DNS Lookup
Look up A, AAAA, CNAME, MX, TXT, NS, SOA, and CAA records for any domain over DNS-over-HTTPS, straight from the browser. Shows the TTL on each record and reads the answer back from Cloudflare's resolver, so it is a real lookup rather than a cached guess.
Method & assumptions
- Each record type is a separate query fired in parallel against Cloudflare's 1.1.1.1 resolver over DNS-over-HTTPS.
- TTL is the seconds the resolver says the record may be cached — not how long ago it changed.
- An empty result for a type means the domain exists but publishes no record of that type; NXDOMAIN means the domain itself is not registered.
- This is a live lookup, not a cache of ours, so results reflect what the resolver sees right now.
- This tool sends the domain you enter to Cloudflare's public resolver to make the lookup. Nothing is sent to JCIT, and the tool itself runs entirely in your browser.
