DNS inspector

Live lookups over DNS-over-HTTPS — A, AAAA, CNAME, MX, TXT and NS records resolved against public resolvers, entirely from your browser. Nothing is proxied or stored.

How this works

Queries go straight from your browser to the resolver's public DNS-over-HTTPS endpoint using the application/dns-json wire format — the same records any resolver on the internet would return. There is no server component, no logging, and no privileged access: it's a demonstration of doing real network tooling entirely client-side. Comparing resolvers is a quick way to spot DNS propagation lag after a record change.
