This is version 2 of the draft global v4 policy text that was previously
posted for comments. It has incorporated significant feedback from a variety
of participants from multiple communities.
Additional comments, public or private, are welcome. We're collecting

Global Policy for IPv4 Allocations by the IANA Post Exhaustion
This policy defines the process for the allocation of IPv4 addresses post
"Exhaustion Phase". 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
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
* Encourages the return of IPv4 address space by making this re-allocation
* Disallows transfers 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 excluding RIR's and the addresses that RIR's may return directly.
* Includes any length of fragments currently held by the IANA now or in the
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 their
inventory of IP address space, this Reclamation Pool will be declared
2. Returning Address Space to the IANA
The IANA will accept all eligible address space that is offered for return.
Eligible address space includes legacy address space and address space
returned by the RIR to which it is assigned.
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 RIR's 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
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 are 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 who
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 a globally adopted transfer policy. The definition of Global
Transfer Policy for the purpose of this policy is a policy that has been
processed in compliance with the MoU

to in October 2004 between ICANN and the RIR's.
