One thing the root should know - as a rule is the location of localhost.
There is after all just one address associated with it There
should be no localhost queries to the root as a rule - but misconfigured
servers result in this traffic to the root which is listed as invalid.  If
the root gave an answer instead of NXDOMAIN these queries would go away.
