arp-scan.exe is the Windows port of a fast ARP network scanner. It sends ARP requests on your local network to identify devices, collecting IPs, MAC addresses, and vendor data. It’s a command-line tool used for inventory, security audits, and quick network discovery.
This tool sends ARP probes on the chosen interface and parses replies to list active hosts with IP, MAC, and vendor information. It requires admin rights to access raw sockets and operates from the command line for automation.
Quick Fact: arp-scan originated as a lightweight discovery utility; it performs rapid ARP scans to enumerate hosts without needing full packet capture tools.
Yes, arp-scan.exe is Safe when downloaded from legitimate sources and used on networks you own or have explicit permission to scan.
The legitimate arp-scan.exe is not a virus. Malware may mimic the name, so verify signature and origin.
C:\Program Files\arp-scan\arp-scan.exe or C:\Program Files (x86)\arp-scan\arp-scan.exe. Any arp-scan.exe elsewhere is suspicious.Red Flags: If arp-scan.exe is located in unusual folders (e.g., Temp, AppData), runs when you’re not scanning, has no valid signature, or uses abnormal resources, scan with dedicated antivirus. Look for similarly named files like "arp-scan64.exe" from untrusted sources.

1. Quick Fixes:
2. 1. Run a targeted scan: arp-scan.exe -I <interface> <subnet> (e.g., arp-scan -I eth0 192.168.1.0/24)
3. 2. Limit scope and timeout: use options to reduce duration and scope.
4. 3. Ensure admin privileges are used only when required.
