Second Progress Report Released by Study Group on Advanced Use of Internet with IPv6

The Ministry of Internal Affairs and Communications (MIC) has been holding the Study Group on Advanced Use of Internet with IPv6 (chaired by Tadao Saito, Professor Emeritus at the University of Tokyo) since February 2009 to consider promotional measures for the smooth introduction of IPv6.
Recently, the Study Group finished the second progress report, and the MIC announces it.

1. Outline

The Asia Pacific Network Information Centre (APNIC) (the Regional Internet Registry for the Asia Pacific region) and the Japan Network Information Center (JPNIC) (the National Internet Registry in Japan) ran out of IPv4 (see note 1) addresses in stock in April 2011. Then the provision of IPv6 (see note 2) Internet connection service by Internet service providers (ISPs) started in full swing. With consideration of these circumstances, the Study Group announced promotional measures for the smooth introduction of IPv6 in its third interim report in December 2011 and released a progress report, including the verification results of the progress of the contents of the third interim report, in July 2012.
From the viewpoint of further accelerating an expansion of the use of IPv6 Internet connection service, the Study Group started verifying the progress of solutions this April to various issues pointed out in the third interim report and progress report while considering key issues for the future along with solution measures to the key issues. Recently, the Study Group finished the second progress report.

Approximately 4.3 billion IPv4 addresses are available.
