DNS Lookup Tool

Look up A, AAAA, CNAME, MX, TXT, NS, SOA and CAA records for any domain name.

Queries go directly from your browser to Cloudflare DNS (1.1.1.1) over DNS-over-HTTPS.

This tool runs entirely in your browser — your data never leaves your device.

What is DNS Lookup Tool?

DNS is the system that translates memorable domain names into the IP addresses machines actually connect to. Each domain carries several record types serving different purposes: A points at a web server, MX names the mail servers, TXT holds verification strings like SPF and DKIM, and NS identifies which provider runs the domain's DNS.

This tool queries Cloudflare's 1.1.1.1 resolver directly from your browser over DNS-over-HTTPS. Our server plays no part in it — which means you get genuine results from the public DNS system, and nobody here logs what you looked up.

How to use

  • Enter a domain, for example example.com. No need to type http:// — it is stripped automatically.
  • Pick the record type you want; A is the default.
  • Click Look up. Results include the TTL, showing how long the record stays cached.
  • Switch record types to re-query instantly without retyping the domain.

Frequently asked questions

Why does a lookup still return the old value after I changed my DNS?

Because of TTL. Every record has a lifetime, and intermediate resolvers hold the old answer until it expires. The TTL column shows how long is left. DNS changes typically take anywhere from a few minutes to 48 hours to propagate fully.

What are TXT records used for?

Mostly domain ownership verification and email configuration. SPF declares which servers may send mail as your domain, DKIM holds the public key used to sign messages, and DMARC states what to do with mail that fails those checks.

What does a CAA record do?

It specifies which certificate authorities are allowed to issue SSL certificates for your domain. If someone tries to obtain a certificate from an authority not on the list, the request is refused.
