This is because ACCD has lame system administration.  They are using a
windows box of course.

They delegated a /27 network, but it isn't set up properly on their
server.  Note that the server above, 209.184.112.66, is NOT in the
cis.sac.accd.edu zone.


Lame Delegation

    When an NS record points to an incorrect host. This can be caused when:

        * A zone is delegated to a server that has not been properly
configured to be authoritative for the zone.

        * A server that is authoritative for the zone has an NS record
that points to another that is not authoritative for the zone.

    This will cause resolvers to direct queries to servers that will not
respond authoritatively, if at all. This causes unnecessary network
traffic and extra work for servers. 1/4th of all zones have lame
delegations (source Domain Health Survey).
