TXT record lookup
Read public TXT records for a domain.
Submitting sends this domain to Google Public DNS. No account or API key is needed.
Templates and calculations run locally in your browser. No generative AI or paid API is used. Review results before use.
Understand the DNS result
Each returned record includes a value and a time to live (TTL) in seconds. The result is what Google Public DNS returned at the time of your request, not a complete view of every resolver.
A practical example
Try a domain you administer in the txt record lookup. If you recently changed records, allow for existing cached records to expire before comparing results.
What this tool cannot tell you
TXT records can contain verification and email configuration data. Public records should never contain private secrets.
