Information on Commercial IPv6 Connectivity Services in Japan

Prepared by: Mark Brown (Japan)

Summary

This flimsy presents summary information on IPv6 connectivity services available in Japan. It is made available to support the report on TCP/IP being prepared by SGN01.

- 1 - 1. Introduction

In 2003, NTT Communications of Japan and its Internet services provider arm OCN introduced IPv6 services aimed at business users. This flimsy presents summary information on these services as input to WGN SGN01’s current study on the use of TCP/IP for aeronautical telecommunication. The material presented is summarised from information available from NTT’s web pages.
