NTT Com to Offer IPv4/IPv6 Dual-stack Corporate VPN

TOKYO, JAPAN - NTT Communications Corporation (NTT Com) announced today that it will launch an Internet-protocol (IP) virtual private network (VPN) service that supports both conventional IPv4 and next-generation IPv6 protocols for enterprise customers in Japan, beginning March 23.

This will be the country’s first commercial IPv6-compatible IP-VPN service based on Multi-protocol Label Switching (MPLS).

The IPv4/IPv6 dual-stack connectivity will be available as an option for Arcstar™ IP-VPN services. It will enable both IPv4 and IPv6 to be used on a single network, allowing enterprise customers to continue using IPv4 while introducing IPv6 for a relatively low cost.

With IP addresses nearing exhaustion in the IPv4 world, there is a growing need for enterprise network services that are compatible with IPv6, the next-generation Internet protocol that offers a massive capacity for new addresses as well as enhanced network security.

NTT Com began providing Arcstar IP-VPN with IPv6 connectivity on a trial basis in September 2007. It will now apply the know-how and experience gained during the trial toward its commercial dual-stack service.

Arcstar IP-VPN have been Japan’s most popular corporate IP-VPN service for seven consecutive years, according to a survey conducted by Nikkei Communications magazine in September 2008.
