2. Summary of IPv6 deployment status in Japan
n Networks
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 A few cellular carriers provide IPv6 connectivity.
n Major three cellular carriers announced they will start
full IPv6 service in 2017.
n Contents
n IPv6 ready Government’s services are increasing.
n Large contents provides do not support IPv6 yet.
