        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.
This turns out not to be the case at all. See the big-internet archives for lots of messages on this. --asp@uunet.uu.net (Andrew Partan)
