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.
