APNIC Depletion of the IPv4 free address pool – IPv6 deployment The day after!!

1. APNICDepletion of the IPv4 free address pool – IPv6 deploymentThe day after!! 8 August 2008 Queenstown, New Zealand In conjunction with APAN Cecil Goldstein, Training Manager

5. Let us imagine that today is the day after!!! 22 December 2011 And...you need IP address space What happens?? What will the Internet look like ? What will you do? 192.168.1.1

6. Well, that will depend on what happens between now and22 Dec 2011

7. So let us consider then where we are NOW and how we may move to THEN…….

8. end user IP Addresses – what makes the internetThe Internet IPv4 \IPv6 Allocation * Allocation Assignment * In some cases via an NIR such as KRNIC

9. The address infrastructure today 2004: Number Resource Organization

10. What is APNIC? • Regional Internet Registry (RIR) for the Asia Pacific region • Responsible for distributing Internet resources throughout the AP region • Industry self-regulatory body • Consensus-based, open, and transparent decision-making and policy development • Meetings and mailing lists • Open to anyone • http://www.apnic.net/meetings/23/index.html • http://www.apnic.net/community/lists/index.html

11. RIR policy development process OPEN Need Anyone can participate Evaluate Discuss ‘BOTTOM UP’ TRANSPARENT Consensus Implement Internet community proposes and approves policy All decisions and policies documented and freely available to anyone

12. Global policy coordination AfriNIC RIPE NCC ICANN ASO NRO APNIC LACNIC ARIN • The main function of ASO: • ASO receives global policies and policy process details from the NRO • ASO forwards global policies and policy process details to ICANN board

13. APNIC address policy

14. Policy proposals for APNIC 26 [prop-050] IPv4 address transfers [prop-055] Global policy for the allocation of the remaining IPv4 address space [prop-062] Use of final /8 [prop-063] Reducing timeframe of IPv4 allocations from twelve to six months [prop-066] Ensuring efficient use of historical IPv4 resources

15. The growth of the Internet and IPv4 unallocated address space exhaustion

16. IPv4 Address Pool – June 2005 25% Other Central Registry available APNIC RIPE NCC LACNIC AfriNIC ARIN source: http://potaroo.net

17. IPv4 IANA address pool – March 2008 16% Other Central Registry available APNIC RIPE NCC LACNIC AfriNIC ARIN source: http://potaroo.net

18. Projected lifetime of remaining IPv4 addresses RIRs pool depletion: 2nd half of 2011 IANA pool depletition: 1st Half of 2011 Current free pool41 x /8 18

20. IPv4 address consumption prediction • Assumptions • Tomorrow is a lot like today • Trends visible in the recent past continue into the future • This model assumes that there will be: • no panic • no change in policies • no change in the underlying demand dynamics • no rationing • no withholding or hoarding! • No really! Ref: IPv4 unallocated address space exhaustion by Geoff Huston, Sept 2007

21. So what will happen after the exhaustion? • The Internet will not stop but its growth will be impacted • Who will be impacted? • ISPs • Sustaining their business models will become more difficult unless you have huge IPv4 address blocks • End users • Cost of access to the Internet will increase

22. Some possible scenarios • What will happen after the IPv4 unallocated address space exhaustion? • Persist in IPv4 networks using more NATs • Address markets emerging for IPv4 • Routing fragmentation • IPv6 deployment/ transition Ref: IPv4 unallocated address space exhaustion by Geoff Huston, Sept 2007

23. Address market ?

24. IPv6 deployment Issues and concerns

25. IPv6 current deployment status • Not many cases of production networks • Not many business cases • Quite a few research and experimental networks • Some statistics to review

26. IPv4 vs IPv6 250,000 27,000 IPv4 IPv4 ASN 1,000 850 IPv6 IPv6 ASN

27. APNIC IPv6 delegations by year As of this date 27

28. Issues • Obviously not many production networks deployed • Gap in understanding between front line network engineers and decision makers • CEOs and CIOs do not seem interested or aware enough to make investments not making tangible profit • Commercial value

29. Where are we heading? We should look to preserve the functionality and integrity of the Internet as a service platform Functionality of applications Viability of routing Capability to sustain continued growth Integrity of the network infrastructure https://www.ripe.net/ripe/meetings/ripe-55/presentations/huston-ipv4.pdf

30. But this is not all….. • We are running into exhaustion of the 16-bit AS Number pool • Estimated exhaustion time: 1200 UTC 1 November 2010 • See http://www.potaroo.net/tools/asns

31. RIRs and 32-bit AS Numbers • From 1 January 2007 the RIRs are allocating 32-bit AS numbers (upon specific request) • From 1 January 2009 the RIRs will be allocating 32-bit AS numbers by default (leaving some 16-bit AS numbers available upon specific request)

32. Conclusion • Plan • Compare • Prepare • Test • Deploy IPv6 is not a new product to sell…..it is a means to sustainability
