If you’re facing a DNS leak in Windows 10, it means your online activities might be exposed, defeating the purpose of using a VPN. Fixing a DNS leak involves adjusting your VPN settings, tweaking your network configurations, and sometimes modifying system files. This guide will take you through each step with easy-to-follow instructions so you can stay secure online.
How to Fix DNS Leak Windows 10
The following steps will help you identify and fix any DNS leaks on your Windows 10 machine, ensuring your internet activity remains private and secure.
Step 1: Verify the DNS Leak
Before you fix it, you need to confirm if you have a DNS leak.
Open your web browser and visit a DNS leak test website, such as dnsleaktest.com or ipleak.net. Run a standard test to see if your real DNS server is exposed.
Step 2: Change DNS Settings
Step 2: Change DNS settings to a more secure provider.
Go to Control Panel > Network and Internet > Network and Sharing Center > Change adapter settings. Right-click your network connection and select Properties. Select "Internet Protocol Version 4 (TCP/IPv4)" and click Properties. Choose "Use the following DNS server addresses" and enter a secure DNS, like 8.8.8.8 (Google DNS).
Step 3: Adjust VPN Settings
Step 3: Ensure your VPN is configured to prevent DNS leaks.
Open your VPN application and navigate to its settings. Look for a feature that explicitly mentions DNS leak protection and enable it. If your VPN doesn’t have this feature, you might want to consider switching providers.
Step 4: Disable Smart Multi-Homed Name Resolution
Step 4: Disable a Windows feature that can cause DNS leaks.
Open the Local Group Policy Editor by typing "gpedit.msc" in the Start menu. Navigate to Computer Configuration > Administrative Templates > Network > DNS Client. Double-click "Turn off smart multi-homed name resolution" and set it to "Enabled".
Step 5: Flush DNS Cache
Step 5: Clear the DNS cache to remove any old or incorrect DNS entries.
Open Command Prompt as an administrator. Type the command ipconfig /flushdns and press Enter. This will clear any cached DNS entries, helping to resolve any DNS leak issues.
Step 6: Test Again
Step 6: Verify the fix by running another DNS leak test.
Go back to the DNS leak test site you used in Step 1 and run the test again. Ensure that only your VPN’s DNS servers show up.
After completing these steps, your Windows 10 machine should no longer be leaking DNS requests, ensuring your online activities remain private and secure.
