arp-scan is an open source command-line networking utility that has been designed to send ARP (Address Resolution Protocol) queries to a specified target (network interface). After that, it displays any responses that are received, such as IP address, hardware address, as well as vendor information.

arp-scan is engineered in such a way that it allows users to change any part of the outgoing ARP packets, in order to examine non-standard ARP packets. It is comprised of arp-fingerprint, a small command-line tool that allows a system to be fingerprinted.

arp-scan is a multi-platform software that has been successfully tested on Linux, FreeBSD, OpenBSD, NetBSD, DragonflyBSD, Solaris, and Mac OS X operating systems.

What's New in This Release:
  • Updated IEEE OUI and IAB MAC/Vendor files. There are now 18157 OUI entries and 4414 IAB entries.
  • Use autoconf 2.69 and automake 1.11 to add support for ARM 64-bit CPUs.
  • Use libpcap functions to obtain the interace IP address and send the ARP packet, instead of using our own link-layer specific functions. The only link-layer specific function that we still need is get_hardware_address() to obtain the interface MAC address. This means we now require libpcap 0.9.3 or later.
  • Added support for Dragonfly BSD.
