This is a constructive and helpful posting, Tony. Thank you. Am I correct in presuming that both Noel and you believe that the possible technical solutions to this problem are currently being considered in the RRG / RAM discussions? -----Original Message----- From: Tony Li [mailto:tli@xxxxxxxxx] On Sep 12, 2007, at 10:57 PM, Noel Chiappa wrote: > Let me see if I understand this.

I believe that a more constructive assessment is that enterprises are unwilling to pay non-trivial costs to renumber, and ISPs are unwilling to pay non-trivial costs to support a non-scalable routing subsystem. This perspective is soluble, but it's not the perspective that we seem to approach the problem from. We also don't have the solution in hand today, but work towards it would be greatly accelerated by backing away from our long-standing positions, terminologies and arguments and truly focusing on the problem at hand.
