[LACNIC/Politicas] Global Policy for IPv4 Allocations by the IANA Post Exhaustion

[Chris Grundemann]

Hello LACNIC!

A group of folks and I have been working on a global policy proposal
regarding returning and re-allocating IPv4 addresses to and from the
IANA post IPv4 exhaustion. We have decided that the best approach is
to post the draft text publicly in each of the five regions and
request comments before officially submitting it as a global policy
proposal. In this way we hope to be able to address any gaps or other
problems early on, avoiding potential issues later in the process.

Your comments, on or off list, are welcome and appreciated. We are
collecting additional feedback until June 8, 2010 and possibly beyond,
depending upon the feedback.



# Global Policy for IPv4 Allocations by the IANA Post Exhaustion #

Global Policy for IPv4 Allocations by the IANA Post Exhaustion
Rationale:
This policy defines the process for the allocation of IPv4 addresses
post "Exhaustion Phase"[1]. 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.

The intent of this policy is as follows:
    * Includes all post Exhaustion Phase 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
defined by RFC 1918.
    * Encourages the return of IPv4 address space by making this
re-allocation process available.
    * Disallows 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.



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.

2. Returning Address Space to the IANA
The IANA will accept into the Reclamation Pool all eligible IPv4
address space that is offerred for return. Eligible address space
includes any addresses not previously designated for special use by an
IETF published RFC explicitly offerred for return to the IANA by:
a) The RIR to which the space is assigned
b) The registrant of record where no RIR holds authority

3. Address Allocations from the Reclamation Pool by the IANA
Allocations from the Reclamation Pool may begin once the pool is
declared active. Aggregates in the Reclamation Pool may be divided on
a CIDR boundary to the longest minimum allocation or assignment of any
of the RIRs in order to complete these allocations. Addresses that are
left over will be held in the Reclamation Pool until additional IP
addresses are returned, or a minimum allocation unit is achieved that
allows continued allocations from the pool.

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 this policy has been adopted by the ICANN
Board of Directors 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 report confirming
RIR eligibility subsequent to Section 4.

6. No Transfer Rights
Address space assigned from the Reclamation Pool is not subject to
transfer outside of an ICANN Board adopted globally adopted transfer
policy. The definition of Global Transfer Policy for the purpose of
this policy is a global policy that has been processed and adopted by
ICANN in compliance with the MoU [2] and attachments as agreed to in
October 2004 between ICANN and the RIRs.

7. Definitions
IANA - Internet Assigned Numbers Authority or it's successor
ICANN - Internet Corporation for Assigned Names and Numbers or it's successor
RIR - Regional Internet Registry as recognized by ICANN
MOU - Memorandum of Understanding between ICANN and the RIR's
IPV4 - Internet Protocol Version Four, the target protocol of this Global Policy
