        We could use your help in the PIER wg.  The areas you have identified
        are areas that need a lot of work.  (Note that I have renumber large
        chunks of space three times, 127 class C nets, a class B and part of
        a class A)

        If you could help identify those vendors who make use of a), then
        we could take soem time to wrok with them on other methods.

        b) is being worked on by Dave O'Leary and c) is part of the Dynamic
        DNS work.
