PUBLIC DNS

Look up common public DNS records.

Query A, AAAA, MX, TXT, NS, CNAME, and SOA for a domain from public resolvers.

What this lookup proves

Use this when you need a single public view of the records that affect websites and mail.

Public DNS is not your registrar panel. Private or split-horizon records will not appear. For a scored MailerZ readiness scan across MX, leftover routes, SPF, DKIM, and DMARC, use Troubleshooting.
