Overview Background APNIC’s 3 Stages of IPv 4 Exhaustion Stage 1– 2 transition Stage 2 – 3 transition Life in Stage 3 Conclusion References 2

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 IPv 4 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

APNIC’s 3 Stages of IPv 4 Exhaustion • Stage 1 • IPv 4 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 IPv 4 in its free pool 4

APNIC’s 3 Stages of IPv 4 Exhaustion 5

Stage 1 – 2 transition 6

Stage 1 – 2 transition • 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

Stage 1 – 2 transition • 19 Jan 2011: APNIC qualifies for subsequent IPv 4 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 IPv 4 /8 blocks from IANA that triggered the last five /8 IANA allocations to the RIRs • 3 Feb 2011: IANA IPv 4 depletion is publicly announced 8

NRO Press Release Montevideo, 3 February 2011 – The Number Resource Organization (NRO) announced today that the free pool of available IPv 4 addresses is now fully depleted. On Monday, January 31, the Internet Assigned Numbers Authority (IANA) allocated two blocks of IPv 4 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 IPv 4 addresses available for allocation from the IANA to the five RIRs. More. . . 9

Stage 2 – 3 transition 10

Stage 2 – 3 transition • Challenge • To set up a strict first-come-first-served mechanism • To apply the same mechanism to APNIC direct Members and NIR members 11

Stage 2 Concluded • 15 April 2011: The APNIC Secretariat announced it reached its final /8 of available IPv 4 space • 328 requests approved • 181 requests missed their allocations • Most of them accepted a /22 allocation • 6 complaints received – all resolved now 14

Life in Stage 3 • From 15 April to 27 August 2011 • IPv 4 delegation: 583/30 economies (6/day) • IPv 6 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

Life in Stage 3 • What if a Member needs more IPv 4 space than its last /22 delegation? • The IPv 4 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

Conclusion • The APNIC community worked well together in managing IPv 4 exhaustion by preparing a set of policies that gave the APNIC Secretariat guidance to manage the IPv 4 exhaustion • The APNIC Secretariat successfully implemented the IPv 4 last /8 policy through careful planning and execution of processes and procedures, and by keeping the community well informed throughout the stages 17
