Find DNS Host Records (Subdomains)

Best-effort discovery from public sources. Results can be incomplete.

How This Query Works

Subdomain discovery aggregates passive public feeds, normalizes hostnames, and removes duplicates under the target root zone.

  • 1Input should be one root domain (for example example.com).
  • 2Only in-scope hosts ending with the target root are retained after normalization.
  • 3Source labels indicate where each hostname was observed, useful for confidence scoring.
  • 4Use JSON/CSV export for inventory baseline, drift checks, and external enrichment.
