-**Nmap** (**N**etwork **Map**per) is a cross-platform command-line //port scanner//. It identifies which ports are open on a networked computer, which in turn can help identify what services are running on that computer. This is useful to both sysadmins and hackers alike for discovering potential points of attack in prospective targets. Its ability to scan entire networks is very useful when combined with [[tools:whois|WHOIS]] information about organizations you may be targeting.+**Nmap** (**N**etwork **Map**per) is a cross-platform command-line //port scanner//.

 +**Note:** Port scanning is a fast way to get your IP address flagged by some hosts. For best results, pair this with a [[security:vpn|VPN]] and use a [[diy:change-mac|randomized MAC address]].
