What this tool does

It resolves a domain’s DNS records live, in your browser, over DNS-over-HTTPS, and groups them by type so they’re readable. Use it to confirm a record you just added, debug why a name won’t resolve, or inspect how any domain is configured:

  • A / AAAA, the IPv4 / IPv6 addresses a name points to.
  • CNAME, aliases to another name. NS, the authoritative nameservers.
  • MX, mail servers. TXT, where SPF, DKIM, DMARC, and verification records live.
  • SOA, zone metadata. CAA, which certificate authorities may issue certs.

New to any of this? Start with what DNS is. Checking email setup specifically? The deliverability checker scores SPF/DKIM/DMARC and tells you what to fix.
