How to Disable IPv6 in Windows 8 and Windows 8.1

IPv6 is the imminent next evolution of the Internet protocol, but it can cause problems with legacy equipment and DNS in certain environments. Disabling IPv6 is an easy way to fix certain network issues with Windows machines. If you’re not experiencing problems, there’s no reason to disable IPv6. Otherwise, it’s easy to turn on and off by editing the Windows registry. Let’s check it out.


Unfortunately, IPv6 isn’t disabled by editing the properties of a network adapter. Simply unchecking the box doesn’t work. A registry hack is needed (This also works with Window 7).

Enter DisabledComponents into the Name field

Double click on the new DisabledComponents value, enter ffffffff into the Value data dialog box, and click theOK button

Confirm the new registry value contains the required data.

Edit DWORD (32-bit) Value SAS

That’s it. After restarting the computer, IPv6 will be disabled

Verify that IPv6 is disabled by running ipconfig /all from the command prompt. The output should only show IPv4 addresses and no 6to4 adapters.

IPv6 can be enabled by either deleting the DisabledComponents registry value or changing its data to 0.
