How to Change DNS in Windows 11 for Better Speed and Security

Changing your DNS (Domain Name System) settings in Windows 11 can improve your internet browsing speed, enhance security, and give you more control over your network connections. Whether you’re experiencing slow load times, want to block certain sites, or prefer using a privacy-focused DNS provider, customizing your DNS settings is a straightforward process. Before you begin, ensure you have the DNS server addresses you want to switch to, which can be obtained from providers like Google DNS, Cloudflare, or OpenDNS. Having administrator access on your Windows 11 device is also necessary to make these changes.

What You’ll Need

  • Windows 11 device with administrative access
  • Internet connection
  • Preferred DNS server addresses (e.g., Google DNS: 8.8.8.8 and 8.8.4.4)

Step-by-Step

  1. Open the Settings app by clicking on the Start menu and selecting the gear icon, or press Windows + I on your keyboard.
  2. In the Settings window, click on ‘Network & internet’ from the sidebar.
  3. Scroll down and select ‘Advanced network settings.’
  4. Click on ‘Network and Sharing Center’ under the ‘Related settings’ section.
  5. In the new window, find your active network connection (Wi-Fi or Ethernet), right-click it, and select ‘Properties.’
  6. In the list of items used by the connection, scroll down to find ‘Internet Protocol Version 4 (TCP/IPv4),’ select it, then click the ‘Properties’ button.
  7. In the new window, select ‘Use the following DNS server addresses.’
  8. Enter your preferred DNS server addresses in the fields provided. For example, for Google DNS, input 8.8.8.8 as the Preferred DNS server and 8.8.4.4 as the Alternate DNS server. You can also use Cloudflare (1.1.1.1 and 1.0.0.1) or OpenDNS (208.67.222.222 and 208.67.220.220).
  9. Click ‘OK’ to save your changes, then close all remaining windows.
  10. To ensure the changes take effect, you might need to restart your computer or disable and enable your network connection.

Common Mistakes

  • Not entering the DNS addresses correctly, leading to connection errors.
  • Forgetting to select ‘Use the following DNS server addresses’ before inputting new ones.
  • Changing DNS settings on the wrong network adapter, especially if multiple connections are present.
  • Not saving the settings properly, which results in reverting to default DNS servers.
  • Forgetting to restart the network connection or computer to apply changes.

Tips

  • Always note your original DNS settings before making changes, so you can revert if needed.
  • Use reputable DNS providers to enhance browsing speed and security.
  • Consider setting different DNS servers for Wi-Fi and Ethernet connections if you use both.
  • Use the command prompt command ‘ipconfig /flushdns’ after changing DNS to clear cached DNS data.
  • Test your new DNS settings by visiting websites or using online DNS testing tools.

Troubleshooting

If your internet connection stops working after changing DNS settings, or you experience slow browsing, try these steps:

  • Revert to your original DNS settings by following the same steps and selecting ‘Obtain DNS server address automatically.’
  • Restart your computer and router to refresh network configurations.
  • Check for typos in the DNS addresses entered; even a small mistake can cause connectivity issues.
  • Disable any VPNs or security software temporarily to see if they interfere with DNS resolution.
  • Use the Windows Network Troubleshooter by right-clicking the network icon in the taskbar and selecting ‘Troubleshoot problems.’
