Policy Statement on Address Space Allocations

I have a concern about tying any kind of fee to address allocations. If we
do that, we are essentially leasing addresses and we have no way to deal
with address speculation.
There is no way we could prevent arbitrage, scalping, speculation and
hoarding, no matter how high the fees are set.

Better to stay away from fees and leave open options with respect to allocation.

That's not to say that we could have charges for routing table entries,
although no one has suggested a formula for how to do that or predict the
total costs.
