Look up a domain’s DNS records to check a website move, email setup or verification record.

Record types
| Record | What it does |
|---|---|
| A / AAAA | Points the domain to a server’s IPv4 or IPv6 address |
| CNAME | Makes a name an alias of another name |
| MX | Lists the mail servers that receive email |
| NS | Lists the nameservers that answer for the domain |
| TXT | Holds text, such as SPF, DMARC and site verification codes |
| SOA | Key settings for the domain’s DNS zone |
| CAA | Lists which certificate authorities may issue SSL certificates |
Changed a record but see the old one?
DNS answers are cached for the time-to-live (TTL) shown. Wait for that time to pass, and check that you edited the records at the nameservers listed under NS.
How the check works
Your browser sends the address to our server, which makes the request and sends back the result. We don’t keep the addresses you check. To stop misuse, each visitor can run about 20 checks a minute.
Frequently asked questions
Why is CNAME empty?
A domain’s root normally can’t have a CNAME. Try the www name instead.
Can I check a subdomain?
Yes, such as mail.example.com.
Which resolver do you use?
Our server’s normal DNS resolver.
