IPv6 Configuration Policy

This policy configures IPv6 on network interfaces. By default, Windows 7, Windows Server 2008 and Windows Vista enable and use IPv6 as the default protocol.

If you enable this policy, you can specify how Windows uses IPv6. To fully disable IPv6 functionality, select "Disable all IPv6 components." Other settings disable IPv6 on specific interfaces.

Note: You cannot disable IPv6 on the loopback adapter.

If you disable this policy, IPv6 will be fully enabled on the computer.

If you do not configure this policy, IPv6 settings will not be configured or enforced and the computer will continue to use its current configuration. Read the note about preferences below.
