That address reaches the resolver over plain, unencrypted DNS, which is all a bare IP address can describe. Encrypted DNS requires more: a hostname to check the certificate against, a port, and a protocol. None of that fits in the settings box, and none of it can be worked out from the address already sitting there.</p> https://blog.dundns.eu/posts/doh-dot-doq-odoh-explained/ Sun, 26 Jul 2026 09:30:00 +0000 https://blog.dundns.eu/posts/doh-dot-doq-odoh-explained/ <p>Every time you open a website, your device first asks a DNS resolver where to find it. Without encryption that question travels in the clear, readable by your internet provider, by the café Wi-Fi, and by everyone else handling the traffic along the way. Taken together, those questions are a running list of every site you visit.</p>
