      Version:   1
      
      Date:      23 July 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. 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.
      
      
      5.5 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.
