netdiscover binary package in Ubuntu Focal ppc64el

 Netdiscover is an active/passive address reconnaissance tool, mainly
 developed for those wireless networks without dhcp server, when you
 are wardriving. It can be also used on hub/switched networks.
 .
 Built on top of libnet and libpcap, it can passively detect online
 hosts, or search for them, by actively sending ARP requests.
 .
 Netdiscover can also be used to inspect your network ARP traffic,
 or find network addresses using auto scan mode, which will scan for
 common local networks.
 .
 Netdiscover uses the OUI table to show the vendor of the each MAC
 address discovered and is very useful for security checks or in
 pentests.
