Appendix E IPv6
to forward packets between 6to4 routers in an IPv4 Internet and an IPv6 device
(Z) on the IPv6 Internet.
To transmit packets, a 6to4 address is used with a special IPv6 prefix of 2002:: to
encode a given IPv4 address. A 6to4 address has the following format:
2002:IPv4 address:subnet ID:host ID/64
For example, if you have an IPv4 address of 192.168.1.1 (first converted to binary notation
and then to the colon hexadecimal representation of
2002:c0a8:0101::1/64
Example - Enabling IPv6 on Windows XP/2003/Vista
By default, Windows XP and Windows 2003 support IPv6. This example shows you
how to use the ipv6 install command on Windows XP/2003 to enable IPv6. This
also displays how to use the ipconfig command to see auto-generated IP
addresses.
C:\>ipv6 install

Succeeded.

Windows IP Configuration
Ethernet adapter Local Area Connection:
IPv6 is installed and enabled by default in Windows Vista. Use the ipconfig
command to check your automatic configured IPv6 address as well. You should
see at least one IPv6 address available for the interface on your computer.
Example - Enabling DHCPv6 on Windows XP
Windows XP does not support DHCPv6. If your network uses DHCPv6 for IP
address assignment, you have to additionally install a DHCPv6 client software on
your Windows XP. (Note: If you use static IP addresses or Router Advertisement
for IPv6 address assignment in your network, ignore this section.)
