Draft Policy ARIN-2019-21: Reserved Pool Replenishment

Problem Statement:

While the current level of resources in the reserve pools created in 
Sections 4.4 and 4.10 presently seem more than adequate for their 
intended purposes. Nevertheless, even these well-resourced pools will 
eventually run out. Therefore, we should make arrangements for their 
replenishment, if or when necessary.

Policy Statement:

Add a new subsection in IPv4 General Principles, Section 4.1;

4.1.X Reserved Pool Replenishment

4.1.X.1 Disposition of Resources

Any resources allocated from a reserved pool created in Sections 4.4 or 
4.10, or any other reserved pools created in the future, that become 
available for re-issuance will be returned to the reserved pool they 
were originally allocated from, regardless of the current level of each 
pool. Further, any other resources which become available for 
re-issuance will be prioritized for the replenishment of any reserved 
pool that falls below a running three-year supply, which is based on the 
previous three years of allocations from each pool.

4.1.X.2 Precedence for Replenishment

Staff shall return groups of blocks to the pools in scheduled batches 
(staff shall set a reasonable schedule). Each available block in a batch 
shall be retruend in order from largest to smallest to the pool which at 
that point has the lowest percentage of a 3-year supply for that 
particular pool.

Timetable for Implementation: Upon Passage

Anything Else:

ARIN Staff should regularly report on the levels and projected run-times 
for each reserved pool and immediately report when any reserved pool 
falls below a three-year running supply.

A three-year running supply was chosen to provide the ARIN Policy 
Community adequate time to react through policy, as deemed appropriate 
at that time, to an imminent run out event for one of the reserved pools.
