Our involvement with IPv6
KDDI is planning to implement IPv6 for various services for corporate customers and individual customers. KDDI will release information about this as needed.
KDDI is also actively converting KDDI Web Site (www.kddi.com) to the IPv6 compatible connectivity.
Sub domains of kddi.com will be gradually converted to the IPv6 connectivity.
Information on converted domains will be posted on this page.
Domains already converted to the IPv6 connectivity
Posted on: As of July 16, 2009
Certain contents in the KDDI Web Site are connected to a domain different from kddi.com for viewing. Thus, even inside the KDDI Web Site, some contents are not shown if connected in IPv6. Please keep this in mind.
