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

DNS over HTTPS (DoH) enhances your online privacy and security by encrypting your DNS queries. Instead of sending your DNS requests in plain text (which can be intercepted), DoH sends them over HTTPS, the same protocol used for secure websites. This prevents your ISP or other network observers from seeing which websites you're visiting.

Why Use DNS over HTTPS?

• Enhanced Privacy: Your DNS queries are encrypted, protecting them from eavesdropping.
• Improved Security: DoH helps prevent DNS spoofing and other attacks that can redirect you to malicious websites.
• Faster Connections (Potentially): Some DoH providers offer faster DNS resolution than traditional DNS servers.
• Censorship Resistance (Potentially): DoH can bypass some forms of internet censorship.

Methods for Enabling DoH in Windows 11

There are several ways to enable DoH in Windows 11. The best method depends on your comfort level with technical settings and your preferred DoH provider.

1. Using Your Router (Recommended)

Enabling DoH at your router level is generally the easiest and most effective method. This ensures all devices connected to your network use DoH, without requiring individual configuration. However, this requires your router to support DoH. Check your router's documentation or manufacturer's website to see if it's supported and how to enable it. Popular providers like Cloudflare, Google, and Quad9 offer detailed instructions on their websites for various router models.

2. Using Your Network Adapter Settings (Advanced)

This method allows more granular control and is suitable if your router doesn't support DoH or you want to use DoH only for specific networks. It involves configuring the DNS settings of your network adapter.

1. Open Settings (Win + I).
2. Go to Network & internet > Wi-Fi (or Ethernet).
3. Click on your active network.
4. Click on Change adapter options.
5. Right-click on your network adapter and select Properties.
6. Select Internet Protocol Version 4 (TCP/IPv4) or Internet Protocol Version 6 (TCP/IPv6), depending on your network configuration. Click Properties.
7. Select Use the following DNS server addresses.
8. This is where you would typically enter the DoH address, but Windows doesn't directly support DoH through this interface. We will use a workaround in the next section.

3. Using a Third-Party DNS Client (Recommended Alternative)

Many third-party DNS clients offer built-in DoH support. These clients usually provide a user-friendly interface to configure and manage your DNS settings, including selecting a DoH provider and troubleshooting issues. Popular options include:

• Cloudflare Warp: Offers a free and paid version with various features beyond DoH.
• NextDNS: Provides a customizable and powerful DNS solution with DoH support.
• AdGuard: A comprehensive ad blocker and privacy tool that includes DoH capabilities.

These applications typically have installers you can download and follow their guides for setup. They'll usually let you choose your preferred DoH provider directly within their interface.

Choosing a DoH Provider

Several reputable providers offer DoH, each with its own strengths and weaknesses. Popular choices include:

• Cloudflare (1.1.1.1): Known for its speed and privacy focus.
• Google Public DNS (8.8.8.8): A widely used and reliable option.
• Quad9 (9.9.9.9): Prioritizes security and blocking of malicious domains.

Research each provider's privacy policy and features before making a decision.

Troubleshooting

If you encounter problems after enabling DoH, try the following:

• Restart your computer: A simple restart often resolves minor issues.
• Check your network connection: Ensure you have a stable internet connection.
• Verify your DoH settings: Double-check that you entered the correct DNS server addresses.
• Check your firewall or antivirus software: They might be blocking DoH traffic. Temporarily disable them to test this possibility (remember to re-enable them afterward).
• Try a different DoH provider: Some providers may have temporary outages or compatibility problems.

Enabling DNS over HTTPS offers significant privacy and security benefits in Windows 11. Choosing the right method and provider will ensure a smooth transition to a more secure online experience. Remember that while DoH enhances privacy, it doesn't replace the need for a comprehensive security strategy, including using a VPN and strong passwords.
