About this tool
CNAME Lookup runs in your browser with no backend of its own. Enter a domain and pick a record type; CNAME Lookup fetches the answers live over DNS-over-HTTPS.
CNAME Lookup shows exactly what the public resolver returns for the record type you choose. The DNS query is sent from your browser to a public DNS-over-HTTPS resolver; this site has no backend and never sees it. A network connection is required, so it does not work offline.
