Draft Policy 2010-10 (Global Proposal)
Global Policy for IPv4 Allocations by the IANA Post Exhaustion

On 15 July 2010 the ARIN Advisory Council (AC) selected "Global Policy
for IPv4 Allocations by the IANA Post Exhaustion" as a draft policy for
adoption discussion on the PPML and at the Public Policy Meeting in
Atlanta in October.

The draft was developed by the AC from policy proposal "115. Global
Policy for IPv4 Allocations by the IANA Post Exhaustion". Per the Policy
Development Process the AC submitted text to ARIN for a staff and legal
assessment prior to its selection as a draft policy. After receiving the
assessment the text was revised. Below the draft policy is the ARIN
staff and legal assessment, followed by the text that was submitted by
the AC.

Draft Policy 2010-10 is below and can be found at:
https://www.arin.net/policy/proposals/2010_10.html

You are encouraged to discuss Draft Policy 2010-10 on the PPML prior to
the October Public Policy Meeting. Both the discussion on the list and
at the meeting will be used by the ARIN Advisory Council to determine
the community consensus for adopting this as policy.

Draft Policy 2010-10 (Global Proposal)
Global Policy for IPv4 Allocations by the IANA Post Exhaustion

Version/Date: 20 July 2010

Policy statement:

1. Reclamation Pool Upon adoption of this IPv4 address policy by the
ICANN Board of Directors, the IANA shall establish a Reclamation Pool to
be utilized post RIR IPv4 exhaustion as defined in Section 4. The
reclamation pool will initially contain any fragments that may be left
over in IANA inventory. As soon as the first RIR exhausts its inventory
of IP address space, this Reclamation Pool will be declared active. When
the Reclamation Pool is declared active, the Global Policy for the
Allocation of the Remaining IPv4 Address Space[3] and Policy for
Allocation of IPv4 Blocks to Regional Internet Registries[4] will be
formally deprecated.

2. Returning Address Space to the IANA The IANA will accept into the
Reclamation Pool all eligible IPv4 address space that are offered for
return. Eligible address space includes addresses that are not
designated as "special use" by an IETF RFC or addresses allocated to
RIR's unless they are being returned by the RIR that they were originally
allocated to. Legacy address holders may return address space directly
to the IANA if they so choose.

3. Address Allocations from the Reclamation Pool by the IANA Allocations
from the Reclamation Pool may begin once the pool is declared active.
Addresses in the Reclamation Pool will be allocated on a CIDR boundary
equal to or shorter than the longest minimum allocation unit of all RIRs
in order to complete these allocations.The Reclamation Pool will be
divided on CIDR boundaries and distributed evenly to all eligible RIR's.
Any remainder not evenly divisible by the number of eligible RIR's based
on a CIDR boundary equal to or shorter than the longest minimum
allocation unit of all RIRs will remain in the Reclamation Pool.
Addresses that are left over will be held in the Reclamation Pool until
additional IP addresses can be returned to rejoin addresses on CIDR
boundaries to the Reclamation Pool or a minimum allocation unit is set
to allow allocation from existing inventory.

4. RIR Eligibility for Receiving Allocations from the Reclamation Pool
Upon the exhaustion of an RIR's free space pool and after receiving
their final /8 from the IANA[3], an RIR will become eligible to request
address space from the IANA Reclamation Pool when it publicly announces
via its respective global announcements email list and by posting a
notice on its website that it has exhausted its supply of IPv4 address
space. Exhaustion is defined as an inventory of less than the equivalent
of a single /8 and the inability to further assign address space to its
customers in units equal to or shorter than the longest of any RIR's
policy defined minimum allocation unit. Any RIR that is formed after the
ICANN Board of Directors has ratified this policy is not eligible to
utilize this policy to obtain IPv4 address space from the IANA.

5. Reporting Requirements The IANA shall publish on at least a weekly
basis a report that is publicly available which at a minimum details all
address space that has been received and that has been allocated. The
IANA shall publish a Returned Address Space Report which indicates what
resources were returned, by whom and when. The IANA shall publish an
Allocations Report on at least a weekly basis which at a minimum
indicates what IPv4 address space has been allocated, which RIR received
the allocation and when. The IANA shall publish a public notice
confirming RIR eligibility subsequent to Section 4.

6. No Transfer Rights Address space assigned from the Reclamation Pool
may be transferred if there is either an ICANN Board ratified global
policy or globally coordinated RIR policy specifically written to deal
with transfers whether inter-RIR or from one entity to another.
Transfers must meet the requirements of such a policy. In the absence of
such a policy, no transfers of any kind related to address space
allocated or assigned from the reclamation pool is allowed.

7. Definitions

IANA - Internet Assigned Numbers Authority, or its successor

ICANN - Internet Corporation for Assigned Names and Numbers, or its
successor

RIR - Regional Internet Registry as recognized by ICANN

MOU - Memorandum of Understanding between ICANN and the RIRs

IPv4 - Internet Protocol Version Four(4), the target protocol of this
Global Policy

Free Space Pool - IPv4 Addresses that are in inventory at any RIR,
and/or the IANA

STAFF ASSESSMENT

Proposal: (115) Global Policy for IPv4 Allocations by the IANA Post
Exhaustion
Proposal Version (Date): 01 July 2010
Date of Assessment:  14 July 2010

1. Proposal Summary (Staff Understanding)

This policy establishes an IANA reclamation pool of IPv4 address space.
  This pool will be comprised of any “eligible” IPv4 address space
returned to IANA. Once the pool is activated, the two existing IPv4
Global policies (NRPM policies 10.1 and 10.4) will be formally retired.
RIRs may request addresses from this pool upon exhaustion of their IPv4
inventory, as defined in the policy. The policy further requires IANA to
do weekly reporting on the address pool. The policy prohibits any
transfers of the address space issued from the reclamation pool.

2. Comments

A. ARIN Staff Comments

•  Should the retirement of existing 10.1 and 10.4 policies occur right
after the triggering of 10.4, since the triggering of 10.4 will occur
before any RIR suffers depletion?
•  Does the reclamation pool begin with all IANA number resource
remnants dumped into it?  Or is it only returns after the date of the
pool beginning?
•  Why does the last sentence of paragraph 4 exclude late-formed RIRs?
•  The proposal defines RIR exhaustion as “an inventory of less
than the equivalent of a single /8 and the inability to further assign
address space to its customers in units equal to or shorter than the
longest of the RIR's policy defined minimum allocation unit.”   For
clarification, staff interprets this definition to mean that exhaustion
occurs at the point when ARIN has less than a /8 and no /24s (per policy
2010-2) available to issue.
•  Section 3 of the policy says that the reclamation pool will be
“divided and distributed evenly to all eligible RIRs”.   However, it
appears that any RIR can request additional address space from the
reclamation pool at any point in time when they have exhausted their
IPv4 inventory.  Because this will occur at different times for each
RIR, staff does not understand how the pool will be distributed evenly
amongst the 5 RIRs.
•  The first sentence says “post-RIR IPv4 exhaustion as defined in
section 5”, however, the definition is actually contained in section 4.

3. Resource Impact

This policy would have minimal resource impact.  It is estimated that
implementation would occur within 3 months after ratification by the
ARIN Board of Trustees. The following would be needed in order to implement:
•  Updated guidelines
•  Staff training

4. Proposal Text
Policy statement:
1. Reclamation Pool
Upon adoption of this IPv4 address policy by the ICANN Board of
Directors, the IANA shall establish a Reclamation Pool to be utilized
post RIR IPv4 exhaustion as defined in Section 5. As soon as the first
RIR exhausts its inventory of IP address space, this Reclamation Pool
will be declared active. When the Reclamation Pool is declared active,
the Global Policy for the Allocation of the Remaining IPv4 Address
Space[3] and Policy for Allocation of IPv4 Blocks to Regional Internet
Registries[4] will be formally deprecated.
2. Returning Address Space to the IANA
The IANA will accept into the Reclamation Pool all eligible IPv4 address
space that are offered for return. Eligible address space includes
addresses that are not designated as "special use" by an IETF RFC or
addresses allocated to RIR's unless they are being returned by the RIR
that they were originally allocated to. Legacy address holders may
return address space directly to the IANA if they so choose.
3. Address Allocations from the Reclamation Pool by the IANA
Allocations from the Reclamation Pool may begin once the pool is
declared active. Addresses in the Reclamation Pool will be allocated on
a CIDR boundary equal to or shorter than the longest minimum allocation
unit of all RIRs in order to complete these allocations.The Reclamation
Pool will be divided on CIDR boundaries and distributed evenly to all
eligible RIR's. Any remainder not evenly divisible by the number of
eligible RIR's based on a CIDR boundary equal to or shorter than the
longest minimum allocation unit of all RIRs will remain in the
Reclamation Pool. Addresses that are left over will be held in the
Reclamation Pool until additional IP addresses can be returned to rejoin
addresses on CIDR boundaries to the Reclamation Pool or a minumum
allocation unit is set to allow allocation from existing inventory.
4. RIR Eligibility for Receiving Allocations from the Reclamation Pool
Upon the exhaustion of an RIR's free space pool, an RIR will become
eligible to request address space from the IANA Reclamation Pool when it
publicly announces via its respective global announcements email list
and by posting a notice on its website that it has exhausted its supply
of IPv4 address space. Exhaustion is defined as an inventory of less
than the equivalent of a single /8 and the inability to further assign
address space to its customers in units equal to or shorter than the
longest of the RIR's policy defined minimum allocation unit. Any RIR
that is formed after the ICANN Board of Directors has ratified this
policy is not eligible to utilize this policy to obtain IPv4 address
space from the IANA.
5. Reporting Requirements
The IANA shall publish on at least a weekly basis a report that is
publicly available which at a minimum details all address space that has
been received and that has been allocated. The IANA shall publish a
Returned Address Space Report which indicates what resources were
returned, by whom and when. The IANA shall publish an Allocations Report
on at least a weekly basis which at a minimum indicates what IPv4
address space has been allocated, which RIR received the allocation and
when. The IANA shall publish a public notice confirming RIR eligibility
subsequent to Section 4.
6. No Transfer Rights
Address space assigned from the Reclamation Pool may be transferred if
there is either an ICANN Board ratified global policy or globally
coordinated RIR policy specifically written to deal with transfers
whether inter-RIR or from one entity to another. Transfers must meet the
requirements of such a policy. In the absence of such a policy, no
transfers of any kind related to address space allocated or assigned
from the reclamation pool is allowed.
7. Definitions
IANA - Internet Assigned Numbers Authority, or its successor
ICANN - Internet Corporation for Assigned Names and Numbers, or its
successor
RIR - Regional Internet Registry as recognized by ICANN
MOU - Memorandum of Understanding between ICANN and the RIRs
IPv4 - Internet Protocol Version Four(4), the target protocol of this
Global Policy
Free Space Pool - IPv4 Addresses that are in inventory at any RIR,
and/or the IANA
Rationale:
This policy defines the process for the allocation of IPv4 addresses
post "Exhaustion Phase"[1]. A global policy is required in order for the
IANA to be able to transparently continue to be able to allocate IPv4
addresses beyond exhaustion. In order to fulfill the requirements of
this policy, the IANA must set up a reclamation pool to hold addresses
in and distribute from in compliance with this policy. This policy
establishes the process by which IPv4 addresses can be returned to and
re-issued from the IANA post Exhaustion Phase.
This document does not stipulate performance requirements in the
provision of services by the IANA to an RIR in accordance with this
policy. Such requirements should be specified by appropriate agreements
among the RIRs and ICANN.
The intent of this policy is as follows:
*  To include all post Exhaustion Phase IPv4 address space returned to
the IANA.
*  Allows allocations by the IANA from the Reclamation Pool once the
Exhaustion Phase has been completed.
*  Defines "need" as the basis for further IPv4 allocations by the IANA.
*  Does not differentiate any class of IPv4 address space unless
otherwise defined by an RFC.
*  Encourage the return of IPv4 address space by making this allocation
process available.
*  Disallow transfers of addresses sourced from the Reclamation Pool in
the absence of an IPv4 Global Transfer Policy to neutralize transfer
process inequities across RIR regions.
*  Applies to legacy IPv4 Address Space initially allocated by the IANA
to users including the allocations to RIRs.
*  Includes any length of fragments currently held by the IANA now or in
the future.
