Netdiscover is simply a scanner that leverages the Address Resolution Protocol (ARP) to discover connected clients on a network segment. ARP operates between the data link layer (layer 2) and the network layer (layer 3) of the OSI reference model. Devices use ARP to resolve IP addresses to MAC addresses for local communication.
To perform an internal network scan with Netdiscover, observe the following steps:
- Execute the following commands:
netdiscover -r <network-ID>/<network prefix>netdiscover -r 10.10.10.0/24
Netdiscover will begin to display all active devices, displaying their IP addresses, MAC addresses, the vendors of their network interface cards (NICs), and their hostnames, as shown in the following screenshot: ...
