DNS A / AAAA lookup
Look up public IPv4 and IPv6 records using Google Public DNS.
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 dns a / aaaa lookup. If you recently changed records, allow for existing cached records to expire before comparing results.
What this tool cannot tell you
DNS records can be cached and may vary by resolver or location. Results are a point-in-time public lookup.
