Check a domain's public records

The Domain Name System (DNS) tells internet services where to find a domain's website, email, and other published information. Enter a domain to look up its public records. No signup required.

Look up public records

What the results mean

A and AAAA: addresses used to reach a host over the internet.
CNAME: an alias pointing one name to another.
MX, or Mail Exchange: servers that receive email for the domain.
NS, or Name Server: the services responsible for answering the domain's DNS queries.
TXT, or text records: published text used for verification and other settings.
SPF, or Sender Policy Framework: identifies permitted sources of email for a domain.
DKIM, or DomainKeys Identified Mail: publishes information used to check a message's digital signature. Lookup depends on knowing the relevant selector.
DMARC, or Domain based Message Authentication, Reporting, and Conformance: publishes how a domain asks receivers to handle authentication failures and send reports.

A starting point, not a verdict

This tool reads public records. It does not sign in to your systems, run a vulnerability scan, or establish that your email is secure. A missing result may need a closer look at the domain, record name, or provider setup.
