      Barry,

   There is a good reason for arguing against a cluster of class B (or C)
addresses over one A (or B). When one is in a situation where there is
one portal (or just a few portals) into a cluster of networks, and those
networks are richly interconnected, then subnetting is a win. For
networks outside the portal, only the underlying network needs to be
known to make routing decisions. With clusters of non-subnetted networks,
each network needs to be known outside the portal. Adding one address
to the routing mess is vastly preferrable to adding many.

                                Later,
                                    Bob
