IPv6 Readiness Measurement BoFAPNIC 43

28 February 2017

Summary of IPv6 deployment status in Japan

n Networksn Major three cellular carriers announced they

would start full IPv6 service in 2017.n One of them has started their IPv6 service.

n Many fixed-line ISPs have started their commercial IPv6 service for both enterprise and consumer users.

n Some ISPs have been migrating their existing IPv4 only users to dual stack environment.

n Contentsn IPv6 ready Government’s services are increasing.n Large contents provides do not support IPv6 yet.

n Start considering to implement.

Recent IPv4 over IPv6 implementation in Japan

n Cost of dual stack network management is so high.n Implementation of “IPv4 as a Service

(IPv4aaS)” is ongoing world-widely.n IPv4aaS: Providing IPv4 Internet access service on

IPv6 only network.n Some U.S. cellular carriers have implemented

IPv4aaS, and some U.S. contents providers consider to migrate their internal network to IPv6 only.
