DNS Lookup — A / MX / TXT / CNAME Records
Resolve A, AAAA, MX, TXT, NS, and CNAME records against authoritative servers — useful for verifying mail and hosting setups.
How to use
Resolve a domain's A, AAAA, MX, TXT, NS, and CNAME records — useful for site owners verifying DNS, mail, or hosting setups.
- Enter the domain (e.g. example.com — no http:// or https://).
- Choose a record type, or query all of them.
- Read the name, record type, TTL, and value columns.
- If the response looks unchanged, check the TTL — your previous query may still be cached.
TXT records hold SPF, DKIM, and DMARC entries that are critical for email deliverability. Long CNAME chains may exceed the response size limit and be partially truncated.
