Dear Colleagues;

Please accept the following as our update with respect to the presentation
that we had made at the AfriNIC in Johannesburg.

Also, thank you for your help and hospitality during that meeting and I hope
to see you all in Dar el Salam.


----TEXT UPDATE



Policy Proposal Name: Global Policy for IPv4 Allocation by the IANA post
exhaustion

UPDATED TEXT
 
Policy Text 


New:

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 must be allocated on a CIDR
boundary. Allocations from the Reclamation Pool are subject to a minimum
allocation unit equal to the minimum allocation unit of all RIRs and a
maximum allocation unit of one /8. The Reclamation Pool will be divided on
CIDR boundaries and distributed evenly to all eligible RIRs once each
quarter. Any remainder not evenly divisible by the number of eligible RIRs
will remain in the Reclamation Pool until such time sufficient address
returns allow another round of allocations.

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. Up to one /10 or equivalent of IPv4 address
space specifically reserved for any special purpose by an RIR will not be
counted against that RIR when determining eligibility unless that space was
received from the IANA reclamation pool. 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. 

Arguments supporting the proposal

Currently, no method for the IANA to allocate IPv4 address space that
may be returned to it by legacy address holders or others exists. This
proposal attempts to establish a process to insure that it is possible
for the IANA to allocate such IPv4 address space.

Arguments opposing the proposal

To date, no known objections.
