Network operators

IPv4 exhaustion for network operators


  • It will take APNIC a long time to completely run out of IPv4, because of the small size of allocations from the final IPv4 /8 block
  • Networks and businesses that connect to the Internet after APNIC reaches the final /8 will be eligible for a small slice of IPv4 addresses to bridge the IPv4 and IPv6 Internets for a long time to come

IPv4 delegations during Stages 1 and 2

  • Address policy remains the same until APNIC reaches the final /8
    • Criteria for justifying IPv4 addresses will not change
    • There is no maximum size delegation you can receive from APNIC
    • In Stage 2, request processing will be serialized with a standard response time of exactly five (5) business days
  • Transfers of IPv4 between APNIC members are possible, provided the recipient can justify a need for the addresses.

IPv4 delegations during Stage 3

  • As of Friday, 15 April 2011, all new and existing Members are able to access up to a maximum of /22 from the 103/8 pool and as of 27 May 2014 new and existing Members are also able to access up to a maximum of /22 from the non-103/8 pool.
  • IPv4 address transfers between APNIC Members is possible during Stage 3, with no limitations on the recipient.

Networks and organizations should begin the IPv6 deployment process now, to avoid issues with running out of IPv4 space.
