnamed) "minimum" field.

  sco.com. 1800 IN SOA ns.calderasystems.com.
  hostmaster.caldera.com. 2004020105 3600 900 604800 1800

The very last number in the reponse is the "minimum" SOA field,
which is the time in seconds the negative query should be cached.
