DNS over HTTPS (DoH) is a privacy-enhancing protocol that encrypts your DNS queries, preventing your internet service provider (ISP) and other potential eavesdroppers from seeing which websites you visit. This guide will walk you through enabling DoH on various devices and operating systems.
Traditionally, DNS queries are sent in plain text, making them vulnerable to interception. DoH solves this by encrypting these queries using HTTPS, the same protocol used for secure web browsing. This means your DNS requests are shielded from prying eyes, improving your online privacy and security. By encrypting your DNS lookups, DoH protects against DNS spoofing and other attacks that can redirect you to malicious websites.
While DoH offers significant advantages, it's crucial to be aware of potential drawbacks:
Many modern operating systems now offer built-in support for DoH. Check your network settings for options to specify a custom DNS server using DoH. For example, some versions of Windows and macOS and many Linux distributions offer this functionality.
Several major web browsers, including Chrome, Firefox, and Edge, allow you to configure DoH directly within their settings. This usually involves selecting a DoH provider from a list or entering a custom DoH URL. Look for options related to "Privacy" or "Network" in your browser's settings.
Example (Chrome): While the exact steps may vary slightly based on your Chrome version, you might find DoH settings within the "Privacy and security" section, potentially under "Security" or a similar option. Look for settings that allow you to specify a custom DNS server. Popular DoH providers include Google Public DNS over HTTPS (https://dns.google/dns-query) and Cloudflare DNS over HTTPS (https://cloudflare-dns.com/dns-query).
For more advanced control, you can use a dedicated DNS client application. These applications often offer features beyond basic DoH support, such as advanced privacy options and logging capabilities. Examples include OpenDNS and Cloudflare DNS clients (which may or may not offer DoH depending on the version and platform).
Some modern routers allow you to configure DoH at the router level. This will enable DoH for all devices on your network. Consult your router's manual for instructions on how to do this. Note that router support for DoH varies greatly among manufacturers and models.
Selecting a reputable DoH provider is crucial for privacy. Consider the provider's privacy policy, its location, and its security practices. Research different providers and choose one that aligns with your needs and priorities.
Always choose a well-established and reputable DoH provider. Using an unknown or untrusted provider could expose you to security risks. Verify the provider's authenticity and examine their privacy policies before relying on their services.
By following these steps, you can effectively enhance your online privacy and security by enabling DNS over HTTPS.
