![]() ![]() 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. And here is your Powershell script with the for loop:.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.Uses Wireshark's manufactures database of OUIs (Organizationally Unique Identifier). ![]() 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. Install-Package MacAddressVendorLookup -Version 1.1.4. ![]() $macvendor = (($webrequest.Content -split ’\,’) -split ’"’)īut we can do better than that. $webrequest = Invoke-WebRequest -Uri “$mymac/csv” We can do the same thing with this following Powershell script: 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. 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. Wireshark mac address lookup Pc#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. The vendor of any particular OUI may be determined by checking the IEEE MAC database, or the Wireshark OUI Lookup Tool. Ok so the point of all the background information is that stuff that gets connected to the internet has to have a MAC address. Manufacturer’s registered identification number and may be referred to If assigned by the manufacturer, a MAC address usually encodes the Notice in Figure 3-13 that the MAC address of the device is referenced. And MAC addresses are most often assigned by the manufacturer of a network interface controller (NIC) and are stored in its hardware. by a Wireshark capture, you can use an online MAC address lookup table. According to Wikipedia, a MAC address is a unique identifier assigned to network interfaces for communications on the physical network segment. ![]()
