Nmap "Network Mapper" is a utility for network exploration, administration, and security auditing. It uses IP packets in novel ways to determine which hosts are available online using host discovery, which TCP/UDP ports are open using port scanning, and what applications and services are listening on each port using version detection. It can also identify remote host OS and device types via TCP/IP fingerprinting. Nmap offers flexible target and port specifications, decoy/stealth scanning for firewall and IDS evasion, and highly optimized timing algorithms for fast scanning.
