on the other side of the pond, the Euros are grappling with a desire to get actual utilization of assigned numbers into something above single digits. They are shooting for 80% utilization of all assets before assigning any additional numbers. this problem has been around for a -very- long time, predating the RIRs by a couple of decades. the gist is, virtually -every- allocation/delegation exceeds the actual demand - sometimes by many orders of magnitude. in the IPv4 space, it was common to have a min allocation size of a /20 ... or 4,096 addresses ... and yet this amnt of space was allocated to someone who only needed to address "3 servers"... say six total out of a pool of four thousand ninty six. Thats a huge amnt of wasted space. If our wise and pragmatic leaders (drc, jc, et.al.) are correct, then IPv4 will be around for a very long time. What, if any, plan exists to improve the utilization density of the existant IPv4 pool? --bill
