ARIN received the following policy proposal. In accordance with the ARIN
Internet Resource Policy Evaluation Process, the proposal is being
posted to the ARIN Public Policy Mailing List (PPML) and being placed on
ARIN's website.

The ARIN Advisory Council (AC) will review this proposal at their next
regularly scheduled meeting. The AC may decide to:

     1. Accept the proposal as written. If the AC accepts the proposal,
it will be posted as a formal policy proposal to PPML and it will be
presented at a Public Policy Meeting.

     2. Not accept the proposal. If the AC does not accept the proposal,
the AC will explain their decision via the PPML. If a proposal is not
accepted, then the author may elect to use the petition process to
advance their proposal. If the author elects not to petition or the
petition fails, then the proposal will be closed.

The AC will assign shepherds in the near future. ARIN will provide the
names of the shepherds to the community via the PPML.

In the meantime, the AC invites everyone to comment on this 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 Name:  Emergency Transfer Policy for IPv4 Addresses

Author: Bill Darte

Proposal Version: 1.0

Submission Date:  August 15, 2008

Proposal type: New

Policy term:  Temporary

Policy statement:

8.2.1 Emergency Transfer Policy for IPv4 Addresses

For a period of 3 years from policy implementation, transfer of ARIN
IPv4 addresses between two entities in the ARIN region, without the
active involvement of ARIN as an intermediary, will be considered
legitimate and will be documented accordingly under the following

1.  Transfer takes place from a holder of IPv4 addresses recognized by
ARIN as the legitimate and exclusive holder of those resources.

2.  Transfer takes place to a recipient that has documented operational
need in accordance with current ARIN policy and that signs an RSA with
ARIN covering those resources in advance of transfer.

3.  Transfer of addresses takes place in such a way that the original
contiguous block(s) are not disaggregated into more than 4 resultant
network blocks each being greater than or equal to the current minimum
sizes specified in applicable ARIN policy.

4.  Transfer is complete and unrestricted and is supported by
documentation that ARIN deems satisfactory.


In order for ARIN to fulfill its mission and to facilitate a continuing
supply of IPv4 address resources to its service community when ARIN
resources are no longer adequate, and to preserve the integrity of
documentation and ARIN services for those resources, this policy may be
implemented.  Its intent is to preserve the current tradition of
need-based allocation/assignments for those still needing IPv4 resources
during a transition period as the industry adopts IPv6. This policy is
not intended to create a 'market' for such transfers and does not
introduce or condone the monetization of address resources or a view of
addresses as property.  It does recognize that organizations making
available unused or no longer needed address resources may incur certain
costs that might be compensated by those acquiring the resources.  This
policy is intended to be transient and light-weight and does not
encourage a sustained or continuing role for IPv4, but rather helps to
mitigate a transitional crisis that may emerge while the industry adopts
IPv6 in accordance with the recommendation of ARIN's Board of Trustees.

Timetable for implementation:

This policy, once ratified by the ARIN Board of Trustees, would be
implemented when either the free-pool of IANA addresses is exhausted or
IPv4 address resources in the ARIN Region reaches a threshold of
scarcity recognized  by the ARIN Board of Trustees as requiring this
policy implementation.
