Address clustering intuition

......... 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

If customers want to change ISPs, that's not my/our concern, DHCP,
bootp, manual renumbering are all available.


I don't see that this is relevant. If I call PacBell in San Jose,
it's a 408 number. In San Francisco, it's a 415 number. What does
this have to do with wires etc? The point is that every telephone
company knows where 408 is and how to route traffic to it.
