IPv6 Network - Windows

Real IPv6 support in Windows started with Windows XP.3 In the initial release, IPv6 wasn’t available through the graphical user interface but only by using a somewhat hidden command that must be entered using the command line: ipv6 install
Removing IPv6 is done with ipv6 uninstall. The ipv6.exe command is now deprecated, and Microsoft encourages you to use netsh interface ipv6 install or ...uninstall instead. Because ipv6.exe’s syntax is completely unfathomable, it’s best to use netsh interface ipv6 for all other purposes, but it’s hard to beat the succinct elegance of “ipv6 install.” As of Service Pack 1, IPv6 can also be installed and removed as an additional protocol called “Microsoft IPv6 Developer Edition” in the network setup. In April 2003, Microsoft released the Advanced Networking Pack for Windows XP, which includes additional IPv6 features. The update is distributed through Windows Update, but if you’re not sure you have it installed, you can go to http://support.microsoft.com/ and select “Knowledge Base Article ID Number Search” (the URL is too hideous to repeat in print) and enter article number 817778. The Knowledge Base article discusses the update at length and includes instructions on downloading and installing it (but these pretty much boil down to “Use Windows Update”). After installing the update, IPv6 is available as an additional protocol under the name “Microsoft TCP/IP version 6.” You can install it by selecting Start ➤Control Panel ➤Network and Internet Connections ➤Network Connections and then right-clicking any network interface and selecting Properties,

Note When Internet sharing is configured, which is almost unavoidable if you allowed Windows to “set up or change your home or small office network,” some network interfaces may be bridged. In that case, the IPv6 protocol can’t be added to the bridged interfaces themselves, only to the “Network Bridge” virtual bridging interface.

After installing the IPv6 protocol for any interface, the system will configure link-local addresses and also try to configure global addresses on all interfaces. (See Chapter 3 for details.) If you don’t want to have IPv6 enabled on one or more interfaces, it is possible to disable the protocol on a per-interface basis by clearing the checkbox in the “this connection uses the following items” part of the Properties window for an interface.

IPv6 is available as a downloadable preview for Windows 2000, and an IPv6-capable version of Trumpet Winsock is available for Windows 98
