I don't believe it doesn't lead to significant conservation.
The point of this example was to make it self-adjusting. As the free
pool gets smaller, the restrictions increase automatically. By
definition, it would extend the free pool as far as it needs to go --
the restrictions would get arbitrarily complex so at some point it
becomes easier/cheaper/more cost effective to simply deploy IPv6 and
the NAT boxes necessary for IPv6-only sites to talk to the rest of
the Internet.
As far as I can tell, the difference between this and what is in the
IPv4 countdown proposal is there isn't an arbitrary flag day that
results in one day people being able to get IPv4 address space and
the next day not (regardless of their need or justification).
I'm sure there are many others.
Again, I don't think there are many.
There are a myriad variations and combinations that can be applied.
It would be very difficult to decide which portion of address blocks
that are currently allocated/assigned will not be allocated/assigned
in a new policy.
I must not understand this comment. I would assume the new policy
would apply to the free pool existent at the time the policy was
implemented, just like policies have always been applied.
