Angry IP Scanner is a small open source Java application which performs host discovery ("ping scan") and port scans. The old 2.x release was Windows-only, but the new 3.X series runs on Linux, Mac, or Windows as long as Java is installed. Version 3.X omits the vampire zebra logo. As with all connect()-based scanners, performance on Windows XP SP2 and newer be poor due to limitations added to tcpip.sys. The FAQ provides details and workarounds. A short review was posted to nmap-dev in 2008.

Angry IP scanner shows you the ip addresses on the network. It is often the first tool I use when I visit a new location and want to see the network. A scan will help you place a new machine on a network without duplicating an ip address. It will also help you troubleshoot or get info to locate a machine.
Angry IP scanner is an old school tool that has held a place in my tool-box for a very long time. It's slim, and does exactly what it says it does. It's most certainly on on a level with Metasploit, but you don't always need to pen test a network to get the job done.
