On 23 August 2007, the ARIN Advisory Council (AC) concluded their
initial review of "Legacy Outreach and Partial Reclamation" and accepted
it as a formal policy proposal for discussion by the community.

The AC accepted this proposal as written. The AC believes that further
edits would clarify the proposal and enhance the chance of community
consensus, and will be contacting the author with their suggestions
within the next week. The Advisory Council recommends the author
consider these changes, and submit them to policy at arin.net no later than
17 September 2007, which is suggested as a deadline for revisions for
the upcoming public policy meeting.

The proposal is designated Policy Proposal 2007-17: Legacy Outreach and
Partial Reclamation. The proposal text is below and can be found at:

All persons in the community are encouraged to discuss Policy Proposal
2007-17 prior to it being presented at the ARIN Public Policy Meeting in
Albuquerque, New Mexico, 17-18 October 2007. Both the discussion on the
Public Policy Mailing List and at the Public Policy Meeting will be used
to determine the community consensus regarding this policy proposal.

Policy Proposal 2007-17
Legacy Outreach and Partial Reclamation

Author: Owen DeLong

Proposal type: modify

Policy term: permanent

Policy statement:

Modify section 4.6 as follows:

4.6 Amnesty Requests ARIN will accept the return or relinquishment of
any address space from any existing address holder. If the address
holder wishes to aggregate into a single block, ARIN may work with the
address holder to arrive at an allocation or assignment which is equal
to or smaller than the sum of their existing blocks and which best meets
the needs of the existing holder and the community. There shall be no
fee for returning addresses under this policy. Further, organizations
returning addresses under this policy shall receive the following benefits:

1. If the organization does not currently pay ARIN fees, they shall
remain fee exempt.

2. If the organization currently pays ARIN fees, their fees shall be
waived for two years for each /20 equivalent returned, with any
fractional /20 equivalent resulting in a one-time single year waiver.

3. Any organization returning address space under this policy shall
continue under their existing RSA or they may choose to sign the current
RSA. For organizations which currently do not have an RSA, they may sign
the current RSA, or, they may choose to remain without an RSA.

4. All organizations returning space under this policy shall, if they
meet other eligibility requirements and so request, obtain an
appropriate IPv6 end-user assignment or ISP allocation as applicable,
with no fees for the first 5 years. Organizations electing to receive
IPv6 allocation/assignment under this provision must sign a current RSA
and must agree that all of their IPv4 resources are henceforth subject
to the RSA. Organizations taking this election shall be subject to
end-user fees for their IPv4 resources not previously under an ARIN RSA.
If they are already an ARIN subscriber, then IPv4 resources affected by
this process may, instead, be added to their existing subscriber
agreement at the address holder's discretion.


The current amnesty policy does a nice job of facilitating aggregation,
which was the intent when it was drafted. However, as we approach IPv4
free-space exhaustion, the community now has an additional need to
facilitate address reclamation.

A very high percentage of underutilized space is in the hands of legacy
holders who currently have no benefit to joining the ARIN process.
Further, there is an unfortunate perception that doing so will require
force the legacy holder into certain future disadvantages. This proposal
attempts to resolve both of those issues while also providing some
incentive to legacy organizations to start using IPv6 resources and
bring their IPv4 resources into the ARIN process.

This policy attempts to provide some benefit and remove most of the
costs of making partial IPv4 returns. It also attempts to provide an
incentive for these IPv4 holders to join the ARIN process.

Timetable for implementation: Immediate
