      I invite you all to review the proposal below and send comments to the
      mailing list before APNIC 24.

      1.  Introduction
      ----------------
      
      This proposal is to have a global policy for the Regional Internet
      Registries (RIRs) to receive blocks of Autonomous System Numbers (ASNs)
      from the Internet Assigned Numbers Authority (IANA).
      
      
      2.  Summary of current problem
      ------------------------------
      There are global policies governing the allocation of IPv4 and IPv6
      blocks from the IANA to RIRs. At this point there is no specific policy
      regarding the allocation of Autonomous System Numbers from the IANA to
      the RIRs. This proposal will create a policy to fill this gap.
      
      
      3.   Situation in other RIRs
      ----------------------------
      
      This proposal was adopted by the LACNIC region and is in its concluding
      phase in the RIPE region. It will soon be submitted to the AfriNIC
      and ARIN communities for discussion.
      
      
      4.   Details of the proposal
      ----------------------------
      
      Abstract
      
      This document describes the policy governing the allocation of
      Autonomous System Numbers (ASNs) from the IANA to the Regional Internet
      Registries (RIRs).
      
      This policy document does not stipulate performance requirements in the
      provision of services by the IANA to an RIR. Such requirements will be
      specified by appropriate agreements between ICANN and the Number
      Resource Organization (NRO).
      
      1. Allocation principles
      
          IANA allocates ASNs to RIRs in blocks of 1024 ASNs. In this document
          the term "ASN block" refers to a set of 1024 ASNs. Until 31 December
          2009, allocations of 2-byte only and 4-byte only ASN blocks will be
          made separately and independent of each other.[1] This means
      until 31
          December 2009, RIRs can receive two separate ASN blocks, one for
          2-byte only ASNs and one for 4-byte only ASNs from the IANA under
          this policy. After this date, IANA and the RIRs will cease to make
          any distinction between 2-byte only and 4-byte only ASNs, and will
          operate ASN allocations from an undifferentiated 4-byte ASN
          allocation pool.
      
      
      2. Initial allocations
      
          Each new RIR will be allocated a new ASN block.
      
      
      3. Additional allocations
      
          An RIR is eligible to receive (an) additional ASN block(s) from the
          IANA if one of the following conditions is met:
      
          1. The RIR has assigned 80% of the previously received ASN block
             or
      
          2. The number of free ASNs currently held by the RIR is less than
      two
             months need. This projection is based on the monthly average
             number of ASNs assigned by the RIR over the previous six months.
      
          An RIR will be allocated as many ASN blocks as are needed to support
          their registration needs for the next 12 months, based on their
          average assignment rate over the previous six months, unless the RIR
          specifically requests fewer blocks than that for which it qualifies.
      
      
      4. Announcement of IANA allocations
      
          The IANA, the NRO and the RIRs will make announcements and update
          their respective websites/databases when an allocation is made by
          the IANA to an RIR. ICANN and the NRO will establish administrative
          procedures to manage this process.

      5.   Advantages and disadvantages of the proposal
      -------------------------------------------------
      
      Advantages:
      
      The criteria being proposed has already been the practice between IANA
      and RIRs so far and it has been proven to work. It is designed to allow
      RIRs to request ASN blocks from the IANA in a timely fashion and
      maintain enough ASNs in holding to ensure that their registration
      services can be sustained.
      
      It is also proposed that the RIRs be allocated as many ASN blocks as
      are needed to support their registration needs for the next 12 months.
      This will generally mean that each RIR will only need to make one ASN
      request from the IANA each year, thus lowering operational overhead for
      the RIRs.
      
      Disadvantages:
      
      None.
      
      
      6.   Effect on APNIC members
      ----------------------------
      
      None.
      
      
      7.   Effect on NIRs
      -------------------
      
      None.
