About:
arp-scan is a command-line tool that sends ARP requests to discover active hosts on a local network. It can identify all IPv4 devices connected to a subnet, even those blocking other port scanning methods. The tool also attempts to fingerprint operating systems by analyzing ARP response characteristics.

Key Features:

Fast and low-level network discovery using ARP requests
Operating system fingerprinting via vendor ID and MAC address analysis
Customizable packet generation and output formatting
Supports parsing of nmap-style MAC address vendor files

Use Cases:

Network inventory and asset discovery for system administrators
Security auditing to identify unauthorized devices on a network
Troubleshooting connectivity issues by verifying host presence

Alternatives:

nmap – More comprehensive scanning suite that includes ARP discovery but is heavier
arping – Focuses on host liveness verification rather than bulk network scanning
