Nmap Network Discovery and Mapping

Nmap is one of the most useful network discovery tools that we will ever use. Nmap allows you to explore networks of any size to determine the following information Port details, Host details, State, Service, Devices, Addresses, and much more. Nmap is one of those applications that we need to open anytime to see issues on the network, need to get information about hosts, track down an IP address, etc. Nmap is flexible, powerful, deployed all over the world. It is one among the top 10 programs. It is easy to use, well documented, cross platform and free. Nmap is one of the command line tool, but the same features also available in another front end tool Zenmap. To install Zenmap, we need to install Nmap along with it.
