Re: Which machine responds to a ping?
You can also check the ARP table on the receiving machine. The command to
use is 'arp -a' from the cmd shell.
That will show you the hardware MAC address, mapped to the IP address, of
anything that's tried to connect to it. You could then compare that MAC
info to your other devices on your network. An 'ipconfig /all' cmd on a PC
will tell you it's MAC address. Other equipment like printers or routers
will often have that on a serial number label. The info may shed additional
light on what's connected to your network.
Your question would probably be better asked on a forum for that netgear
