Free online DNS lookup
Enter a domain to see all its main DNS records: where the website points (A/AAAA), who receives its mail (MX), which name servers are responsible (NS) and service TXT records.
Which DNS records the lookup shows
The lookup asks DNS for the main record types of a name in one go: A and AAAA (the IPv4 and IPv6 addresses the site points to), CNAME (aliases), MX (mail servers), NS (the name servers responsible for the domain), TXT (SPF, DMARC and verification codes), SOA (zone details) and CAA (which certificate authorities may issue SSL for it).
It is the quickest way to see where a domain actually points right now: after a hosting move, after changing nameservers or when something has stopped working. Enter the exact name you need, because example.com, www.example.com and mail.example.com each have their own records.
How to read DNS records
- A and AAAA: the IP address visitors connect to. It must match the address your hosting panel shows for the site.
- NS: who controls the zone. Records you edit at a provider that is not listed here have no effect.
- MX: where mail for the domain is delivered. No MX means the domain cannot receive email.
- TXT: a domain must have exactly one SPF record (v=spf1). The DMARC record lives on a separate name; the email check finds it for you.
- CAA: if present, only the listed authorities may issue certificates; if there is none, any authority may.
- No DNS records found: the domain does not exist, has expired, or its nameservers do not answer.

Frequently asked questions
- Why does the check still show old records after I changed them?
- DNS answers are cached for the record's TTL, often one to four hours, and a nameserver change can take up to 48 hours to spread. The lookup goes through our server's resolver, which caches like any other, so it shows what a typical visitor sees at the moment.
- Can I check a subdomain?
- Yes, enter it in full, for example shop.example.com. Every name has its own set of records.
- Does the lookup show every record in the zone?
- No. DNS does not allow listing a whole zone, so the tool asks for the common record types of the exact name you entered. Records on other names, such as DKIM keys, have to be requested by their own name.
