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

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 are 
returned, reclaimed, or revoked will be returned to the reserved pool 
they were originally allocated from, regardless of the current level of 
each pool. Further, any other resources returned, reclaimed, or revoked 
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.

Timetable for Implementation: Immediate

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.
