What is Secure DNS in Chrome?

Secure DNS encrypts DNS queries, making it difficult for attackers to intercept or manipulate them. Instead of sending plain-text DNS requests, Chrome routes them through an encrypted connection to a trusted DNS provider.

How to Enable Secure DNS in Chrome?

To enable Secure DNS in Google Chrome, follow these steps:

1. Open Chrome and go to chrome://settings/security.

2. Scroll down to the Advanced section.

3. Find the Use Secure DNS option and toggle it on.

4. Choose one of the following options:

• With your current service provider (if supported)

• Select a custom provider, such as:

• Google DNS (8.8.8.8, 8.8.4.4)

• Cloudflare DNS (1.1.1.1)

• OpenDNS (208.67.222.222, 208.67.220.220)

• Quad9 (9.9.9.9)

5. Close settings and Chrome will now use encrypted DNS queries.

Why Use Secure DNS in Chrome?

Secure DNS offers several key advantages:

• Increased Privacy: Prevents ISPs and third parties from monitoring browsing history.

• Improved Security: Protects against DNS spoofing, phishing, and man-in-the-middle attacks.

• Faster Browsing: Some DNS providers offer optimized query resolution, leading to quicker page loads.

• Reliability: Trusted Secure DNS providers ensure more consistent and error-free connections.

How to Check if Secure DNS is Working?

After enabling Secure DNS, visit https://1.1.1.1/help or https://dns.google/ to verify if DoH is active.

Alternatively, you can check Chrome's internal settings:

1. Type chrome://net-internals/#dns in the address bar.

2. Press Enter and review active DNS settings.

Troubleshooting Secure DNS Issues

If Secure DNS is not working correctly:

• Ensure Chrome is updated to the latest version.

• Disable conflicting VPNs or proxy settings.

• Try switching to a different Secure DNS provider.

• Restart the browser and flush the DNS cache (chrome://net-internals/#dns).

Conclusion

Enabling Secure DNS in Chrome enhances online security and privacy by encrypting DNS queries. It is a simple yet effective way to prevent tracking and DNS-based attacks while improving browsing reliability. Users should configure Secure DNS with a trusted provider for the best experience.
