Official Announcement of “Third Progress Report” from the Study Group on Advanced Use of Internet with IPv6

1.Background

  The stock of IPv4 (Note 1) addresses owned by APNIC that distributes IP addresses to the Asia Pacific area and by JPNIC that manages IP addresses in Japan depleted in April, 2011. In response to a situation where the full-fledged provision of IPv6 (Note 2) Internet connection services by Internet service providers has started, a “Third Report” was compiled at the Study Group in December 2011.
  The Study Group has verified the state of progress of response to various issues pointed out in the third report and examined future priority issues and countermeasures against them from a viewpoint of further accelerating the expansion of use of IPv6 internet connection services since May 2012, and they have now been compiled as the “Third Progress Report.”

  (Note 1) IPv4 (Internet Protocol Version 4): A communication system used as a major fundamental technology of the current Internet. Numbers to identify computers connected to the network are called as IP addresses and the number of IPv4 addresses is approximately 43 billion.
  (Note 2) IPv6 (Internet Protocol Version 6): This is a successor specification of IPv4 characterized by the almost unlimited number of IP addresses that are available for assignation compared to IPv4 (approximately 3.4x1038 (340 trillion x 1 trillion x 1 trillion) addresses), addition of security functions, simplified address setting, etc.
