      1.  Introduction
      This is a proposal to change the minimum IPv4 allocation size from /21
      to /24 and to create a new membership tier with an annual fee of
      AU$500 for members with a /24 allocation.
      2.  Summary of current problem
      If a small ISP receives the current minimum IPv4 allocation size of
      /21, the ISP falls into the Small APNIC membership tier and must pay
      an annual fee of AU$3,169 [1].
      In India, there are a lot of smaller ISPs who do not actually require
      a /21. These ISPs would be satisfied with even a /24 if it meant that
      the associated fees for the allocation were reduced. However, the
      option of an allocation of less than a /21 is not currently available,
      meaning that small ISPs must pay a minimum of AU$3,169 per year for an
      3.   Situation in other RIRs
      The minimum IPv4 allocation sizes in other RIR regions are:
      - AfriNIC:  /22
      - ARIN:     /22 for multihoming, otherwise /20
      - LACNIC:   /20
      - RIPE:     /21
      4.   Details of the proposal
      It is proposed that:
           1. The minimum IPv4 allocation size be changed from /21 to /24.
           2. A new membership tier be introduced for /24 allocations.
              This new tier will have an annual fee of AU$500.
      5.   Advantages and disadvantages of the proposal
      - Small ISPs will be able to request an allocation smaller than a /21.
      - More small ISPs will be able to afford direct allocations from
      - IP resources can be saved by reducing potential waste associated
         with giving a /21 to small ISPs that do not need that much space.
      - No disadvantage to anybody.
      6.   Effect on APNIC members
      A lot of new smaller members will join APNIC.
      7.   Effect on NIRs
      No effect.
