Easy problem to solve, so many entire /8 blocks are owned by single corporations, which should either be forced to sell or give up this outdated privilege. Does Xerox really need all of 13.x.x.x? Or Ford Motor Company all of 19.x.x.x?
Between 2008 and 2010, IANA was allocating 10 /8s per year. In 2010, they allocated 20 /8s. There are only 256 total in the system, and not all of those are even usable.
Rapidly-developing Asia already has about as many people as there are IP addresses by itself.
Where are you going to find enough /8s, how are you going to recover them fast enough to do any good, and who's going to pay the massive legal bills from the ensuing litigation?
They probably assign static IPs in their range all the time. They just aren't publicly routable. Taking away their /8 would require a huge amount of reconfiguration work, so not sure what the motive would be, until the prices get really high.
And how long will that last? And there's a presumption here that businesses with lots of IPs that got in early aren't already selling them for fun and profit. They, such as Nortel, already are.
