Before a browser connects to a website, it usually looks up the site's domain name to find an address.
DNS over HTTPS (DoH) sends that lookup to a compatible DNS resolver over an encrypted HTTPS connection instead of a traditional unencrypted DNS request.
Quick example
At a public Wi-Fi hotspot, your browser looks up a website name. With DoH enabled, that DNS request travels encrypted to a compatible resolver instead of being sent as a traditional plain-text lookup.
Why it matters
DoH can hide the lookup from some observers on the local network. It does not make you anonymous: the DNS provider processes the query, and the website may still see your connection.
Do this next
Review your browser's DoH setting and the resolver it uses. Keep other privacy and security protections in place.
