DNS over HTTPS (DoH) is a privacy-enhancing technique 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 setting up DoH on various devices and platforms.
Normally, when you type a website address into your browser, your computer sends an unencrypted query to your DNS server to resolve the domain name (e.g., google.com) into an IP address. DoH changes this by sending your DNS query over HTTPS, the same secure protocol used for online banking and other sensitive transactions. This encryption prevents anyone intercepting your traffic from seeing your browsing history.
The method for setting up DoH varies depending on your operating system and browser. Below are instructions for some popular options:
Many modern browsers now support DoH natively. You can usually configure it in your browser's settings. Look for options related to "DNS", "Privacy", or "Network". Popular providers include Cloudflare (1.1.1.1), Google Public DNS (8.8.8.8), and Quad9 (9.9.9.9). Consult your browser's documentation for specific instructions.
Windows 10 and 11 offer limited native DoH support. You might need to use third-party DNS clients or configure your network adapter settings. More advanced options involve modifying your registry – proceed with caution!
macOS doesn't natively support DoH. You'll likely need to use a third-party DNS client or configure your network settings manually. Consider using tools like the terminal or network utility for advanced configuration.
Linux distributions offer flexible DoH setup options. You can often configure DoH by editing your network configuration files (e.g., `/etc/resolv.conf`) or using your distribution's network management tools. Systemd-resolved often handles this on modern systems. Consult your distribution's documentation for specific details.
On Android and iOS, you can usually change your device's DNS settings directly in the network configuration. Look for options in your Wi-Fi or cellular settings to specify a custom DNS server address.
Several third-party DNS clients offer easy DoH configuration. These clients often provide additional features and advanced settings. Popular options include [link to a reputable DNS client] and [link to another reputable DNS client]. Research different clients to find one that suits your needs.
Selecting a DoH provider is crucial. Consider factors like privacy policy, security practices, speed, and location of the server. Research providers carefully and choose one that aligns with your priorities.
While DoH offers significant advantages, it's not without potential downsides. Some ISPs might block or throttle DoH traffic. Furthermore, the privacy benefits depend on the trustworthiness of the DoH provider you choose. Always research providers thoroughly and select one with a strong privacy policy.
Implementing DoH is a simple yet effective way to enhance your online privacy and security. By following the instructions provided in this guide, you can take control of your DNS traffic and enjoy a more secure browsing experience.
