Once people realize that there's no more free v4 space to be had, or

Boston that's sitting on a /8. If the price for a clean /12 turns out
to be $5M, which I don't think is implausible, it'll be mighty tempting
for them to renumber into one /12 and sell off the others for a quick
There is a lot of speculation what IPv4 addresses are worth, I've been
hearing everything from a few USD to 20 EUR per address.
If it's 20 EUR per address, then I agree with you that there will be a lot
of addresses available for sale because it'll now all of a sudden be
worthwile to renumber, start using IPv6 with NAT64, or something else, and
get rid of your now excess IPv4 addresses. Most organisations will
probably be able to do this with costs ranging in 0.1 - a few million
I like this because it makes the incentive to move to IPv6 so much higher.
IPv4 is a dead end, the stone is bled dry, the earlier people realise this
and move on, the better.
I entirely realize that the sound of people yelling that it's totally
unfair that other people got their space for free and now they have to
pay will be deafening. Too bad. Back in the early 90s I missed the
cutoff to get my own unjustified /24 by about six months, but I've been
able to deal with it.
If there is no upside for people holding addresses to spend time/money to
free them up, these addresses won't get freed up and transferred.
