APNIC Last /8 Policy Implementation Report

This report provides an overview of APNIC's implementation of the Last /8 Policy for IPv4 exhaustion, including the transition from Stage 1 to Stage 2, and life in Stage 3. It also discusses the challenges faced and the successful execution of the policy.

  1. APNIC Last /8 Policy Implementation Report SanjayaServices Area Director

  2. Overview • Background • APNIC’s 3 Stages of IPv4 Exhaustion • Stage 1– 2 transition • Stage 2 – 3transition • Life inStage 3 • Conclusion • References

  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

  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

  5. APNIC’s 3 Stages ofIPv4 Exhaustion

  6. Stage 1 – 2 transition

  7. Stage 1 – 2 transition • Challenge • To predict the next request to IANA that will triggerIANA’slast five /8 blocks condition • To prepare coordinated public communications between ICANN/IANA and all the RIRs

  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

  9. NRO Press Release 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...

  10. Stage 2 – 3 transition

  11. 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

  12. IPv4 Delegation Practice in Stage 2 Requestor Delegation approval 5 business days • Clarification questions • Declined request • Last /8 policy applied Time • Request more info Yes Approved? Evaluation Queue No Need more info? • Apply last /8 policy • Decline request Yes No No Approved queue • Delegate resource Yes More than /8 left?

  13. Stage 2 Queues 5 days? 5 days? Y Y Delegate and email member Last /8 reached Enough Info? Y N Requestor Response *) Not real data, for illustration only

  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

  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

  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

  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

  18. References • Global Policy for the Allocation of the Remaining IPv4 Address Space (IANA) • Policies for IPv4 address space management in the Asia Pacific region (apnic-124-v001) • Prop-062: Use of final /8 • Prop-088: Distribution of IPv4 addresses once the final /8 period starts • Prop-093: Reducing the minimum delegation size for the final /8 policy • Prop-094: Removing renumbering requirement from final /8 policy • Prop-050: IPv4 address transfers • Prop-095: Inter-RIR IPv4 address transfer proposal
