DNS Record Lookup
Inspect A, AAAA, MX, NS, TXT, SOA, and CAA records with redundancy and misconfiguration analysis.
Best for site owners, IT teams, and agencies validating DNS after migrations, registrar changes, mail provider switches, or new subdomain launches.
What This Tool Checks
- Full record inventory in one pass
- Name server redundancy checks
- SPF, DMARC, and CAA presence signals
Why It Matters
DNS is the routing layer everything else depends on. Missing address records, single name servers, duplicate SPF entries, and absent CAA policy all create availability or spoofing risk that stays invisible until something breaks.
Best For
Best for site owners, IT teams, and agencies validating DNS after migrations, registrar changes, mail provider switches, or new subdomain launches.
What To Do Next
Use the record inventory to fix redundancy and mail-authentication gaps first, then re-run the lookup to confirm the zone matches what you intended to publish.

What does the DNS Record Lookup look for?
DNS Record Lookup focuses on full record inventory in one pass, name server redundancy checks, spf, dmarc, and caa presence signals. It is designed to help teams identify this category of weakness quickly and then move into broader workflows if deeper follow-up is needed.
What is the difference between Quick and Comprehensive mode?
Quick mode stays public for focused diagnostics. Comprehensive mode is intended for authenticated workflows where users need saved history, richer follow-up, and broader account-linked execution.
When should I use the full Vulnify platform instead?
Use the full platform when you need more than one focused diagnostic, want to keep reports and history, or need scheduled scans, exports, and broader vulnerability coverage beyond dns record lookup.
