arp-scan is a command-line tool for system discovery and fingerprinting.
It constructs and sends ARP requests to the specified IP addresses,
and displays any responses that are received.
arp-scan allows you to:
* Send ARP packets to any number of destination hosts, using a
configurable output bandwidth or packet rate.
This is useful for system discovery, where you may need
to scan large address spaces.
* Construct the outgoing ARP packet in a flexible way.
arp-scan gives control of all of the fields in the ARP
packet and the fields in the Ethernet frame header.
* Decode and display any returned packets.
arp-scan will decode and display any received ARP packets
and lookup the vendor using the MAC address.
* Fingerprint IP hosts using the arp-fingerprint tool.
