Policy Proposal Name: Protective Usage Transfer Policy for IPv4 Address

Proposal Originator : Christopher A. Quesada

Proposal Version: 2

Date: 5 March 2009

Policy statement:

Critical infrastructure providers may appeal to ARIN for final review
and approval of any full or partial transfer of IPv4 address space that
has been in use by the critical infrastructure serving the community for
five consecutive years or more.  Such appeal may result in a partial or
full approval of the requested transfer, or rejection of the transfer if
it lacks appropriate rationale, justification, or interferes with the
seamless operation of such critical infrastructure or hardship to the

Protection of critical infrastructure providers of the Internet,
including public exchange points, core DNS service providers (e.g.
ICANN-sanctioned root, gTLD, and ccTLD operators) as well as the RIRs
and IANA 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
(as defined in ARIN’s Number Resource Policy Manual).  This policy is
intended to protect that critical infrastructure by allowing for the
review and final approval of such transfer by ARIN, upon appeal by the
critical infrastructure provider to ARIN, within a sixty day period of
the transfer notification if such transfer would interfere with the
continuous and seamless operation of that critical infrastructure or
hardship to the provider.  Review of the transfer can consist of a
request by ARIN to the transferring organization for a rationale for
such transfer.  This may include but not be limited to, a requirement
for the receiving party to submit the appropriate network request form
identifying the need and justification for the aggregate IPv4 address
