In the "Network" section of Windows 7, I can see a new device connected to the network. I'm not sure what that device is , so I intend to block it from the network at the router level - mostly to see if something goes wrong so at least we'll know what's connected to it.
However to do that I'll need its MAC address - which I can obtain from the router itself - provided I obtain its local ip address somehow.
Is there a way of doing so ? I don't have access to this device, and assume that there are too many devices connected for me to whitelist. What I basically want is to turn a network path "\....." to an ip address.
I tried pinging it. However the name of this device is just numbers, so ping is resolving it to a 0.0.0.x ip address which fails.
EDIT (to clarify):
I don't need to get the Mac/IP address of this machine I'm on. What I need is to get the Mac/Ip address of another device which is connected to the same network as this machine and which I can observe from network. I have no idea what this device is and I have no access to it.
