Step 1: Ping the broadcast address on your network from any Windows machine.
If your subnet is 192.168.1.x with a mask of 255.255.255.0, then you would ping 192.168.1.255. Don’t be concerned about the “Request timed out” messages.
C:\Users\Demo>ping 192.168.1.255 Pinging 192.168.1.255 with 32 bytes of data: Request timed out. Request timed out. Request timed out. Request timed out. Ping statistics for 192.168.1.255: Packets: Sent = 4, Received = 0, Lost = 4 (100% loss),
Step 2: Use the ARP (Address Resolution Protocol) command to check the ARP table. Type in the following command:
ARP will display a list of IP and MAC addresses of all the connected devices on the network, except the device you issued the ping from.
