If you were on a Windows computer and you need to know the MAC address it is using you can simply use IPCONFIG /ALL
in a command prompt. However, what if you don’t know anything more than the host name or IP address of a device, it is a bit more challenging.
This was just the situation a client of ours was facing. They knew that there was a device on their network using an IP address but they had no idea what it was and they needed to ensure at they didn’t have any rogue hardware infecting their company.
The solution was actually pretty easy but far from obvious. To find out what a device is from only the IP address follow these steps:
ping {name of the device}
, and press ENTER to get the IP addressarp -a
and press ENTER to see all of the devices your computer knows aboutAt this point they were able to figure out that it was a Hewlett-Packard device and because they had no HP PC ‘s laptops or servers they were able to narrow it down to an old network switch.
