......... Walter O. Haas is rumored to have said: ] ] I've formed an intuition that, if all IP addresses were portable (ie. ] independent of ISP) and assigned on a strictly geographic basis, then ] there would *automatically* be clustering of addresses equivalent to ] that obtained from CIDRization as a result of marketplace forces and ] the practicalities of technology. While this would perhaps increase the 'possibility' of aggregation increase, it ignores the fact that networks are laid out w/ wires and planned logically wrt tariff issues and existing infrastructure and capacity. While it's a good idea, it's not terribly practically useful. For example, we cover 11 states, so would I then need 11 CIDR blocks? Why not do things "right" and let me have 2 CIDR blocks to downlay from my 2 hubs. If customers want to change ISPs, that's not my/our concern, DHCP, bootp, manual renumbering are all available. -alan
