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
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

APNIC’s 3 Stages of IPv4 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
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

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.

Stage 2 – 3 transition

mechanism• To apply the same mechanism to APNIC direct

Last /8reached
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
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
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
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
