DNS over HTTPS (DoH) is a privacy-enhancing technology that encrypts your DNS queries, preventing your internet service provider (ISP) and potential eavesdroppers from seeing which websites you visit. While Windows 11 doesn't natively support DoH in the same way as some browsers, you can configure it through your network settings or by using a third-party DNS provider like Cloudflare or Google Public DNS. This article will explore the benefits and drawbacks of using DoH on Windows 11, helping you make an informed decision.
The Domain Name System (DNS) translates human-readable domain names (like google.com) into machine-readable IP addresses. Traditionally, DNS queries are sent in plain text, making them vulnerable to interception. DoH encrypts these queries using HTTPS, the same protocol used for secure web browsing. This added encryption prevents third parties from observing your online activity, enhancing your privacy.
Enhanced Privacy: The most significant advantage is improved privacy. Your ISP and others cannot see the websites you visit.
Increased Security: Encryption protects against DNS spoofing and other attacks that can redirect you to malicious websites.
Improved Performance (Potentially): Some DoH providers offer optimized DNS servers that can improve the speed of website loading.
Censorship Circumvention (Potentially): In some regions with internet censorship, DoH can help bypass restrictions by encrypting your DNS requests.
Potential for Compatibility Issues: While generally well-supported, some older or less-maintained applications might encounter problems with DoH.
Reduced Control for Network Administrators: In corporate or managed environments, DoH can complicate network management and security policies.
Dependence on a Third-Party Provider: Your privacy relies on the security and trustworthiness of the chosen DoH provider. Choosing a reputable provider is crucial.
Potential for Tracking (Depending on Provider): While DoH protects against ISP tracking, some providers may log your DNS queries. Carefully review the privacy policies of any DoH provider you consider.
No Native Windows Support (Limitations): Windows 11's built-in DoH implementation is limited compared to the more robust support found in some browsers. This might mean less granular control over settings.
There are several ways to enable DoH on Windows 11. The most common is to change your DNS settings to a DoH-enabled provider. You can do this through your network adapter settings, usually found in the Control Panel or Settings app. Look for the option to manually set the DNS server address. Popular DoH providers include:
1.1.1.1 (IPv4) or 2606:4700:4700::1111 (IPv6)8.8.8.8 (IPv4) or 2001:4860:4860::8888 (IPv6)9.9.9.9 (IPv4) or 142.142.142.142 (IPv6)Note: Many routers now also support DoH. Configuring your router might provide a more convenient solution, applying DoH to all devices on your network. Always check your router's documentation for instructions.
The decision of whether to enable DoH on Windows 11 depends on your priorities. If privacy and security are your main concerns, enabling DoH with a reputable provider is a good choice. However, be aware of potential compatibility issues and the need to choose a trustworthy provider with a clear privacy policy. Carefully weigh the pros and cons based on your specific needs and tech savviness before making a change.
