About DNS Lookup

Use a hostname lookup to compare public DNS answers with the values you expected after a configuration change.

The report groups A, AAAA, MX, TXT, NS and CNAME answers.

Each group lists the number of returned entries.

1
Enter a hostname
Use a public domain such as example.com.
2
Run Lookup DNS
Wait for the server resolver.
3
Inspect the record groups
Compare each record type with the expected configuration.

Public hostname → grouped DNS answers

Enter example.com and inspect the A and AAAA groups without assuming either has a fixed answer.
