Advanced IP Intelligence & Cyber-Reconnaissance Platform. Reveal the invisible with precision data.
WhoisNexus provides a comprehensive suite of network analysis tools. Unlike standard Whois lookups, we correlate IP data with global threat intelligence, providing context on whether an IP is malicious, a known scanner, or part of a botnet.
Classless Inter-Domain Routing (CIDR) is a method for allocating IP addresses and IP routing. A /8 block contains over 16 million addresses, while a /24 contains 256. Navigate our database to explore these subnets heirarchically.

Instantly verify if an IP is involved in DDoS, spam, or hacking attempts using our community database.
Easily browse the entire IPv4 space. Our drill-down structure (/8, /16, /24) allows intuitive network exploration.
Get official registration info (ASN, ISP, Location) and PTR records in real-time.
Understanding the threats detected by our systems.
An automated attack where a script attempts to guess the password of a Secure Shell (SSH) server by trying thousands of combinations. This is a common method used by botnets to gain unauthorized access to servers.
The practice of sending packets to specific ports on a host to identify open services. While used by administrators for auditing, it is often the first step in an attack to find vulnerabilities.
A network of compromised computers (bots) controlled by a third party. They are often used to coordinate DDoS attacks, send spam, or perform distributed brute-force attacks.
