1. 01Enter a domain and pick at least one of A, AAAA, CNAME, MX, NS, TXT, SOA or CAA.
2. 02Run the query; the page shows the records and TTLs returned for each type.
3. 03Up to 10 recent domains are kept locally in the browser.

• Each type is a separate request with a timeout of about 8 seconds; more types means more requests.
• The fallback happens when a request throws; it does not mean two resolvers merge their answers at the same time.
• A public recursive resolver sees the domain and record type you asked for; results are also affected by DNS caching, TTLs, geography and DNSSEC.
• This is a resolution lookup: it does not scan ports on the target host and does not change any DNS configuration.

• Good for troubleshooting name resolution, mail MX records, authoritative NS records and TXT verification records.
• Comparing the public DNS data a domain currently publishes.

The queried domain and the record types you choose are sent to Google Public DNS, and to Cloudflare when the fallback fires. Recent domains are written to local localStorage. Do not use it to probe internal namespaces you are not entitled to query, or to disclose sensitive internal host names.
