The Nmap Project released Nmap Security Scanner version 6.00. It is the product of almost three years of work, 3,924 code commits, and more than a dozen point releases since the big Nmap 5 release in July 2009.
Nmap 6 includes a more powerful Nmap Scripting Engine, 289 new scripts, better web scanning, full IPv6 support, the Nping packet prober, faster scans, and much more! We recommend that all current users upgrade.
Nmap (“Network Mapper”) is a free and open source (license) utility for network discovery and security auditing. Many systems and network administrators also find it useful for network inventory, managing service upgrade schedules, monitoring host or service uptime, and many other tasks
