DNS Record Lookup

Look up DNS A, AAAA, MX, TXT, CNAME, NS, and DNSSEC records instantly using Google's public resolver.

How to use this tool

Enter a domain, hostname, or IP address and choose the record type to query.
Optionally enable DNSSEC flags (DO and CD), then run the lookup against the selected resolver.
Review answer, authority, and additional sections, then copy or export JSON/CSV diagnostics.

What you can inspect

Record payloads with TTL values across answer, authority, and additional sections.
Resolver status codes to quickly identify NXDOMAIN, SERVFAIL, and related responses.
Raw JSON response data for deeper debugging and machine-readable exports.

Operational use

Validate DNS changes during migrations and rollout windows.
Compare resolver outcomes when debugging routing and delivery problems.
Capture sharable DNS evidence for incident tickets and change reviews.

FAQ

Which resolver is used?: You can query Google DNS or Cloudflare DNS directly from the resolver selector in the tool.
Can I run reverse DNS lookups?: Yes. PTR mode accepts IPv4, IPv6, or prepared in-addr.arpa/ip6.arpa names and formats them for lookup.
Can I export results?: Yes. You can copy a JSON report or download JSON and CSV exports from the results section.
