arp-scan sends ARP queries to specific targets and shows any received responses, making it a useful network scanning tool.
Additionally, arp-scan includes arp-fingerprint, which allows users to fingerprint a system based on its response to non-standard ARP packets. The software is continually being improved and updated, with some of the notable new features in the latest version including the ability to save ARP response packets to a pcap file for later analysis using the --pcapsavefile option.
The software also has a new --vlan option that enables users to create outgoing ARP packets with an 802.1Q VLAN tag, as well as a new --llc option for creating outgoing ARP packets with RFC 1042 LLC/SNAP framing. Users also get new ARP fingerprints, while the IEEE OUI and IAB files that the software relies on have been updated to ensure the most up-to-date information. Overall, arp-scan is highly recommended for anyone looking to analyze and examine ARP behavior.
