If you have any other resources that you use to look up the vendor behind a MAC address, let me know and I can include it here. I didn’t link to that page directly to save server load - it seems large. They have a regularly-updated printout of OUIs, and that link is on the referenced page (currently labeled ‘Wireshark Manufacturer Database’).

It uses IEEE’s registry plus a number of other sources.

IEEE Registration Authority – Probably “the” database source you’d want to use. So, this short post is just to bring attention to a couple of potential useful sources for finding the vendor behind a MAC address. I tend to default to using the MAC / OUI Lookup tool at, but after a few failed attempts, I started looking for source lists after noticing they may not keep their database updated. To get the mac address, type ncpa.cpl in the Windows search, which will bring you here: Right click the connection, go to ‘Status’: Then, go to details: And write down the value listed in Physical Address. So you don’t have to use this Powershell script, but you could if you want to.I find myself looking up mac addresses semi-regularly, trying to find the vendor behind a device connected to our equipment at a customer’s house, or looking through logs and trying to identify devices attempting to connect to our wireless APs. To filter out a mac address in Wireshark, make a filter like so: not eth.addrF4-6D-04-E5-0B-0D. It takes a while for the loop to run, but you will get a nice output of all the MAC addresses and their corresponding vendors.Īfter writing this script, and thinking it was so useful, I found this link to a MAC address lookup that lets you do multiple searches. lookup when it encounters an IP address, to determine its associated domain.

And here is your Powershell script with the for loop: When MAC address resolution is enabled, Wireshark displays the MAC address.

Save the text file in the same directory as your Powershell script.

Copy and paste the MAC addresses from your switch into a text file.

Because a MAC address table often has more than one device we can run a for loop in powershell that gets the manufacturer for each MAC address you have in the MAC address table. $macvendor = (($webrequest.Content -split ’\,’) -split ’"’)īut we can do better than that. At Layer 2, computers have a hardware or MAC address. Network addressing works at a couple of different layers of the OSI model. As the name suggests, it is designed to resolve IP addresses into a form usable by other systems within a subnet. $webrequest = Invoke-WebRequest -Uri “$mymac/csv” The Address Resolution Protocol (ARP) was first defined in RFC 826. We can do the same thing with this following Powershell script: I made repeated attempts to use both WireShark 1.12.4 and 1.99.3, but without success. Some of this has been shared before, but there is a little added twist at the end which worked for me. Then you go to and paste in your MAC address, and you’ll see that from the burned-in address, the hardware you’re using is an Apple device. This may possibly be of help to other new WireShark users who are having trouble getting WireShark to launch in Yosemite. Here’s an example: You find that the MAC address of your computer is C8-BC-C8-12-34-56. So when you’re administering network equipment, sometimes you do a MAC address lookup to see what kind of devices are attached to a switch.

Yay! Ok, next, the switch has some tool called a MAC address table which keeps a table of IP addresses and their corresponding MAC addresses.

So now the PC has an IP address and a MAC address. In a little more detail, PC’s have a MAC address, and usually the router provides an IP address for the PC. From what I learned in my CCNA bootcamp class, your PC gets connected to the internet through something like this: PC -> switch -> router -> ISP -> Magical Awesome internet.
