2 ways to disable IPv6 on Windows

Here in this tutorial, we'll discuss about how to easily disable IPv6 on Windows 10.

With IPv6 we have the capability to assign an unique IP address to every internet connected device. However sometimes improper IPv6 configuration leads to complication and security issue.

As an example, while using a VPN service on Windows, I ran into the an issue, lack of proper IPv6 support and unavailability of IPv6 capable OpenVPN servers. So, I had to disable IPv6 to avoid IPv6 leak and other complications.

Without further ado, let's jump into the main topic.

Disable Ipv6 on Windows 10 from Network and Internet settings

There's various method available on Windows to disable IPv6. The easiest of them to open the Network and sharing center and change the adapter settings.

To disable ipv6 on Windows 10, right click on the network icon and select Open Network and Internet Settings option.

Then select the Change adapter options from this settings window, screenshot attached below.

After select that, the network connection settings will appear, here you've to select individual adapters and right click over them to get the properties option.

From the properties option, scroll down to find the Internet Protocol Version 6 (TCP/IPv6) check box. Now uncheck this tick box and hit the OK button at the bottom.

Finally disconnect the the network connection if it's connected, and re-connect if required. That's all you need to do to disable IPv6 on Windows.

Disable IPv6 on Windows using PowerShell

To disable IPv6 on Windows using the command line, You can use the PoweShell commands.

First open up Windows PowerShell as administrator and use the Get-NetAdapter command to get all available network interfaces.

Note:- PowerShell commands are case insensitive, you can type either in lowercase or upper case or mix both, but it's recommended to stick with proper commands.

So, here you have an overview of all the available network interfaces. To get more details and IP binding to all the available interfaces, use the Get-NetAdapterBinding binding command.

After recognising the your desired networking adapter interface and IP binding, use the Disable-NetAdapterBinding command to disable particular type of binding, either IPv4 or IPv6, is this case we will only disable ipv6 on windows 10.

As an example I want to deactivate IPv6 on the Wi-Fi 2 interface. For that, I've to use the the PowerShell command listed below.

Disable-NetAdapterBinding -name 'Wi-Fi 2' -ComponentID ms_tcpip6 -PassThru

You can use the wildcard * to disable ipv6 on all the interfaces instead of the single one.

To re-enable, you've to use the Enable-NetAdapterBinding command, an example below.

Enable-NetAdapterBinding -name * -ComponentID ms_tcpip6 -PassThru

Conclusion

Obviously it's not a good idea to block ipv6 connections for no reason. The reason I had to deactivate IPv6 is few problems with IPv4 only VPN and proxies.

So, it's fairly easy to disable IPv6 on Windows using these two methods mentioned above. Hope this quick tutorial is helpful, if you've any suggestion or question, just drop a comment below.
