arp-scan is a command-line network scanning tool that uses ARP requests to discover and fingerprint IPv4 hosts on a local network. It is written in C, uses libpcap, and runs on Linux, BSD, macOS, and Solaris under the GPLv3 license.
Use cases
- discover all devices on my local network
- find unknown hosts connected to my LAN
- fingerprint network devices by MAC address
- scan a subnet for live IPv4 hosts
- detect rogue devices on the network
- map IP addresses to MAC addresses
When to choose
- you need fast local network host discovery on Unix-like systems
- you want ARP-based scanning that works without IP connectivity to targets
- you need MAC address vendor fingerprinting of LAN devices
When to avoid
- you need to scan hosts across routers or the internet (ARP is link-local only)
- you need IPv6 discovery
- you need a GUI-based network scanner
