How to find network device using it’s manufacturer name?

I’ve previously posted a note about finding Raspberry Pi without knowing it’s ip address. Well, basically it’s the same… Only you need to change MAC prefix to find other manufacturer. To wrap this is up, this is a command to find device by MAC prefix:

sudo nmap -sP 192.168.100.0/24 | awk '/^Nmap/{ip=$NF}/00:D0:23/{print ip}'

And here you can find actual MAC information (use CTRL+F).

Of course you need Nmap to do that! And sudo is necessary!

Beware that sometimes there might be many prefixes for one manufacturer. Also check company name precisely, for example HP is Hewlett Packard but it also can be ProCurve Networking by HP.

My own supercomputer!

…well it’s not exactly a supercomputer. It’s an 8 core AMD, NVIDIA 1050 Ti, Linux running machine designed for everyday working and some AI tests. I’ve decided with my girlfriend that we should name it to honor woman in computing industry — therefore please meet Maria.

How to find Raspberry Pi using MAC address

When you want to find your headless but networked Raspberry Pi and you’re lazy like me use nmap:

sudo nmap -sP 192.168.1.0/24 | awk '/^Nmap/{ip=$NF}/B8:27:EB/{print ip}'

Mask /24 means that addresses from 192.168.1.0 to 192.168.1.254 will be searched. You can extend that to /16 if you don’t know subnet of your device.
