Version: 2
Date: 21 December 2010
1. Introduction
- ----------------
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.
2. 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
3. Summary of the current problem
- ----------------------------------
With the depletion of the IANA free pool of IPv4 address space, the
current policy regarding the allocation of IPv4 address space to the
RIRs will become moot. The RIRs may, according to their individual
policies and procedures, recover IPv4 address space. This policy
provides a mechanism for the RIRs to retro allocate the recovered IPv4
address space to the IANA and provides the IANA the policy by which it
can allocate it back to the RIRs on a needs basis. This policy creates a
new global pool of IPv4 address space that can be allocated where it is
needed on a global basis without a transfer of address space between the
RIRs.
This policy proposal addresses the issues raised with the previous
policy proposal prop-069, which the authors agree will not gain
global consensus without significant revision.
4. Situation in other RIRs
- ---------------------------
This proposal is being submitted in all RIR regions, with a view to
becoming a global policy [1].

5. Details
- -----------
5.1 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.
5.2 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 RIRs unless they are being
returned by the RIR that they were orignally allocated to. Legacy
address holders may return address space directly to the IANA if
they so choose.
5.3 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 RIRs. Any
remainder not evenly divisible by the number of eligible RIRs 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.
5.4 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. An RIR is considered at exhaustion
when the inventory is less than the equivalent of a single /8 and is
unable to further allocate or assign address space to its customers
in units equal to or shorter than the longest of that 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.
5.5 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 5.4.
5.6 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.
5. Pros/Cons
- -------------
5.1 Advantages
- The policy provides a mechanism for the ongoing distribution of
IPv4 address space.
5.2 Disadvantages
- None identified.
6. Effect on APNIC Members
- ---------------------------
This policy governs the allocation relationship between the IANA and
the RIRs. It does not imply any change to allocation relationships
between APNIC and its members.
7. Effect on NIRs
- ------------------
This policy governs the allocation relationship between the IANA and
the RIRs. It does not imply any change to allocation relationships
between APNIC and NIRs.
