Nmap
Extensible, open-source network mapper with OS detection to scan networks for hosts and services.
What is Nmap?
Nmap ("Network Mapper") is a free and open source (license) utility for network exploration or security auditing. Many systems and network administrators also find it useful for tasks such as network inventory, managing service upgrade schedules, and monitoring host or service uptime. Nmap uses raw IP packets in novel ways to determine what hosts are available on the network, what services (application name and version) those hosts are offering, what operating systems (and OS versions) they are running, what type of packet filters/firewalls are in use, and dozens of other characteristics. It was designed to rapidly scan large networks, but works fine against single hosts. Nmap runs on all major computer operating systems, and official binary packages are avalable for Linux, Windows, and Mac OS X. In addition to the classic command-line Nmap executable, the Nmap suite includes an advanced GUI and results viewer (Zenmap), a flexible data transfer, redirection, and debugging tool (Ncat), a utility for comparing scan results (Ndiff), and a packet generation and response analysis tool (Nping).

Comments and Reviews
Said about Nmap as an alternative
Extremely versatile tool with a plethora of uses beyond just traceroute and ping functions.
Command line is generally more flexible than GUI and in this case the ability to use CIDR notation and specify ranges is a great improvement over Angry's simple start-stop.

I heard that this program was used by Carrie-Ann Moss's character, Trinity, in the movie, Matrix.
