Read DNS answers, TTLs and negative responses

How to use the workspace

1. Enter a public DNS name. For reverse lookups, choose PTR and provide an appropriate IP or reverse name.
2. Select one or more of A, AAAA, MX, CNAME, NS, TXT, SOA and PTR.
3. Submit the query explicitly. Review each record type independently, including its TTL and response state.

A concrete starting point

Name: example.com
Types: A, AAAA, MX
TTL is shown in seconds for every returned record.

The example only fills an input. Real records are retrieved when you submit and may differ over time.

Read the result carefully

NXDOMAIN means the queried name does not exist according to the resolver. NODATA means there is no answer for that record type. Neither should be mistaken for a timeout. MX preferences are priorities, not delivery-speed measurements; smaller values are generally preferred.

Common mistakes to avoid

• A cached answer can differ from an authoritative server or another region.
• TXT records can consist of multiple chunks; the readable value joins those chunks.
• A CNAME or missing AAAA record alone does not establish service availability.

Limits & privacy

Eight supported record types, bounded query budgets and an 8-second API deadline. Targets are sent to the diagnostics API and resolver. Partial reports retain their stopping reason.
