Recommended ARIN-2019-21: Reserved Pool Replenishment
AC Assessment of Conformance with the Principles of Internet Number
Draft policy 2019-21 enables fair number resource policy and is
technically sound. It has the apparent support of the community.
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
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
Timetable for Implementation: Upon Passage
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.
