It can also be used for scanning hub/switched networks. Netdiscover is used for the active or passive scanning of those wireless networks without the DHCP server. Both the tools Uses ARP Packets to get this information.

Each system will then respond with their IP address and the switch or other device will then create a small database that maps the MAC to the IP address, so that it it knows 'who is who'. The router and switches send out broadcast ARP requests to all the MAC addresses on the network asking them to respond with their IP addresses. These tools are basically used in Penetration Testing of Wireless Networks and can be used to get to know who is in the Network by knowing their IP Address and MAC Address.ĪRP (Address Resolution Protocol) is used to map MAC addresses to IP addresses on an internal network. You can Use a number of tools for thus task such as Netdiscover, arp-scan, nmap and even WireShark.
