Features Included in this Toolkit
RDAP & WHOIS
Utilizes a Multi-API Fallback System prioritizing the modern RDAP protocol over legacy WHOIS to bypass strict CORS and rate limits, returning accurate registration dates, registrars, and statuses.
Comprehensive DNS
Instantly fetch and map all exposed DNS zones for a given domain, including IPv4 (A), IPv6 (AAAA), Mail Exchangers (MX), Nameservers (NS), and Verification Texts (TXT).
HTTP Headers Check
Reveals the backend web server technologies (Nginx, Apache, Cloudflare), caching rules, and security policies (HSTS, CSP) being transmitted via HTTP responses.
IP Geolocation
Resolves the target domain to its primary IP address and performs a geographical lookup to determine its physical hosting location, ISP, and ASN.
SSL/TLS Certificate Decoding
Scans the target server securely to retrieve live SSL certificate data. Verify issuers, valid-from and valid-to expiration dates, security algorithms, and Subject Alternative Names (SANs).
