DoH Provider Checker
DNS over HTTPS (DoH) encrypts your DNS lookups inside a normal HTTPS connection, so nobody on the network can read or modify the sites you look up. This tool tests the four most popular public DoH providers live from your browser, measures each one's latency, and ranks them fastest first.

How to use
- Keep the default test domain or type your own.
- Click Run check to query all four providers at once.
- Read the table: reachable providers are sorted fastest first; blocked ones are marked clearly.
Note: Some office, school, and mobile networks block DNS over HTTPS on purpose. If one or more providers fail here, that usually means your network is restricting encrypted DNS — try the same check from a different network to compare. Nothing is stored; the queried domain is visible to the providers you test.
