A Python tool that scans a LAN IP range using ICMP ping to find active devices.

• Takes a start and end IP address from the user
• Pings every IP in that range simultaneously using threads
• Shows which devices are Alive and which are Not Responding

• ICMP — ping protocol to check if a device is alive
• IP Addressing — scans a /24 subnet range
• LAN — works inside your local network
• Threading — all pings fire at the same time for speed

1. Open CMD
2. Navigate to this folder
3. Run the scanner:
4. Enter your IP range when asked: Start IP -> 192.168.1.1 End IP -> 192.168.1.20
