And such names should not be in use.  Only heirachical host names
should be in use now.  Heirachical hostnames contain interior
periods.  RFC 921 actually said what was supposed to happen.
Unfortunately some operators of TLD's failed to pay attention.  Just
because DNS servers didn't block a record being added that didn't
make it correct for them to add it.
