  1. Transforming the Internet:from IPv4 to IPv6 HK IPv6 Conference Hong Kong 23 November 2009 By Miwa Fujii IPv6 Program Manager, APNIC

  2. Overview • Recap: IP addresses management • What is currently happening with the Internet? • IPv4 address free pool exhaustion • IPv6 deployment status • Readiness of resource management policies • How is the APNIC community responding? • IPv6 readiness survey • How is the technical community responding? • Are you ready for these changes? • What do you need to do?

  3. How are IP Addresses Managed? • Regional Internet address Registries • Open membership-based industry bodies • Non-profit, neutral, and independent • Allocation, registration and other services • APNIC: training, infrastructure, cooperation • First established in early 1990s • Voluntarily by consensus of community • To ensure responsible address management, according to technical and administrative needs • To support Internet development • In the “Internet tradition” • Consensus-based, open, and transparent

  4. End user Where do IP addresses come from? Standards Allocation * Allocation Regional Internet Registries (RIR) distribute IPv4, IPv6, and AS numbers to the Internet community RIRs maintain accurate registration of Internet resource usage for the community Assignment * In some cases via an NIR, such as CNNIC, JPNIC etc.

  5. Regional Internet Registries The Internet community established the RIRs to providefair and consistent resource distribution and accurateresource registration throughout the world.

  6. The policy development process Need OPEN Anyone can participate Evaluate Discuss ‘BOTTOM UP’ TRANSPARENT Implement Consensus Internet community proposes and approves policy All decisions & policies are documented & available

  7. Current policy discussions • We are experiencing an important turning point in the history of the Internet • IPv4 allocation policies are changing • Prop-50 IPv4 address transfers • Deregulated transfers of IPv4 blocks • Allow address transfer between APNIC account holders • The minimum transfer size: /24 • APNIC to maintain a public log of all transfers • APNIC to maintain accurate registrations • It has been under discussion since Sept 2007 • Reached consensus at APNIC28 • Endorsed by EC in Nov 2009

  8. Current policy discussions • Prop-073: Simplifying allocation/assignment of IPv6 to APNIC members with existing IPv4 addresses • This proposal directs the APNIC Secretariat to automatically assess and provide IPv6 resources to APNIC members that currently hold IPv4 resources but who do not hold IPv6 resources in the APNIC registry • Reached consensus at APNIC28 • Endorsed by the APNIC EC in November 2009 • Participate policy discussion! • http://www.apnic.net/community/participate/join-discussions • Learn about other recent policy changes • http://www.apnic.net/community/policy/proposals • Join discussions • http://www.apnic.net/community/participate/join-discussions

  21. APNIC IPv6 Readiness Survey 2009 • Deployed or ready for immediate deployment? • Formal plan for future deployment? • Budgeted for future deployment?

  22. and more devices need to connect too! Billions of them

  23. Strategies available for ISPs • Do nothing • Wait and see what competitors do • Business not growing, so don’t care • Extend life of IPv4 • Push customers to NAT • Buy IPv4 address space on the marketplace • Deploy IPv6 • Dual stack infrastructure • IPv6 and NATed IPv4 for customers • Or various other combinations of IPv6, IPv4 and NAT Slide#22, “The Next Three Years (IPv4 rouout and the motivation for IPv6, presented by Philip Smith, Cisco at MENOG5, Beirut, Oct 2009

  24. Available options for ISPs Renumbering from own networks which does not require global IP Squeese out IPv4 addresses from your networks Short term Solution: Limited effect Obtain additional IPv4 addresses Externally obtain IPv4 addresses IP address transfer IPv4 address exhaustion Mid term Solution: IETF discussion Providing IPv4 connectivity services Sharing IPv4 address among customers Not to obtain additional IPv4 addresses Providing no IPv4 connectivity services Long term Solution: IPv4 compatibility issue Run your business with IPv6 only Slide#7, “Consideration on network models during the period of IPv4 address exhaustion, by Akira Nakagawa, KDDI, Nov 2009

  25. Technical community’s responses • Prolonging IPv4 to help with IPv6 • Large variety of proposals to “make IPv4 last longer” to help with IPv6 deployment • All involve Large Scale NAT (LSN) • NAT444/SP NAT • NAT to customer, NATed core • Dual Stack Lite • Private IPv4 to IPv6 to Public IPv4 • Activity of IETF Softwire Working Group • NAT64 &IVI • Translation between IPv6 and IPv4 • Activity of IETF Behave Working Group Slide#23, “The Next Three Years (IPv4 rouout and the motivation for IPv6, presented by Philip Smith at MENOG5, Beirut, Oct 2009

  26. Dual Stack Network • The original transition scenario, but dependent on: • IPv6 being available all the way to the customer • Sufficient IPv4 address space for the customer Slide#24, “The Next Three Years (IPv4 rouout and the motivation for IPv6, presented by Philip Smith, Cisco at MENOG5, Beirut, Oct 2009

  27. NAT444/SP NAT • Consumer uses private IPv4 and native IPv6 • SP uses private IPv4 and native IPv6 for backbone Slide#25, “The Next Three Years (IPv4 rouout and the motivation for IPv6, presented by Philip Smith, Cisco at MENOG5, Beirut, Oct 2009

  28. Dual Stack Lite • SP has IPv6 only infrastructure • For consumer, IPv4 tunnel to SP NAT, IPv6 native Slide#26, “The Next Three Years (IPv4 rouout and the motivation for IPv6, presented by Philip Smith, Cisco at MENOG5, Beirut, Oct 2009

  29. NAT64 • Consumer uses only IPv6 plus Protocol Translation to reach IPv4 • Service Provider uses only IPv6 Slide#27, “The Next Three Years (IPv4 rouout and the motivation for IPv6, presented by Philip Smith, Cisco at MENOG5, Beirut, Oct 2009

  30. The future… • The Internet has already shown its ability to evolve • Those who are building the Internet need to be aware of IPv4 consumption and IPv6 transition • ISPs, content providers, vendors, applications • Planning should start now, in detail, for the day when there is not enough IPv4 address space • Implementation plan, budget, and allocation of resources • A smooth transition is still possible

  31. Transition planning for content providers: Multihoming via IPv6 • Obtain IPv6 address assignment • Find an ISP that can provide you IPv6 connectivity • Contract to secure IPv6 connectivity • Use tunnels if necessary • Find Internet exchange points that support IPv6 • Peer with other IPv6 networks as much as you can

  32. Transition planning for network operators: Deploy IPv6 by 2010 • Your customers - for example, content providers, enterprises etc - will eventually demand IPv6 connectivity • Be ready for them! • Plan for deployment • APNIC suggests that network operators and service providers be prepared to support customers and services using IPv6 by 2010 • Build IPv6 into regular product upgrade cycles • Contact your vendors now!

  33. Transition planning governments: Support the industry • Industry, regulators, and public policy makers • Develop a coherent strategy to sustain the transitional framework between IPv4 and IPv6 • Deploy IPv6 in government infrastructures, and require it of your suppliers • Encourage the continuing contribution of various stakeholders in mutually supportive roles • Keep up-to-date with topics of IPv4 address exhaustion and IPv6 transition

  34. IPv6 deployment opportunities • What benefits can you create by deploying IPv6 in your region? • A new industry without much legacy • Effective use of the Internet for socio-economic development? • Point-to-point connectivity in remote learning environments? • Effective use of multicasting to conserve bandwidth? • Stable, continuous Internet for: • Disaster risk management and risk reduction? • Early warning and response to disaster risks? • Effective use of IPv6’s new features? • Transportable communication system for effective disaster and emergency management? • Energy efficient networks? • Deploy new technologies with less power consumption? • Positive impact to the environment?

  35. Recent IPv6 implementation caseQ2, 2009 • Sify.com India enabled their services with IPv6 • Internet access to enterprise customers • MPLS-based IP-VPN services • Orange Business Services deployed IPv6 in its MPLS IP VPN backbone • Available in 35 countries in Q2 2009 • Gradually extended to more than 100 • FX Networks in NZ • High performance national Internet backbone is natively running IPv6 in parallel with IPv4 and is available for customers to use • To sustain their business with Asian business partners http://sev.prnewswire.com/computer-networks/20090528/3907349en_iCrossing28052009-1.html http://www.orange.com/en_EN/press/press_releases/att00012170/print.jsp http://www.geekzone.co.nz/content.asp?contentid=8251

  36. IPv6 services deployment plan • Internode • IPv6 Broadband Trial Services • http://ipv6.internode.on.net/access/adsl/ • Providing a testing environment for existing ADSL users • Capacity building exercise for Internode engineers • Comcast • Making IPv6 transit services available to its wholesale customers • Then making IPv6 available to Comcast's business and residential broadband customers • Broadband IPv6 technical trials later this year and into 2010 • AT&T • Plans to launch commercial IPv6-based service offerings in 2009 • The rationale and strategies for AT&T and enterprise customers to plan for and initiate transition towards IPv6 deployments • http://www.business.att.com/content/whitepaper/WP-IPv6_18359_v1_5-11-09.pdf http://www.internetnews.com/infra/article.phpr/3825696/Comcast+Embraces+IPv6.htm June 2009 http://www.business.att.com/content/whitepaper/WP-IPv6_18359_v1_5-11-09.pdf Nov 2009
