Using netdiscover in Kali Linux to identify devices on a network

We’ll start off our network host discovery by first using a very simple tool known as netdiscover. The netdiscover tool comes preinstalled in Kali Linux; however, you can install it on almost any version of Linux using the following command:

sudo apt install netdiscover

netdiscover, as the name suggests, is used to discover online hosts on a wired or wireless network by broadcasting Address Resolution Protocol (ARP) requests. What makes netdiscover easy to use is that it allows users to automatically scan an entire range or subnet of IP addresses on a network to detect online hosts. Another very useful feature of netdiscover is that it displays the Media Access Control (MAC) address along with the vendor of the device or Network Interface Card (NIC), which can make host discovery much simpler when trying to differentiate between end user, server, and networking devices.
