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
10 days.

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.

Policy Proposal 101: Multihomed initial allocation criteria

Proposal Originator: Chris Grundemann

Proposal Version: 1

Date: 30 October 2009

Proposal type: modify

Policy term: permanent

Policy statement:

Modify item number 4 under section Initial allocation criteria
to the following:

4. be an existing, known ISP in the ARIN region or have a plan for
making at least 200 end-site assignments to other organizations within
5 years or, if multihomed, demonstrate the efficient utilization of a
minimum contiguous or noncontiguous /44 (sixteen /48s) from an


The bar for obtaining initial IPv4 allocations is lower for those ISPs
which are multi-homed, it stands to reason that it also be lower in
IPv6.  Since efficient utilization is based on the use of /48s, this
policy would effectively allow any ISP with 15 active customers (with
one /48 each and one /48 for the ISPs own network) to receive an initial
allocation of an IPv6 /32 from ARIN. I think this is a better approach
than removing or lowering the end-site assignment requirement for _all_
ISPs while still providing more open access to IPv6.

Timetable for implementation: immediate
