COM/NET/EDU nameserver changes

[Mark Andrews]

The gtld nameservers are being upgraded this week.  They will no
longer return glue as a answer.  This will mean that some broken
delegations that "worked" last week will no longer work by the end
of this week.  In particular "glue only" delegations will be much
more visible.

Below is what the new referrals look like.  Note the answer section
is empty.
