Press Release: 2008

The M-Root DNS server has its IPv6 address registered in the root zone, making DNS queries in IPv6 possible, and further accelerating transition to IPv6.
The WIDE Project (Representative: Jun Murai, Vice President, Keio University and Prof., Faculty of Environmental Information, Keio University) and Japan Registry Services Co., Ltd. (JPRS; Chiyoda-ku Tokyo; President: Koki Higashida) announced that the IPv6 address of M-Root DNS server, a jointly operated Root DNS server under responsibility of WIDE Project, has been registered with the Root zone by IANA. This registration enables DNS queries in IPv6 to Root DNS servers, and it is expected that it triggers the deployment of the IPv6.
The M-Root DNS server is one of the thirteen root servers currently operating in the world. The WIDE Project first started its operation in August 1997 as the only root server in the Asia-Pacific region. With an expansion of added servers enhanced with the IP Anycast technology, the servers are now based in such countries as Japan (three servers in Tokyo), Korea (Seoul), France (Paris) and U.S. (San Francisco). They have been jointly operated by WIDE and JPRS through assistance and cooperation from IXs and ISPs.
The M-Root DNS server acquired the IPv6 address in 2003 ahead of any other Root DNS servers in the world.Through various experiments, the IPv6 address of the M-Root DNS server, 2001:dc3::35, is finally registered as an AAAA record in the root zone, offering a DNS query to the root zone solely operating in IPv6. While IPv4 is facing its address exhaustion that is likely to surface in about two years, the IPv6 address registration of the M-Root DNS server is expected to promote further deployment of IPv6.
The WIDE Project and JPRS will continuously and jointly work in cooperation with other domestic and international DNS server operators to achieve further development and to provide greater operational stability for the Internet in accordance with the demands of the Internet community and society.
* Root DNS server:
A group of name servers that maintain the information stored at the top most level in the hierarchy of the Domain Name System (DNS). The Root DNS servers have 13 host names ranging from A.ROOT-SERVERS.NET to M.ROOT-SERVERS.NET. Their task is to provide the core information that makes all kinds of domain naming available on the Internet.

* IANA (Internet Assigned Numbers Authority)
IANA is currently operated by ICANN. The tasks of IANA include allocation and management of the Internet addresses and numbers used in various Internet protocols in addition to DNS root zone management. It is also responsible for IPv4/IPv6 address allocation to the regional registries such as APNIC.
* ICANN (The Internet Corporation for Assigned Names and Numbers)
ICANN is a non-profit corporation established in October 1998, with the goal of coordinating and managing the Internet resources globally. The tasks of ICANN include allocation of IP (Internet Protocol) address space, assignment of protocol identifiers, name system management for gTLD (generic Top-Level Domain) and ccTLD(country code Top-Level Domain) and system administration of root servers.
* AAAA record (a quad-A record)
An AAAA record is a DNS record used to specify an IPv6 address associated with the domain name (See RFC3596). A DNS cache server may also look up AAAA records of other DNS servers to submit DNS queries in IPv6.
* Japan Registry Services Co., Ltd.(JPRS)
JPRS was incorporated on December 26, 2000 to carry out responsibility of the management and administration of the .JP top-level domain and to operate the domain name system. As a company dedicated to maintaining the Internet infrastructure, JPRS contributes to the development of the Internet and building of a better future for everyone.
* WIDE Project
WIDE (Widely Integrated Distributed Environment), established in 1988, is a research consortium that promotes the research and development of Internet technologies. Over 100 corporations and 40 universities are currently involved in the WIDE Project, partaking in a wide array of research and development activities.
