DNS Lookup
Look up the DNS records of a domain: A, AAAA, CNAME, MX, NS, TXT, SOA and CAA.
Enter a domain name to see its DNS records.
How to look up DNS records
- Type a domain name, such as example.com.
- Click Look up DNS.
- Read the records, grouped by type, with notes on where the website and email point.
What the record types mean
A and AAAA records hold the addresses of the server a domain leads to. CNAME makes one name an alias for another. MX records say which servers receive the domain's email, and TXT records hold text such as the SPF rule that says who may send email for it. NS records name the servers that hold all these records, SOA describes the zone, and CAA limits who may issue SSL certificates for the domain.
Frequently asked questions
I changed a record but still see the old value.
DNS answers are cached for the time shown in the "Refreshes every" column. After a change, the old value can linger for that long, sometimes up to 48 hours.
Why are there several A records?
Large sites spread visitors across several servers, so a name can have many addresses.
Can I look up a subdomain?
Yes. Type it in full, for example mail.example.com or _dmarc.example.com.
Is what I look up stored?
No. Our server makes the lookup once and sends the result back to you. What you enter and the result are not saved.
