Look up A, AAAA, CNAME, MX, TXT and NS records for any domain in one call — via Cloudflare's DNS-over-HTTPS resolver. Free, live, no signup.
Live DNS query — nothing storedFrequently asked questions
Which DNS record types does this check?
A, AAAA, CNAME, MX, TXT and NS by default, all in a single call. You can also narrow to just one type using the type parameter.
Where does the data come from?
Cloudflare's public DNS-over-HTTPS resolver -- the same infrastructure that powers 1.1.1.1, queried live for every request.
Why check DNS records manually instead of just visiting the site?
DNS records reveal infrastructure a browser hides: which mail servers handle a domain's email (MX), what SPF/verification TXT records are published, and which nameservers actually control the domain -- useful for verifying a domain before trusting it, debugging email delivery, or auditing your own infrastructure.
Can I use this in my own code?
Yes. This page calls the same free, public API endpoint you can call directly: GET /api/dns-lookup?domain=example.com. No signup or API key required.
