Shodan InternetDB lookup for checking open ports, vulnerabilities, tags, and host data by IP.
The Network Entity Reputation Database IP search is a CESNET page that searches and lists IP addresses with hostname, ASN, country, events, reputation score, threat category, other properties, time added and last activity. It provides links to services including Shodan, Censys, AbuseIPDB, Talos Intelligence Center, Greynoise Visualizer and DShield. Results shown include DShield reports and OTX pulses.
CentralOps collection of DNS, WHOIS, traceroute, email, and network lookup tools.
Internet Census 2012 is a research paper describing a distributed port scanner built on insecure embedded devices with empty or default credentials. It scanned all IPv4 addresses and includes service probes for common ports, ICMP ping, reverse DNS and SYN scans. Data gathered during the research was released into the public domain.
Python OSINT crawler for extracting URLs, files, endpoints, and related website data.
LeakIX is a search and reporting platform with query syntax for ports, protocols, ASNs and IP ranges. It offers free and commercial plans, with paid tiers providing faster access to results, higher request limits, critical and RCE plugins, alert channels and downloadable results. Sponsorship supports voluntary researchers who dispatch free reports to companies and institutions.
Wappalyzer is a website technology checker that identifies the technologies a site is built with, including CMS and ecommerce platforms, analytics tools, frameworks and infrastructure services. It supports single-domain lookups or bulk analysis of thousands of sites, and can also be used in the browser, in a CRM, or through an API.
