<h3>Purpose of this document</h3>
<p>This document provides a background report on the progress of an
active Global Policy proposal, "Global Policy Proposal for Post
Exhaustion IPv4 Allocation Mechanisms by IANA". It is intended as a
background briefing for the ICANN Board and the wider community. </p>
<h3>Introduction</h3>
<p>Global Internet Number Resource Policies are defined by the <a href="http://www.icann.org/en/aso/aso-mou-29oct04.htm">ASO MOU</a>
- between ICANN and the NRO - as "Internet number resource policies
that have the agreement of all RIRs according to their policy
development processes and ICANN, and require specific actions or
outcomes on the part of IANA or any other external ICANN-related body in
order to be implemented". Attachment A of this MOU describes the
Development Process of Global Internet Number Resource Policies,
including the adoption by every RIR of a global policy to be forwarded
to the ICANN Board by the ASO<sup><a href="http://www.icann.org/en/announcements/announcement-26apr11-en.htm#foot1">1</a></sup><a name="text1" id="text1"></a>, as well as its ratification by the ICANN Board. In this context, the ICANN Board adopted its own <a href="http://www.icann.org/en/general/review-procedures-pgp.html">Procedures</a> for the Review of Internet Number Resource Policies Forwarded by the ASO for Ratification.</p>
<p>Among other features, these Procedures state that the Board will
decide, as and when appropriate, that ICANN staff should follow the
development of a particular global policy, undertaking an "early
awareness" tracking of proposals in the addressing community. To this
end, staff should issue background reports periodically, forwarded to
the Board, to all ICANN Supporting Organizations and Advisory Committees
and posted at the ICANN web site.</p>
<p>At its meeting on 21 April 2011, the Board resolved to request
tracking of the development of a "Global Policy for post exhaustion IPv4
allocation mechanisms by the IANA", under discussion in the addressing
community. The status overview presented below is compiled in response
to this request and will be further updated as developments proceed, for
information to ICANN entities and the wider community. This is the
third background report on this proposal. </p>
<h3>Status Overview</h3>
<p>The purpose of the proposal is to enable IANA to allocate returned
IPv4 blocks to RIRs. IANA would place IPv4 blocks returned by the RIRs
in a Recovered IPv4 Pool. This Pool would be declared active when one
RIR has less than half its last /8 left. IANA would then allocate an
"IPv4 allocation unit" (minimum size /24) to each RIR, if the Pool size
so permits. If the space available in the Pool is too limited,
allocation would be deferred in 6 month intervals until space is
available. </p>
<p>Following list discussions over slightly different drafts early in
2011, the current version of this global policy proposal was first
formally introduced in the APNIC region on 20 February 2011 and has
since been introduced and advanced in all the other RIRs. The proposal
has been adopted in APNIC, LACNIC and RIPE and has passed final call in
AfriNIC and ARIN.</p>
<h3>Process history</h3>
<p>On 3 February 2011, the ASO AC<sup><a href="http://www.icann.org/en/announcements/announcement-26apr11-en.htm#foot2">2</a></sup><a name="text2" id="text2"></a> recognized the proposal as fulfilling the formal requirements as a candidate for a Global Policy.</p>
<p>Once the proposal has been adopted in all RIRs, i.e. AfriNIC, APNIC,
ARIN, LACNIC and RIPE, the proposal will be handled by the NRO EC<sup><a href="http://www.icann.org/en/announcements/announcement-26apr11-en.htm#foot3">3</a></sup><a name="text3" id="text3"></a> and the ASO AC according to their procedures before being submitted to the ICANN Board for ratification.</p>
<p>As a background to this policy proposal, it should be noted that a
previous proposal for handling recovered IPv4 address space, "Global
Policy Proposal for the Allocation of IPv4 Blocks to Regional Internet
Registries" was introduced in 2009 but abandoned by the NRO EC in view
of version differences across the RIRs. For more information on that
proposal, see the corresponding <a href="http://www.icann.org/en/announcements/announcement-12may09-en.htm">background report</a>. That proposal is denoted as the <u>first</u> proposal in the table below.</p>
<p>Also, a second proposal on this theme "Global Policy Proposal for the
Allocation of IPv4 by IANA Post Exhaustion" was introduced in 2010.
This proposal was rapidly adopted in ARIN, but abandoned in APNIC and
withdrawn in RIPE, making it unlikely that the proposal would advance to
become a global policy. For more information on that proposal, see the
corresponding <a href="http://www.icann.org/en/announcements/announcement-11feb11-en.htm">background report</a>. That proposal is denoted as the <u>second</u> proposal in the table below.</p>
<p>The proposal that is the object of the current background report - for direct access to the proposal text click <a href="http://www.apnic.net/policy/proposals/prop-097/prop-097-v002.txt">here</a> [TXT, 12 KB] – is denoted as the <u>third</u> proposal in the table below, where the significant differences between the proposals are summarized.</p>
