Studies and Activities
before the Task ForceReports on IPv4 Address
Exhaustion• JPNIC (Dec 2007) and MIC (June 2008) as separate
studies– Japanese• JPNIC - http://www.nic.ad.jp/ja/ip/ipv4pool/ipv4exh-report-071207.pdf• MIC - http://www.soumu.go.jp/s-news/2008/pdf/080617_2_bt1.pdf– English• JPNIC - http://www.nic.ad.jp/en/research/IPv4exhaustion_transpub.pdf• MIC(full paper) http://www.soumu.go.jp/joho_tsusin/eng/pdf/080617_1.pdf• MIC(summary slides) http://www.soumu.go.jp/joho_tsusin/eng/pdf/080617_2.pdf

3Reports on IPv4 Address
Exhaustion• Both reports reached a similar conclusion as theresults of analyses– Analysis of situation surrounding IPv4 exhaustion– Issues listed, possible solutions and issues foreach solution– Concluded that IPv6 is the only effective long-termsolution after IPv4 address exhaustion• MIC report makes further analysis on action plan
broken down by categories of stakeholders
4

Activities by other bodies•IAjapan（Internet Association Japan）– Consider formations for collaboration with other bodies its Commitee•

IPv6 Promotion Council– Listing issues in IPv4/IPv6 Coexisting environment in its WG•

JAIPA（Japan Internet Provider Association）– Proposing & negotiating with NTT to support IPv6 in its FLETS service(which provides connection lines infra for ISPs)•JANOG– Topics handling IPv4 exhaustion/IPv6 transfer discussed in every
meeting since JANOG18 (July 2006)•DISTIX（Distributed IX Project)– Working on technical issues in DNS/Translators in its WG•JPNIC– Set up a website specialized to publish information related to IPv4exhaustion

9The major problems• Although there is higher awareness by major
operators/LIRs on personal level…

– IPv6 Deployment requires additional cost in short term anddifficult to justify– Little real-life deployment experience in IPv6 and nosufficient expertise by vendors– Technology for interworking between IPv4 and IPv6 isinevitable during the transition phase, but no technology at
production level so far– Service providers and venders are watching and waiting tosee each others to take action• A collaborated activity is necessary as a break throughfrom “watching to see what the others will do” state10Task Force on IPv4 Address
Exhaustion, Japan

Synchronized action toward
exhaustion• Set up a TF to make co-ordinated actions
among all stakeholder groups• Task Force on IPv4 Address Exhaustion,
Japan – IPv4アドレス枯渇対応タスクフォース– Various associations
from Telco and Internetindustries– MIC participates
12

Charter – the taskforce• Formulating a taskforce to synchronize theactivities by various associations• to overcome the crisis of the IPv4 address
exhaustion in a coordinated manner• In four aspects of– Solution of the issues – technique, operation andmanagement– Enlightenment and publicity– Education– Progress management
