Answer: Nmap

Explanation:

Nmap is a free open-source utility for network exploration and security auditing. It is used to
discover computers and services on a computer network, thus creating a “map” of the network.
Just like many simple port scanners, Nmap is capable of discovering passive services. In addition,
Nmap may be able to determine various details about the remote computers. These include
operating system, device type, uptime, software product used to run a service, exact version
number of that product, presence of some firewall techniques and, on a local area network, even
vendor of the remote network card. Nmap runs on Linux, Microsoft Windows, etc.
