computer/network knowledgibles
 
:-k Got a bit of a problem wondering if anyone can give me a hand.
I need to find the IP address of a device on my network, the **** that was here before me messed with my switch and didn't record the details. All I have is the physical box, it's mac address and it's serial number. I can't nuke it as the only way to do so is with a command line through a console cable which apparently no one in sheffield knows what it is.

Any ideas?

cmd -> ipconfig?

ping the whole network, then run arp -a and look for the mac address.

Would that have the same result as scouring my dhcp pool for the mac address?

worth a pop anyway cheers ophic :)

Not really, I would never put static devices on dhcp, unless with a reserved address.

Not quite - my method would work regardless of whether it uses dhcp or not :cool:

We've had a new server meaning the reservation for the switch has gone, and there is no record of it's ip address (unless it is getting it from dhcp) so I want to find the IP to give it a reservation and hopefully it'll start behaving.

Switches normally have a console port, can you not login directly to the switch via that and find the IP address?
