DNS Lookup

Inspect the DNS records behind a domain.

Live lookup

A DNS lookup asks a resolver which records a domain publishes and returns their values and TTLs. The A record holds the IPv4 address, AAAA the IPv6 address, MX the mail servers, and TXT the verification and policy strings.

How DNS Lookup works

What it does

Inspect the DNS records behind a domain.

What you get

Record types, returned values and their cache lifetimes (TTL).

Live data sources

The target is sent to a network provider. Results include their source; timeouts and unavailable data are clearly marked.

What if a check cannot finish?

Confirm your input and try again. A timeout, blocked request, or unavailable provider is not proof that a domain is broken. Internet measurements and third-party services have limits.

DNS Lookup — frequently asked questions

What is a TTL?

Time to live, in seconds — how long a resolver may cache the record before asking again. A TTL of 3600 means caches can hold the answer for an hour.

Why does this show a different IP than ping does?

Your computer may be using a cached answer or a different resolver. This lookup queries a public resolver directly, so it can see a newer value than your device has.

What does an empty result mean?

The domain publishes no record of that type. That is normal — most domains have no SRV or CAA record, for example.
