      1.  Introduction
      ----------------
      
      This is a policy proposal to recover unused historical AS numbers for
      eventual reassignment to other APNIC account holders.
      
      
      2. Definitions
      --------------
      
      Historical AS numbers:     Historical resources AS numbers that were
                                  registered under early registry policies
                                  without formal agreements. For more
                                  information, see section 2 of "Policies for
                                  historical Internet resources in the APNIC
                                  Whois Database" [1].
      
      Unused AS numbers:         Any AS number which has not appeared in the
                                  global routing tables for some specified
                                  period of time, as determined by the Routing
                                  Information Service (RIS) or other agreed
                                  means.
      
      
      3.  Summary of current problem
      ------------------------------
      
      APNIC has 115 historical AS numbers which transfered to APNIC during the
      Early Registry Transfer (ERX) project. The full list is available from:
      
           http://www.apnic.net/erx
      
      
      Currently, around 45% of the historical AS numbers registered in the
      APNIC Whois Database do not appear in the global routing tables.
      Assuming these AS numbers remain unused, these AS numbers
      could be made available for redistribution to other networks.
      
      While APNIC has the ability to reclaim unused AS numbers assigned under
      current policies [2], there is no equivalent policy for historical AS
      numbers.
      
      In 2004, to help address the decreasing size of the unallocated IPv4
      pool, the APNIC community adopted a policy to recover unused
      historical IPv4 addresses:
      
           http://www.apnic.net/policy/proposals/prop-017
      
      This proposal would allow a similar mechanism to exist for historical AS 
      numbers.
      
      
      4.  Situation in other RIRs
      ---------------------------
      
      No similar policy exists in other regions.
      
      
      5.  Details of the proposal
      ---------------------------
      
      It is proposed that APNIC recover and reassign historical AS numbers
      that have not been used for a reasonable period of time.
      
      Please see Appendix A for the administrative procedure that would be
      used to carry out this policy.
      
      
      6.  Advantages and disadvantages of the proposal
      ------------------------------------------------
      
      6.1 Advantages
      
           This proposal would release unused AS numbers back into the
           unassigned pool.
      
      
      6.2 Disadvantages
      
           This proposal would result in a minor increase in the workload
           of APNIC hostmasters.
      
      
      7.  Effect on APNIC members
      ---------------------------
      
      There is no direct impact to normal APNIC members.
      
      
      8.  Effect on NIRs
      ------------------
      
      NIRs are encouraged to help APNIC reclaim unused historical AS numbers
      within their economies.

      10. Appendix A: Administrative procedure for historical AS number
           reclamation
      -----------------------------------------------------------------
      
           1. The APNIC Secretariat will identify unused historical AS numbers
               and generate a list.
      
      
           2. The APNIC Secretariat will notify organizations responsible for
              unused historical AS numbers by all available means and contact
              the associated NIR if applicable.
      
              The APNIC Secretariat will use all available contact details from
              APNIC records. Responses will be tracked using dedicated return
              email addresses and APNIC's request tracking system.
      
      
           3. Responses to these notifications will be handled using one of
              three possible options:
      
              A. If a response is received and AS number holder agrees to
                 return the AS number:
      
                 - The AS number will be reclaimed.
      
      
              B. If a response is received and AS number holder does not agree
                 to return the AS number:
      
                 - The holder retains the AS number.
                 - All future handling of the historical AS number
                   will be guided by the "Policies for historical Internet
                   resources in the APNIC Whois Database"[1] at:
      
                   http://www.apnic.net/policy/historical-resource-polices.html
      
      
              C. If no response is received after 3 contacts in 3 months (or if
                  only error responses or bounces are received):
      
                   - The AS number will be reclaimed.
      
      
           4. All reclaimed AS numbers will be removed from public APNIC Whois
              Database and kept in the APNIC unallocated pool for 12 months
              before redistribution to other networks.
