Netdiscover

Netdiscover is a handy tool designed to help you find network addresses, especially useful for those wireless networks that don’t have DHCP servers. But don’t worry, it also works well on wired networks! It sends out ARP requests and listens for replies, making it pretty effective at what it does.

Requirements for Using Netdiscover

Before you dive in, make sure you have these:

\n
• libnet 1.1.x
\n
• libpcap

\n
• The packet length count display has been fixed.
\n
• Now includes sender data in the stations list from ARP requests.
