Most ISPs are in the process of enabling the IPv6 protocol which is then available for usage in addition to the currently used IPv4 protocol. Windows Vista and Windows 7 users do not need to enable or configure their operating system for IPv6 usage as it is enabled by default. The situation is different for Windows XP users who need to install the IPv6 protocol to add support for it to the operating system.

It is probably a good idea to test if IPv6 is already available on the operating system. An easy option to find out is the ipconfig command which displays network information in a command line window. To run the command press Windows-R, type cmd and hit enter. This opens the Windows command prompt. Now use the command ipconfig to find out if IPv6 is available on the computer. Please note that the following screenshot is showing ipconfig on Windows 7.

If you do not see an entry IPv6 Address in the listing it is not enabled and needs to be installed. The easiest way to install the IPv6 protocol under Windows XP is from the command prompt. Enter the following commands separately and press return after each of them:

  • netsh
  • interface
  • ipv6
  • install

This installs IPv6 under Windows XP. It is also possible to install the protocol under the network settings options of the Control Panel. Right-click on the appropriate network adapter and select Preferences from the selection. Now select Install on the screen and then Protocol from the available options. Locate Microsoft TCP/IP Version 6, a click on OK installs the selected protocol.
