Not that I disagree, but what will be the impact of the IPv4 commodity
market in relationship to the routing table and the concepts of good IPv4
First off, it is likely that those with large amounts of legacy will sell
off small unused chunks of that space. "So you need a /22 to turn up a
new customer, and I've got this legacy Class B. I could sell you the .26,
.113, .117, and .118 subnets."
This results in de-aggegragtion and many more specific in the routing
This also makes the only justification for IP space how much money you
have. This means poor companies (or countries) may be left out in the
cold increasing the digital divide, and spinning up the efforts of
WSIS and the UN. It is also possible that rich companys might stockpile
the remaining addesses. What would happen if say Cogent bought up all of
the remaining space? Can you see other ISPs hanging out the "no address
vacancy, please try Cogent" sign?
