Thus spake <Michael.Dillon@btradianz.com>
Let's face it, IPv6 is close enough to IPv4 that any attempt to put a price on IPv4 addresses will simply cause a massive migration to free and plentiful IPv6 addresses.
You assume that there will be a source of free and plentiful IPv6 addresses. AFAIK, none of them are rent-free, and they're not even available unless you have the clue and resources to prented to be an LIR. So, unless there's policy change, most end-user orgs will have no choice but to pay the market rate for IPv4 addresses. Spot markets are good when demand is elastic, but we're faced with a market that has growing inelastic demand that will outstrip fixed supply in a decade. Capitalism doesn't handle that well.
