Recovering three-quarters of an /8 delays the moment of truth by less
than a month. Work hard and you might gain a year or even more, but
would that year really make a difference?
And that is why there will never be a market for IPv4 addresses. Any
trading activity can only ever buy a few months of time for the buyer.
After that, they have to migrate to IPv6 like everyone else. Eventually,
some companies will shut down IPv4 infrastructure and release IPv4
addresses, but that is only going to happen once IPv6 is well and truly
proven in their network. In order to shut off a network, 100% of the
traffic has to be shifted to a replacement infrastructure. How many of
you know of X.25 networks still in operation?
