Policy Proposal 114: RFC1918 as initial ISP multihomed criteria

[Member Services]

ARIN received the following policy proposal and is posting it to the
Public Policy Mailing List (PPML) in accordance with Policy Development
Process.

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 114: RFC1918 as initial ISP multihomed criteria

Proposal Originator: Steve Bertrand

Proposal Version: 1

Date: 7 May 2010

Proposal type: Modify

Policy term: Permanent

Policy statement:

Append the following statement to the end of all three criteria under
4.2.2.2:

", or the equivalent number of addresses within RFC 1918 space."

Rationale:

There are times when I've come across an ISP network in which either
their, or one of their ISP clients access networks will fit the 4.2.2.2
requirements based on addresses, but they utilize RFC 1918 space with
numerous layers of NAT, with only a very small block of public address
space from their upstream(s).

In that case, to qualify under the multi-homed policy, the ISP (and/or
its clients) would first have to renumber out of the private space into
an upstream space, and then renumber again after receiving the
allocation from ARIN.

This brief amendment would alleviate the double renumbering, and
conserve the human resources required by all parties involved.

Although I've considered ideas on how the use of RFC 1918 space could be
justified to ARIN, I feel that this could be hashed out on the list if
the intent of the proposal is accepted by the community.

Timetable for implementation: immediate
