Look up a domain's A, AAAA, CNAME, MX, NS, TXT and SOA records in one go.
How to use the DNS lookup
- Enter a domain.
- Read the records by type.
- Compare with what your DNS provider shows after a change.
When to check DNS
After moving hosts, setting up email (MX, SPF and DKIM are TXT records), or verifying a domain for a service. Changes can take minutes to hours to show everywhere.
What each record type means
A points the name to an IPv4 address, shown with its TTL in seconds; AAAA does the same for IPv6. CNAME makes the name an alias of another hostname, common for www and hosted platforms. MX lists the mail servers, lowest priority number first. NS shows which provider answers DNS for the domain. TXT holds verification codes and email rules such as SPF. SOA names the primary nameserver and a serial that changes with each zone edit. CAA, if present, limits which certificate authorities may issue SSL certificates. "No records" for a type is normal; few domains use every type.
Problems a lookup reveals
The A record still shows the old host after a move: lower the TTL a day before the next change, then wait out the old TTL. No MX: the domain can't receive email. Two SPF TXT records: merge them, or SPF fails. A CAA record that doesn't include your certificate provider: renewals will fail. NS records at your registrar that don't match the DNS provider where you made the change, so the edits never go live. Results come from our resolver, so they can differ briefly from your own network.
