How to properly Enable or Disable IPv6 in Windows 11/10

Till recently, we used the IPv4 translation, which provided us with a 32-bit address. But these available addresses will be exhausted soon. The newer version of IP, is the IPv6, on the other hand, offers us 128-bit addressing capability, which means that there would be more addresses available for habit and making the Internet more fasten ( better network layer security ) than the earlier adaptation of the IPv4, with a better QoS and other features such as Mobility support, multi-casting defend angstrom well. IPv6, the successor to the protocol presently used on the Internet, was designed in the late 1990s but has not seen deployment on a global scale. With IPv4 address space running out, the industry can not afford to wait much longer. now on or after World IPv6 Launch, i.e., beginning June 6, 2012, many websites will permanently enable IPv6 connectivity to their websites. Most Windows users may not even notice the shift. If you have no IPv6 connectivity, you will continue to connect as ahead. If you happen to have IPv6 connectivity, your connectivity to participating websites will mechanically shift to IPv6. You can test your IPv6 connectivity here .

Force Windows to use IPv4

If you are facing issues while connecting to the Internet or specific sites, due to this reason, you can resolve your Internet connectivity issues using these Fix It ’ s from Microsoft.

By nonpayment, Windows prefers IPv6 over IPv4. so if you are having problems using IPv6 to connect to some websites, you can configure your Windows to select IPv4 alternatively of IPv6 .

  • The Prefer IPv4 over IPv6 Microsoft Fix it 50410 will configure your computer to use IP4 instead of IPv6.
  • If you wish to reverse it anytime, you can use the Prefer IPv6 over IPv4 Microsoft Fix it 50441 to make your Windows go back to its defaults.

Enable or Disable IPv6 and IPv4 in Windows

If for some reason, you wish to disable IPv6, it can be disabled either through the DisabledComponents register measure or through the checkbox for the Internet Protocol Version 6 ( TCP/IPv6 ) component in the list of items on the Networking tab key for the Properties of connections in the Network Connections folder viz. Control Panel\Network and Internet\Network Connections. You besides have the options to Uninstall, Install or modify their Properties here.

alternatively, you can besides use the comply Fix-Its from Microsoft to do the job for you. At KB929852, you will find a good number of Fix Its that will allow you to :

  1. Disable IPv6
  2. I prefer IPv4 over IPv6
  3. Disable IPv6 on non-tunnel interfaces
  4. Disable IPv6 tunnel interfaces
  5. Disable IPv6 on non-tunnel interfaces (except the loopback) and IPv6 tunnel interface
  6. Enable IPv6
  7. Prefer IPv6 over IPv4
  8. Enable IPv6 on non-tunnel interfaces
  9. Enable IPv6 tunnel interfaces
  10. Enable IPv6 on non-tunnel interfaces and IPv6 tunnel interfaces.

Correct way to disable IPv6, and avoid 5 second Boot delay

UPDATE: New discover shows the correct way to disable IPv6 on Windows systems and avoid a 5 second Boot stay. Microsoft has disclosed the adjust respect for the DisabledComponents register key. many Windows users and IT administrators have opted to disable IPv6 to solve Internet connectivity issues, or on the presumption that they are not running any applications or services that use it. Yet others have disabled it because they feel that having both IPv4 and IPv6 enabled, effectively doubled their DNS and Web traffic. Microsoft explains that this is far from the truth. It goes on to explain what are the caller ’ s recommendations about disabling IPv6. But first, let us divert our attention to these standards.

IPv4 is the fourth version in the development of Internet Protocol Internet that routes most dealings on the Internet. The version provides us with a 32-bit address. The newer version of IP, that is the IPv6, on the other hand, offers us 128-bit addressing capability which means that there would be more addresses available for habit and making the internet more secure. Check this post to learn more about the remainder between IPv4 and IPv6.

IPv6 is a compulsory part of the Windows engage system and it is enabled. Microsoft says its Windows OS was designed specifically with IPv6 present. If IPv6 is disabled on Windows 7 or upper berth versions, some components such as Remote Assistance, HomeGroup, DirectAccess, and Windows Mail may actually fail to function. The problem gets compounded with a delay in the inauguration prison term of 5 seconds or more if IPv6 is disabled .

Disabling IPv6 delayed boot times by 5 seconds

For years, the method practiced regularly to disable IPv6 was setting the DisabledComponents value at 0xFFFFFFFF under the follow register key :


however, disabling IPv6 with the above register value caused a 5-second boot delay in the Pre-Session Init Phase of OS inauguration .

The rationality for the delay is that underlying code requires the upper 24-bits to be zero. Since the upper 24-bits have no entail, setting a value of 0xFF is functionally identical to the 0xFFFFFFFF arrange. unfortunately, the DisabledComponents setting got documented with an all “ F ” bitmask. If you used this attested put this unnecessarily results in a 5 irregular boot delay, says Microsoft .

The Windows versions impacted by the 5-second boot delay include Windows Vista, Windows 7, Windows 8, Windows 8.1, Windows Server 2008, Server Windows Server 2008 R2, Windows Server 2012, and Windows Server 2012 R2. now a 5-second boot delay may not matter on servers that rarely reboot, but on customer operating systems, particularly those that are configured with SSD disk drives where full OS kick times are approaching 30 seconds – it does matter ! Leaving IPv6 enabled on stream Windows client and waiter operating systems remains the best practice configuration. But if you do wish to disable IPv6, the chastise set to use in environments that legitimately need to disable IPv6 and IPv6 transition technologies is to configure the DisabledComponents register key with a value of 0xFF, says Microsoft now. If you have disabled IPv6 by setting DisabledComponents at 0xFFFFFFFF, it might be a good idea to make the exchange based on these new findings .

Disable IPv6 via Network Properties

You can besides follow this method acting to disable IPv6 :

  1. Click on Windows Search bar and search for Control Panel.
  2. When Control Panel opens, navigate to Network and Internet.
  3. Then, click on Network and Sharing Center, and after that click on Change Adapter Settings.
  4. At the Network Connections window, double click on the option Wi-Fi network adapter.
  5. After that, click on Properties.
  6. From the list, uncheck the box beside IPv6 and finally click OK.

Both the Fix-It and the manual steps mentioned in KB929852 have been updated to reflect this change. It is always a good idea to create a system restore point before making any changes to your system.

I hope this article helps those who may be facing connectivity issues .

Why does my IPv6 have no Internet access?

It normally happens when you have an outdated driver or incorrectly DNS and faulty HT mode. You may besides need to run the Network troubleshooters and reset Winsock to fix the problem. If you have recently moved from IP4 to IP6, make sure to get it configured correctly .

Which problem does IPv6?

While IPv6 is an improvement over IPv4, but similar to how IPv4 was optimized, the exact needs to be done with IPv6. While it is faster, it besides carries a distribute of data. Things will get good as the adoption increases .
