How many years?
Globally, about 12-13 /8s were assigned in 2008.

There are something like 40 "legacy" Class A assignments, but most of them are
in use.   How many do you think could be reallocated?
There are, what, 44 /8s assigned as 11,000 Class Bs?  Most of the Class Bs
are in use.  How many do you think could be reallocated?

What is the threshold for utilization?  Do we tell end user organizations that if 
they don't qualify for an additional allocation (80% utilization of current blocks
(NRPM 4.3.6)) they don't qualify for their current block?  Is 25% acceptable?
This is important in figuring out how many allocations could be recovered.

I think we could get an extra year out of IPv4 this way.  Maybe +/- six months.
How much should ARIN spend to do this?

That would be interesting.  Anybody want to do it?  


These aren't rhetorical questions, btw.  I'm sincerely looking for guidance from
the members as to how you want ARIN to spend its resources.

Thanks,
