Support for Internet Protocol version 6 (IPv6), a new suite of standard protocols for the Network layer of the Internet, is built into the latest versions of Microsoft Windows, which includes Windows XP, although it is not installed by default. If you are running Windows XP prior to Service Pack 2, you will either need to update your system to the latest service pack or install the "Advanced Networking Pack" for Windows XP. Here is the link to read more about this topic as well as to access the download from the Microsoft web site: http://support.microsoft.com/kb/817778.
IPv6 is designed to solve many of the problems of the current version of IP (known as IPv4) such as address depletion, security, autoconfiguration, and extensibility. Its use will also expand the capabilities of the Internet and enable a variety of valuable and exciting scenarios, including peer-to-peer and mobile applications.
Since IPv6 is not installed by default on Windows XP computers, you will need to install it manually. There are two methods for installing this protocol. You can either install the protocol from the adapter's properties windows or install it via the command prompt.
To install it via the properties windows follow these steps. The first step is to access the adapter's properties and click on Install.
Next, select the network component type. In this case, click on Protocol, then click Add.
Finally, choose "Microsoft TCP/IP version 6".
If the protocol has successfully installed, your adapter's properties windows should now list the new protocol.
How to install and uninstall IPv6 using command line.
To install IPv6:
Start, point to All Programs, point to Accessories, and then click Command Prompt.
At the command prompt, type:
ipv6 install [press the Enter Key].
To uninstall IPv6:
Start, point to All Programs, point to Accessories, and then click Command Prompt. At the command prompt, type:
