DNS Lookup — A, AAAA, MX, NS, TXT, CNAME

Query common DNS record types for a domain. Results come from public DNS through our server-side resolver.

DNS lookup

🌐
Honest note: DNS queries are performed by our server using the system resolver (dig). The domain you enter is visible to that API. Private/reserved names are rejected.

Quick multi-type DNS lookup

Inspect A/AAAA (addresses), MX (mail), NS (nameservers), TXT (SPF and more), and CNAME in one place. For mail authentication specifics, use the dedicated SPF/DKIM/DMARC tools.

Frequently asked questions

Do you use Google DNS?

We use the server’s system resolver (dig), which follows the host’s configured resolvers.

Can I look up localhost?

No — local and private targets are blocked.

Propagation delay?

DNS TTL and caching may delay seeing recent changes.
