Infrastructure & Network Reconnaissance
OSINT.SH
All-in-one web toolkit: DNS history, reverse IP, WHOIS.
OSINT.SH provides a web-based interface for gathering infrastructure intelligence through DNS history lookups, reverse IP address queries, and WHOIS data retrieval. This toolkit assists researchers in mapping network assets and identifying historical domain configurations to support legitimate cybersecurity investigations and threat analysis.
Dual-use tool. This is capable of legitimate research (journalism, security, due diligence) and of harassment or stalking. Listing it here is not an endorsement of either use.
