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 migrate their existing IPv4 only users to dual stack environment.

n  Total IPv6 Internet users are increasing.

n  A few cellular carriers provide IPv6 connectivity.

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