1. Being successful?Update from Japan’s Internet IPv6: How ready is Asia for this critical resource? APrIGF, June 16 2011 MAEMURA Akinori （前村 昌紀） JPNIC / Task Force on IPv4 Address Exhaustion, Japan

2. Two recent developments MAEMURA Akinori, June 16, 2011

3. KDDI announced IPv6 provision • Monday April 18 – just after APNIC’s runout • effective immediately • on its FTTH solution “au Hikari（光）” • No additional fee, no customer action needed http://www.kddi.com/corporate/news_release/2011/0418a/ MAEMURA Akinori, June 16, 2011

4. NTT’s FLETS Hikari starts IPv6 Internet access • NTT’S FLETS connects ISP and end-user residences • FLETS Hikari（光） Next == NTT’s NGN offer • After years consideration • Multiple ISPs havealready announcethe adoption MAEMURA Akinori, June 16, 2011 http://www.ntt-east.co.jp/release/1105/110526c_2.html

5. Observation from Operators being successful MAEMURA Akinori, June 16, 2011

6. IPv6, standardized in 1995, • And assumed to be deployed gradually replacing IPv4by the exhaustion of it • But it never happened until now Actual Assumption MAEMURA Akinori, June 16, 2011 http://www.potaroo.net/ispcol/2008-10/v4depletion.html

7. Why not? • No compatibility with IPv4 • No direct merit for users • Significant cost MAEMURA Akinori, June 16, 2011

8. Which is reasonable way to go? Exhaustion of IPv4 Address Growth of the Internet IPv4 Internet IPv6 Internet Internet with full of services and eyeballs Internet with few services and few eyeballs Network Externalitysays IPv4 At least until the exaustion MAEMURA Akinori, June 16, 2011 Growth of the Internet

9. Dilemma of Operators and solution for it • Definitely needs IPv6 for Future Internet • to accommodate more services and eyeballs • Significant Cost for no direct merit for customers • Need a miracle? • Need Government fund? • A solution: long, steady, low-key and patient endeavors make it happen MAEMURA Akinori, June 16, 2011

10. Operators being successful has been taking long, low-key and patient efforts • Time is money – Plan and action over years will benefit in many aspects: • Many small investments are easier to be justified than few big investments • IPv6 enabled equipment to renew on depreciation • Firmware upgrade when IPv6 enabled version got available reasonably • Play with lab network and learn about IPv6 to gain the expertise: literacy reduces the cost MAEMURA Akinori, June 16, 2011

11. There has been no miracle… • Task Force on IPv4 Address Exhaustion, Japan • three years since 2008 • actions to multi-stakeholders • Information – action plan template, training, reference network design, status update • NTT FLETS is at last being ready • Most ISPs can use it for their IPv6 access from residences • Operators has been taking patient efforts • Bottom up, low-key, long and steady • Gradually prepare for IPv6, in order to save the customers from the crisis MAEMURA Akinori, June 16, 2011
