[arin-ppml] Policy Proposal: Predictable IPv4 Run Out by Allocation Window
ARIN received the following policy proposal and is posting it to the
Public Policy Mailing List (PPML) in accordance with Policy Development
This proposal is in the first stage of the Policy Development Process.
ARIN staff will perform the Clarity and Understanding step. Staff does
not evaluate the proposal at this time, their goal is to make sure that
they understand the proposal and believe the community will as well.
Staff will report their results to the ARIN Advisory Council (AC) within
The AC will review the proposal at their next regularly scheduled
meeting (if the period before the next regularly scheduled meeting is
less than 10 days, then the period may be extended to the subsequent
regularly scheduled meeting). The AC will decide how to utilize the
proposal and announce the decision to the PPML.
In the meantime, the AC invites everyone to comment on the proposal on
the PPML, particularly their support or non-support and the reasoning
behind their opinion. Such participation contributes to a thorough
vetting and provides important guidance to the AC in their deliberations.

During the ARIN XXIII policy discussion several individuals
described ideas similar to RIPE policy proposal 2009-03
This policy adapts the same idea into an ARIN policy for
discussion in this region.
From the RIPE proposal:
] This is a proposal to gradually reduce the allocation and assignment
] periods in step with the expected life time of the IPv4 unallocated
] pool in order to address the perception of unfairness once the pool
] has run out.
] The proposal is not intended to stretch the lifetime of the
] unallocated pool.
] The proposal is independent of other proposals to reserve address
] space for transition purposes and/or new entrants. It can be
] implemented independently of these.
