DNS Lookup
Looks up the DNS records published for a domain. Enter a domain on its own, as "example.com", to see its A, AAAA, MX, TXT, and NS records.
Looks up the DNS records published for a domain. Enter a domain on its own, as "example.com", to see its A, AAAA, MX, TXT, and NS records.
To ask for particular types, list them after the domain, as "example.com MX TXT". Supported types are A, AAAA, MX, TXT, NS, CNAME, SOA, and CAA.
Every type is queried at the same time, so asking for several is no slower than asking for one. Each answer includes its TTL — how long resolvers are told to cache it.
Use cases
- Checking that a mail provider's MX records are in place
- Confirming a domain verification TXT record has been published
FAQ
Is my data sent to a server?
Yes — the lookup runs on the server, which queries DNS for you.
Why does a record type come back empty?
Because the domain publishes nothing of that type. That is a normal answer rather than an error — a domain with no mail, for instance, has no MX records.
What is the TTL?
The time to live, in seconds. It is how long resolvers are told they may cache the answer before asking again.
Why might my recent DNS change not show here?
Resolvers cache answers for the length of the TTL, so a change can take that long to become visible everywhere.
