DNS Lookup
Look up the A, AAAA, CNAME, MX, NS, TXT, SOA, SRV and CAA records of any domain with their TTLs in one query.
Look up DNS records
Queried live from our server, so you see what the rest of the internet sees.
What the DNS Lookup does
DNS Lookup asks the public DNS for a domain's records and prints every answer with its time to live. Pick one record type to see just that answer, or choose "All" and the tool walks through A, AAAA, CNAME, MX, NS, TXT, SOA, SRV and CAA in one go, grouped by type so a long TXT list does not hide the mail servers.
The lookup runs from our server, not your browser, so you see the records the rest of the internet sees rather than a cached copy on your laptop or office resolver. That matters right after a change: if the new A record shows here, the migration is propagating; if the old one still shows, read the TTL to know how long caches may hold it.
Each record shows exactly as the zone publishes it. MX and SRV rows are sorted by priority, SOA shows the serial, refresh, retry, expire and minimum TTL fields, and CAA shows the flag and tag so you can confirm which certificate authorities a domain allows.
Step by step
- 01Type the domain, with or without www. A full URL is fine; the host name is taken from it.
- 02Choose a record type, or leave "All" to query the nine common types at once.
- 03Press Look up. Results come back grouped by type, each row with its TTL in seconds.
- 04Compare the records with what you expect: the A record with your host's IP, MX with your mail provider, TXT with SPF and verification strings.
Common questions
A name can have a CNAME or other records, never both. If www is a CNAME to your platform, you will see it under CNAME; if it has its own A record, there is no CNAME to show. When a type comes back empty for the whole domain it is simply left out of the grouped result.
Time to live, in seconds: how long a resolver may cache the answer before asking again. A 300 second TTL means a change is visible everywhere within about five minutes; 86400 means up to a day. Lower the TTL a day before a planned migration and raise it again afterwards.
Both can be right at the same time. Your machine and your ISP cache older answers until their TTL runs out. This tool queries from our server, which usually reflects the authoritative zone sooner. If they still differ after the TTL has passed, check that every name server for the domain serves the same zone.
Any public name works, including deep subdomains like mail.eu.example.com. Names that only exist on a private network cannot be resolved from the public internet and will come back empty.
