ARIN received the following policy proposal. In accordance with
the ARIN Policy Development Process, the proposal is being posted to the
ARIN Public Policy Mailing List (PPML).

This proposal is in the first stage of the ARIN Policy Development
Process. ARIN staff will perform the Clarity and Understanding step.
Staff does not evaluate the proposal itself at this time, their only aim
is to make sure that they understand the proposal and believe that the
community will as well. Staff will report the results of this step to
the ARIN Advisory Council (AC) within 10 days.

The AC will review this 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. The decision will be announced to 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: Protective Usage Transfer Policy for IPv4 Address

Proposal Originator : Christopher A Quesada,

Proposal Version: 1

Date: 2/9/2009

Proposal type: New

Policy term: permanent

Policy statement:

Protective Usage Transfer Policy for IPv4 Address

Critical infrastructure providers may appeal to ARIN for final review 
and decision of any full or partial transfer of IPv4 address space that 
has been in use serving the community for consecutive periods of time.


Protection of critical infrastructure as defined in ARIN’s Number 
Resource Policy Manual is necessary in order to ensure the continuous 
operation of the Internet for its global service community. It is 
possible for an organization to transfer an aggregate IPv4 address 
resource containing allocations/assignments downstream supporting 
critical infrastructure. This policy is intended to protect critical 
infrastructure by not allowing the transfer of those assignments if such 
transfer would interfere with the continuous and seamless operation of 
that critical infrastructure or hardship to the provider.

Timetable for implementation: immediately
