Draft Policy ARIN-2019-21: Reserved Pool Replenishment
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.
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
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.
