Passive domain reconnaissance using Python stdlib collects subdomain data, TLS information, WHOIS records, and DNS data without external APIs. It runs via a CLI script that outputs JSON, requiring no third-party dependencies.

Yes, subdomain discovery and SSL certificate inspection are performed using Python stdlib. Subdomains are found via Certificate Transparency logs, and SSL checks extract expiry, SANs, and issuer data without external packages.

DNS records including A, AAAA, MX, NS, TXT, and CNAME are resolved using the Python stdlib. The script supports bulk analysis across multiple domains, outputting the resolved DNS data as structured JSON.

Passive OSINT domain intelligence works across Linux, macOS, and Windows. Because it relies entirely on the Python standard library, it functions consistently across these operating systems without requiring platform-specific dependencies.

Domain availability assessment is conducted using passive signals gathered through the Python stdlib. By analyzing DNS records and WHOIS registrar data, the script determines availability without sending active probing requests to the target.

No external API keys are needed for WHOIS lookups or domain intelligence gathering. The implementation uses Python stdlib to retrieve registrar data and perform all passive reconnaissance tasks independently.
