Hello all,

The proposal is now up on the website and can be assessed at

> 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

> * 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

> 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

> 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

> 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.
