        1. Problem statement
        --------------------

        There are a lot of transfers of IPv4 address blocks from 103/8
        happening, both within the APNIC region and among RIRs.

        Then number of transfer from 103/8 block are about 200, which is
        about 12% of the total number of transfers. This looks so high
        since APNIC manages about 40/8.

        And based on the information provided by APNIC secretariat, number
        of transfers from the 103/8 block are increasing year by year.

        Updated by APNIC Secretariat on 27 January 2017:

        1) M&A transfers containing 103/8 space

        +------+-----------+-----------+-
        |      |   Total   | Number of |
        | Year | Transfers |   /24s    |
        +------+-----------+-----------+-
        | 2011 |         3 |         12 |
        | 2012 |        10 |         46 |
        | 2013 |        18 |         66 |
        | 2014 |       126 |        498 |
        | 2015 |       147 |        573 |
        | 2016 |        63 |        239 |
        +------+-----------+------------+-

        2) Market transfers containing 103/8 space

        +------+-----------+-----------+
        |      |   Total   | Number of |
        | Year | Transfers |   /24s    |
        +------+-----------+-----------+
        | 2011 |         2 |         2 |
        | 2012 |        21 |        68 |
        | 2013 |        16 |        61 |
        | 2014 |        25 |        95 |
        | 2015 |        67 |       266 |
        | 2016 |       103 |       394 |
        +------+-----------+-----------+

        And also, transfers from the 103/8 block include:
          - Take place within 1 year of distribution, or
          - Multiple blocks to a single organization in case of beyond 1 year.

        Further, there is a case where a single organization have received 12
        blocks transfers from 103 range.

        see:  https://www.apnic.net/transfer-resources/transfer-logs

        From these figures, it is quite likely that substantial number of 103/8
        blocks are being used for transfer purpose.

        This conflicts with the concept of distribution of 103/8 block
        (prop-062), which is intended to accommodate minimum IPv4 address blocks
        for new comers.

        2. Objective of policy change
        -----------------------------

        When stated problem is solved, distribution from 103/8 block will be
        consistent with its original purpose, for distribution for new entrants
        to the industry. Without the policy change, substantial portion of 103/8
        blocks will be consumed for transfer purpose.


        3. Situation in other regions
        -----------------------------

        None.


        4. Proposed policy solution
        ---------------------------

        Prohibit transfer IPv4 addresses under /8 address block (103/8) which
        have not passed two years after its allocation/assignment.
        If the address block allocated to a LIR in two years is not needed any
        more, it must return to APNIC to allocate to another organization
        using final /8 policy.

        In the case of transfers due to M&A, merged organization can have
        up to /22 IPv4 address in the 103/8 block in principle. If there
        are technical reasons such as all address is used in separate networks
        and announced from multiple ASes, merged organization can keep them.
        Otherwise, the 103/8 IPv4 address more than /22 must return to APNIC
        to allocate to another organization using final /8 policy.


        5. Advantages / Disadvantages
        -----------------------------

        Advantages:
          - It makes 103/8 blocks available according to the original purpose,
            as distribution for new entrants (rather than being consumed for
            transfer purpose)

          - IPv4 addresses under final /8 are not transferred to outside APNIC.

          - By prohibiting transfer them, it is possible to keep one /22 for
            each LIRs state, which is fair for all LIRs.

        Disadvantages:

        None.


        6. Impact on resource holders
        ------------------------------

          - LIRs cannot transfer address blocks under 103/8. No big impact while
            they use it.

          - Organizations which needs to receive transferred IPv4 can continue
            to do so, outside 103/8 blocks (which should be made available for
            new entrants)
