Enabling DNS over HTTPS (DoH) in Windows 11: A Comprehensive Guide

DNS over HTTPS (DoH) is a method of encrypting your DNS queries, enhancing your online privacy and security. Unlike traditional DNS, which sends your queries in plain text, DoH encrypts them using HTTPS, making it more difficult for eavesdroppers to see which websites you're visiting. This guide will walk you through enabling DoH in Windows 11, explaining different methods and considerations.

Why Use DNS over HTTPS?

• Enhanced Privacy: DoH protects your DNS queries from being intercepted by your ISP or other network observers.
• Improved Security: Encryption prevents DNS spoofing and other attacks that could redirect you to malicious websites.
• Faster Resolution (Potentially): Some DoH providers offer faster name resolution than traditional DNS servers.
• Censorship Resistance: In some regions, DoH can help bypass censorship efforts targeting DNS resolution.

Methods for Enabling DoH in Windows 11

1. Using Your Router's DoH Settings (Recommended)

The most effective way to enable DoH is through your router. This ensures all devices connected to your network benefit from DoH encryption. Consult your router's documentation for instructions. Many modern routers have built-in support for DoH, allowing you to specify a provider like Cloudflare (1.1.1.1) or Google (8.8.8.8) or Quad9 (9.9.9.9).

2. Using a Third-Party DNS Client

Several third-party DNS clients offer DoH functionality. These clients often provide additional features like ad blocking and privacy enhancements. Popular options include:

• AdGuard: A comprehensive privacy solution with DoH support.
• NextDNS: A highly customizable DNS service with advanced features.
• Simple DNSCrypt: Focuses on DNS encryption and privacy.

Download and install your chosen client, following its instructions for configuring DoH.

3. Modifying the Registry (Advanced Users Only)

Warning: Modifying the Windows Registry incorrectly can cause serious system problems. Proceed with caution and back up your registry before making any changes. This method is generally not recommended unless other options have failed.

You can manually configure DoH by modifying the Windows Registry. This method requires creating a new DWORD value and setting its data to the address of your chosen DoH provider. However, this approach is not as reliable as using your router or a dedicated client and could be overwritten by Windows updates. Detailed instructions are available online, but thorough research is crucial before attempting this.

Choosing a DoH Provider

Several reputable DoH providers are available. Consider factors such as privacy policy, security features, and performance when making your selection. Popular choices include:

• Cloudflare (1.1.1.1): Known for its speed and privacy-focused policies.
• Google Public DNS (8.8.8.8): A widely used and reliable option.
• Quad9 (9.9.9.9): Focuses on security and blocking malicious domains.

Troubleshooting

If you encounter issues after enabling DoH, check the following:

• Correct Provider Address: Ensure you've entered the correct DoH provider address.
• Firewall/Antivirus Interference: Temporarily disable your firewall or antivirus software to see if it's blocking DoH connections.
• Network Configuration: Verify your network connection and settings.
• Router Settings: If using your router, double-check its DoH configuration.

Enabling DoH significantly enhances your online privacy and security. Choose the method that best suits your technical skills and network setup. Remember to research your chosen DoH provider's privacy policy to understand how they handle your DNS data.
