1. Where is the current demand for IPv4 coming from? Plenty of analysis here.

2. Can the new demand be steered towards IPv6 therefore slow down IPv4 depletion. For example in the developing world a lot of the demand is brand new and therefore can it be satisfied with IPv6? Of course incentives are in order though it's much easier than asking the behemoths to give up "their" /16s etc.
Well, you could give IPv6 instead of IPv4 but only if they can talk to the rest of the world over IPv6. So everyone who has IPv4 today would have to add IPv6, but if they were prepared to do that, running out of IPv4 space wouldn't be an issue in the first place. Also, who cares about /16s? We currently have 16848 /16s left and we're using up approximately 8 - 9 of them each day. Postponing the inevitable by 3 hours really isn't all that useful... Can we please finish off the remaining IPv4 address space already so we can get on with our lives?
