Maximizing use of the product
6
Using in the IPv6 environment
The product supports “IPv6” (Internet Protocol
Version 6), an Internet protocol of the next
generation. As IPv6 inherits functions related to
traditional “IPv4”, you can use the new protocol
without affecting the existing network.
NOTE
If your provider does not support IPv6, you cannot
connect to the Internet in the IPv6 environment.
Confirm in advance whether your provider provides
an IPv6 connection service.
Before introducing
IPv6
To use both the IPv6 and IPv4
environments
IPv6 is not compatible with IPv4. To mix those two
protocols on a network, therefore, a mechanism
generally called “transition mechanism” is required.
Multiple steps are usually required for transition
from IPv4 to IPv6, and an appropriate transition
technology is required for each step.
As transition technologies, the product supports
“IPv6 over IPv4 tunneling” for connecting an IPv6
network via an IPv4 network, and “IPv4 over IPv6
tunneling” for connecting an IPv4 network via an
IPv6 network.
Check configuration information
from the provider
When you contract an IPv6 connection service, the
provider provides the following information:
• Prefix (Address block)
• Connection method (native connection/dual-
stack connection/tunnel connection)
• Tunnel terminal address (for tunnel connection)
• Routing control method (whether to use RIPng.
RIPng is not used unless specifically described.)
• Method to check connection (address of the other
side of ping, website to be browsed, etc.)
Introducing IPv6 into
PCs
Introduce IPv6 in a Windows 7 or
Windows Vista environment
Windows 7 and Windows Vista can use IPv6
without additional settings.
