arp-scan sends ARP (Address Resolution Protocol) queries to the specified targets, and displays any responses that are received.

It allows any part of the outgoing ARP packets to be changed, allowing the behavior of targets to non-standard ARP packets to be examined. The IP address and hardware address of received packets are displayed, together with the vendor details.

These details are obtained from the IEEE OUI and IAB listings, plus a few manual entries. It includes arp-fingerprint, which allows a system to be fingerprinted based on how it responds to non-standard ARP packets.

What's New in This Release:
Support was added for BSD systems (FreeBSD, OpenBSD, NetBSD, and Mac OS X).
Startup time and memory usage were reduced for large target networks.
Operation of the --srcaddr option was improved.
All ethernet frame fields and ARP packet fields can now be controlled. Documentation was improved. IEEE OUI and IAB listings were updated.
Additional fingerprints were added for arp-fingerprint.
