Technologies like NAT and efforts to reclaim poorly assigned address space have a large negative pressure on the increase of IP utilization. As more and more "appliances" need IP addresses, people will realize more and more that the last thing they want is those "applicances" on public IP space.
Does anybody have statistics for assigned-but-not-announced space? I'd be willing to bet there will be more and more dead space over the years, and in fact quite a bit of "increasing usage" is just churn.
http://www.potaroo.net/ispcolumn/2003-07-v4-address-lifetime/ale.html This is actually a pretty good write-up about the IPv4 address lifetime by Geoff Huston. It has some graphs that compares BGP to actually assigned space comparisons. Makes very good reading about all this. -- Cliff Albert | RIPE: CA3348-RIPE | https://oisec.net/ cliff@oisec.net | 6BONE: CA2-6BONE | PGP Fingerprint = 9ED4 1372 5053 937E F59D B35F 06A1 CC43 9A9B 1C5A
