Hi Owen,

The governing language is in NRPM 4.3.3 which reads:

    * A 25% immediate utilization rate, and
    * A 50% utilization rate within one year.

So that's 64 addresses now and an additional 64 within one year.
Except of course, nobody will check in a year to see if you used an
additional 64 addresses.

IMHO, 4.3.3 should probably be tightened up a bit as we approach free
pool depletion, perhaps to something like "50% now and 75% in a year"
or maybe just "50% now" since we probably aren't going to check in
with end-users in a year anyway. Allowing assignments at the /24 level
will help us do that since it would no longer have the effect of
putting the minimum assignment size out of reach for small multihomed
orgs in the "couple hundred people" category.

Concur. Also, I'd like to see whether any problems (e.g. fraud) crop
up at this proposal's level so that they can be corrected before
attempting for full parity with NRPM

I don't anticipate any problems. ARIN's IPv4 process remains arcane
enough to do a solid job keeping those without a genuine need at bay.
