NTT Communications Group to Join World IPv6 Day Trial

TOKYO, JAPAN - NTT Communications (NTT Com) and its three subsidiaries of NTT Plala, NTT PC Communications and NTT America jointly announced today that they will participate in World IPv6 Day, a worldwide testing of IPv6 protocol to demonstrate its readiness to ensure successful transition from IPv4 environment.

Sponsored and organized by the Internet Society (ISOC) and major content providers such as Google and Facebook, the event is a 24-hours testing of public IPv6 deployment starting 00:00 UTC on June 8, 2011. Participants will enable IPv6 on their main Websites for 24 hours, providing their Web content over IPv6 while testing connections to isolate any possible issues that may affect users in IPv6 environment.

NTT Communications Group has been a leading contributor to the IPv6 deployment ever since the company helped the Internet Engineering Task Force (IETF) to establish the IPv6 basic protocol in 1995, and participated in a number of projects led by respective governments including the IPv6 Information Appliance Trial in Japan and 6NET hosted by the EU. The NTT Com Group is also noted for launching the world's first commercial IPv6 service in 2001, OCN IPv6 Tunnel Connection Service in Japan.

Today, IPv6 technologies are deployed in various content delivery services of NTT Com Group, including NTT Com's emergency earthquake news flash and NTT Plala's Hikari-TV with 1.4 million subscribers, to name a few. Overseas, NTT Com's global backbone was the first network of its kind to offer a commercial dual-stack IPv6 transit service, initially in the United States and later globally. The company's highly experienced IPv6 engineers remain in the forefront of IPv6 implementation.

At a news conference on February 3, 2011 in Miami, Florida, the Internet Corporation for Assigned Names and Numbers (ICANN) joined the Number Resources Organization (NRO), the Internet Architecture Board (IAB) and the Internet Society in announcing that the pool of first generation Internet addresses has now been completely emptied. During the conference, Rod Beckstrom, President and CEO of ICANN mentioned NTT as a telco leading the charge and adopting IPv6 to move to the new protocol.
