3. Background 16 Feb 2009: prop-062 (Use of final /8) was finalized 6 Mar 2009: ICANN board ratified the ‘Global Policy for the Allocation of the Remaining IPv4 Address Space’, which directs IANA to split its last five /8 blocks evenly to each of the RIRs 26 Aug 2010: APNIC Secretariat presented the Three-Stage final /8 implementation plan 3

4. APNIC’s 3 Stages of IPv4 Exhaustion Stage 1 IPv4 available at IANA for normal distribution Stage 2 Began when IANA distributed the last five blocks to the RIRs Stage 3 Began when APNIC reached the last /8 of IPv4 in its free pool 4

6. Stage 1 – 2 transition 6

7. Challenge To predict the next request to IANA that will trigger IANA’s last five /8 blocks condition To prepare coordinated public communications between ICANN/IANA and all the RIRs 7

8. Stage 1 – 2 transition 19 Jan 2011: APNIC qualifies for subsequent IPv4 allocations from IANA, and submitted a request 20 Jan – 2 Feb 2011: Public communication coordination with ICANN/IANA, RIRs and NIRs 31 Jan 2011: APNIC received two IPv4 /8 blocks from IANA that triggered the last five /8 IANA allocations to the RIRs 3 Feb 2011: IANA IPv4 depletion is publicly announced 8

9. NRO Press Release 9 Montevideo, 3 February 2011 – The Number Resource Organization (NRO) announced today that the free pool of available IPv4 addresses is now fully depleted. On Monday, January 31, the Internet Assigned Numbers Authority (IANA) allocated two blocks of IPv4 address space to APNIC, the Regional Internet Registry (RIR) for the Asia Pacific region, which triggered a global policy to allocate the remaining IANA pool equally between the five RIRs. Today IANA allocated those blocks. This means that there are no longer any IPv4 addresses available for allocation from the IANA to the five RIRs. More...

14. Stage 2 Concluded 15 April 2011: The APNIC Secretariat announced it reached its final /8 of available IPv4 space 328 requests approved 181 requests missed their allocations Most of them accepted a /22 allocation 6 complaints received – all resolved now 14

15. Life in Stage 3 From 15 April to 27 August 2011 IPv4 delegation: 583/30 economies (6/day) IPv6 delegation: 242/26 economies (2.5/day) New members: 181/17 economies (~2/day) New policies implemented on 9 May 2011 to reduce delegation size to a /24 with no renumbering requirement 15

16. Life in Stage 3 What if a Member needs more IPv4 space than its last /22 delegation? The IPv4 Transfer Policy is available to allow transfers of unused address space to the Member Use the network operator group or apnic-talk mailing list to find transfer sources Inter-regional transfers can be received under APNIC policy, where other regions permit this Additional addresses may be distributed from IANA if returns are made to IANA and the global policy allows it 16

17. Conclusion The APNIC community worked well together in managing IPv4 exhaustion by preparing a set of policies that gave the APNIC Secretariat guidance to manage the IPv4 exhaustion The APNIC Secretariat successfully implemented the IPv4 last /8 policy through careful planning and execution of processes and procedures, and by keeping the community well informed throughout the stages 17
