How to Change DNS Server Settings on Windows 11

Changing your DNS server settings on Windows 11 can improve your browsing speed, enhance security, or access region-restricted content. Whether you’re troubleshooting connectivity issues or customizing your network preferences, updating your DNS can make a significant difference. Before starting, ensure you have the DNS server addresses you want to use, such as Google DNS (8.8.8.8 and 8.8.4.4) or Cloudflare DNS (1.1.1.1). This guide provides a clear, step-by-step process to modify DNS settings on Windows 11, along with helpful tips, common mistakes to avoid, troubleshooting advice, and FAQs to clarify any doubts.

What You’ll Need

• A Windows 11 PC with administrative access
• The DNS server addresses you wish to use (e.g., Google DNS, Cloudflare DNS)
• An active internet connection

Step-by-Step

1. Open the Settings app by clicking the Start menu and selecting the gear icon, or press Windows + I on your keyboard.
2. In the Settings window, click on “Network & internet” in the sidebar.
3. Click on “Advanced network settings” at the bottom of the page.
4. Under “More settings,” select “Network and Sharing Center” to open the classic Control Panel network settings.
5. In the Network and Sharing Center, find your active network connection (Ethernet or Wi-Fi), then click on its name or icon.
6. Click the “Properties” button in the connection status window.
7. In the list of items, scroll down and select “Internet Protocol Version 4 (TCP/IPv4),” then click “Properties.”
8. In the new window, select “Use the following DNS server addresses.”
9. Enter your preferred DNS server address in the “Preferred DNS server” field (e.g., 8.8.8.8).
10. Enter your alternate DNS server address in the “Alternate DNS server” field (e.g., 8.8.4.4).
11. Click “OK” to save your settings, then close all remaining windows.
12. To apply the changes, restart your network connection or restart your computer.

Common Mistakes

• Entering incorrect DNS server addresses, leading to connectivity issues.
• Forgetting to select “Use the following DNS server addresses” before inputting new addresses.
• Modifying DNS settings on the wrong network adapter, especially if multiple network interfaces are present.
• Not restarting the network connection or computer after making changes, which can prevent settings from taking effect.
• Using DNS servers that are blocked or unreliable in your region.

Tips

• Always double-check the DNS addresses before applying changes to avoid typos.
• Use reputable DNS providers like Google, Cloudflare, or OpenDNS for better security and speed.
• If you experience issues, revert to automatic DNS settings to restore connectivity quickly.
• Consider setting DNS on your router if you want all devices on your network to use the same DNS server, simplifying management.
• Update your DNS settings periodically to ensure optimal performance.

Troubleshooting

If your internet connection stops working after changing DNS settings, follow these steps:

• Revert to automatic DNS by selecting “Obtain DNS server address automatically” in the network properties.
• Restart your computer or disable and re-enable your network adapter.
• Flush your DNS cache by opening Command Prompt as administrator and typing ipconfig /flushdns, then pressing Enter.
• Check if the DNS server addresses are correct and reachable by pinging them from Command Prompt (e.g., ping 8.8.8.8).
• Disable any VPNs or firewalls that might interfere with DNS resolution temporarily to test if they are causing the issue.
• If problems persist, try switching to different DNS servers or resetting your network settings.
