A CLEARER VIEW OF YOUR NETWORK

DNS record lookup

Choose a domain and a record type to inspect the answer returned by Google Public DNS. This is a public resolver observation, not a scan of your device’s system DNS.

4 TOOLS

Run a focused DNS query

  1. Enter a hostname such as example.com. Test the root domain and www separately when investigating a migration.
  2. Select the record type related to your symptom, then run the diagnostic.
  3. Read DNS status and the answer list. Save the resolver and check time before comparing another result.

The domain and record type are sent to Google Public DNS only when you run the check.

Choose the right record type

TypeWhat to inspect
A / AAAAIPv4 / IPv6 addresses; check both after moving hosting.
CNAMEAn alias target, which may itself resolve elsewhere.
MXMail exchanger targets and preference values.
TXTPublished text such as verification or mail-policy entries.
NS / SOA / CAADelegation, zone information and certificate-authority policy.

Interpret missing records and errors carefully

A successful HTTP response is different from DNS status. Status 3 indicates NXDOMAIN; a successful DNS answer can also contain no record of the requested type. A timeout or blocked browser request does not prove the domain is absent.

TTL describes caching of an answer, not a countdown for every resolver worldwide. The AD field reports validation by the queried resolver; a false value alone does not establish that DNSSEC is broken.

Continue the investigation

Follow the hosting-change DNS checklist, or read the DNS record guide. Compare addresses with the IP lookup and test an IPv6 symptom using the IPv6 tool.

A little more visibility. A lot more confidence.

Transparent sources, useful diagnostics, and reports you can take with you.
