Little help please Network Gurus

[Pumpkinstew]

I'm using a standalone network and have a web-cam attached. You dial into it simply by putting the IP address into a browser and the image shows up on screen. Dead easy.

Sadly the IP address has been lost in the mists of time and no-one saw fit to write it down.
The mac address is helpfully stuck on the camera so.... any way of determining the IP of a device from the mac id?

If your network range is 192.168.0.0 - 192.168.0.255 then from a machine in that subnet ping the broadcast address (192.168.0.255 in this case) then open a command prompt and do 'arp -a' and you'll get a list of MAC addresses and associated IP addresses.

Cheers, Burble.

I'll give that a try tomorrow.

Alternatively, some routers have ways to list local IP addresses they know about. Obviously depends on the router you've got whether (and how) you can do that.

Surely the web cam is attached to a PC and that's the IP address you're looking for? Or is the camera a standalone device?

Standalone I assume.

Yeah, the cam is standalone. Turns out the archaic BNC wiring that the camera is connected to is knackered anyway so it's all been a bit futile. The arp -a command is pretty useful for the future though.

nmap will tell you all! You can get a windows version too which has a GUI called Zenmap.
