How to Use the Network Scanner
This tool helps you analyze network scan results to identify which IP addresses are in use and which are available in your subnet. First, run a scan on your network using common tools like nmap, arp-scan, or the system arp command. Then paste the results here along with your subnet information to get a clear view of your IP utilization.
How to Run Network Scans
Linux / macOS
arp-scan -l
Requires: sudo apt install arp-scan on Linux
nmap -sn 192.168.1.0/24
Ping scan (no port scan) of your subnet
arp -a
View ARP table (shows already-known hosts)
Windows
arp -a
View ARP table (Command Prompt or PowerShell)
nmap -sn 192.168.1.0/24
Requires nmap: Download nmap

- Find available IPs: Know which addresses you can assign to new devices
- Identify conflicts: Spot duplicate IPs or unexpected devices
- Network planning: Document your IP usage for future reference
- Security: Spot unauthorized devices on your network
- Troubleshooting: Verify devices are accessible by IP address
