DNS record lookup

Query any domain's DNS records, from A and MX to TXT, CAA, and SRV, to debug mail, hosting, and captive-portal problems.

Look up DNS records for a domain

Results are read-only DNS resolutions. For TXT, check SPF, DKIM, and DMARC policies; for MX, lower priority numbers are tried first.

DNS is where most outages start

DNS maps names to addresses and routes mail, so a single wrong record can take a site or mailbox offline. This tool resolves the record types network teams check most often, so you can confirm what the internet actually sees for a domain right now.

What this tool gives you

  • A, AAAA, MX, TXT, NS, CNAME, SOA, CAA, SRV, and PTR records on demand.
  • TXT output you can scan for SPF, DKIM, and DMARC policies that control email deliverability.
  • Read-only lookups. The tool resolves records and never connects to the target host.
