Host Discovery with Nmap

Nmap (Network Mapper) is a powerful tool for network discovery and security auditing. One of its primary uses is to discover live hosts on a network.

Basic Ping Scan:

nmap -sn 192.168.1.0/24

• -sn: Ping Scan - disables port scan. Nmap will only try to determine if hosts are online.

This is often the first step in active reconnaissance to map out the target network.
