How to use DNS Lookup

  1. Enter Domain Name and adjust the options as needed.
  2. Run the tool and inspect its results, evidence and limitations.
  3. Copy or download the result, then verify it against the actual website, source data or business records.

Try a concrete example

Look up xunl.net MX records for receiving servers, or TXT for SPF declarations.

How to interpret results

This is one public recursive resolver observation. TTL is measured in seconds; cached answers do not establish worldwide propagation. NXDOMAIN is a DNS response, distinct from a timeout.

Frequently asked questions

Can emails still be sent without MX records?

MX specifies the receiving mail servers. Missing records do not mean email sending is impossible; checks should be combined with email provider configurations and A/AAAA fallback rules.

Why are the two test results different?

DNS changes, TTL caching, and resolver locations all affect results; please rely on authoritative records and service provider consoles as the final configuration basis.

Is NXDOMAIN a tool error?

NXDOMAIN is a non-existent domain status returned by the DNS resolver, which is different from network timeouts or upstream unavailability.

DNS lookup practical guide and common questions

What does a DNS lookup do?

DNS maps domain names to addresses and service records. Different record types help separate website connection problems from email configuration problems.

Who is this for, and when is it useful?

Site and email administrators troubleshooting a record change or connection problem.

How do I use this DNS lookup?

Enter a domain and record type, compare returned values with your intended configuration, or use the combined website audit for related checks.

How should I interpret the results?

Compare record type, value, TTL and resolver status. NXDOMAIN, an empty answer and a resolver timeout mean different things; check authoritative settings and cache timing after changes.

Where is the work performed, and which services receive data?

The domain and record type are submitted to our backend for public DNS resolver queries. Authoritative records are not changed and no domain dashboard is accessed.
