Shodan Book

Shodan Update: February 2026

New

  • domain: search filter. Search for services by domain name, matched against reverse DNS (PTR) records and the domain names listed in certificates (SubjectAltNames).
  • Shodan Terminal spotlight. Search results now feature Shodan Terminal, our native desktop app.

Improved

  • Clearer organization management. Admins no longer also appear in the members list, so admins and members are easier to tell apart.
  • 2025 release notes and DNS DB docs. The Shodan book now has the 2025 release notes and updated guidance on the weekly Parquet exports of DNS data.

Data & Coverage

  • North Korean (DPRK) threat infrastructure. Shodan now collects HTTP on ports 1224, 1244 and 1249, which help track infrastructure used by North Korean threat groups.
