DNS lookup

Look up common DNS records for a domain, including A, AAAA, MX, TXT, NS, and canonical-name data.

What this tool does

DNS lookup queries the public resolver path for a domain and displays common record types. A and AAAA records point to IP addresses, MX records route mail, TXT records often contain verification and security policy data, and NS records list authoritative nameservers.

DNS answers can vary by resolver, location, TTL, DNSSEC state, and provider routing. Use the result as a quick diagnostic view, not as the only source of truth for a production DNS change.
