way past "additions to the NSFnet PRDB"

Well, yes and no. I still think that if you get your customers to register allocations in a local registry -that they own- that it provides them with ownership. As a component of delegation comes the requirement that a registry be run. With the requirement to run a registry comes the mandate to mirror the data back to a central repository. This allows folks to register local routing preference, but this can be overridden higher up. Not to beat the DNS horse too much, but its like we do in-addr assignment now. We will delegate it to you, but reserve the right to keep a secondary of the zone locally. Much of this thinking comes from reviewing rfc1291. More food for thought. -- Regards, Bill Manning
