Domain DNS Information

Get a one-page overview of a domain's DNS: where it points, which name servers host it, its mail servers, TXT records, certificate rules and DNSSEC status.

Tool status: Fully functional Runs entirely on this website or in your browser.

What this tool can and cannot do

Uses public DNS-over-HTTPS resolvers. Subdomains are not discovered automatically (DNS does not list them); query them individually.

Data sources: Public DNS-over-HTTPS resolvers

Understanding the results

A domain should have at least two NS records on different networks. CAA records are optional but recommended. DNSSEC "signed" means the resolver validated the answers.

Troubleshooting

Missing MX records mean the domain cannot receive email.
