And here is your Powershell script with the for loop: When MAC address resolution is enabled, Wireshark displays the MAC address.lookup when it encounters an IP address, to determine its associated domain. 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. To filter out a mac address in Wireshark, make a filter like so: not eth.addrF4-6D-04-E5-0B-0D. 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 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.
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. So, this short post is just to bring attention to a couple of potential useful sources for finding the vendor behind a MAC address. IEEE Registration Authority – Probably “the” database source you’d want to use. #Wireshark mac address lookup registration# You can access the info to the right under the Download section. Macaddress.io vendor database – This includes data from IEEE’s registry, but also includes information they’ve discovered on their own. They have an API you can tie into if you want. Wireshark OUI Lookup tool Found this and added it to the list. It uses IEEE’s registry plus a number of other sources. They have a regularly-updated printout of OUIs, and that link is on the referenced page (currently labeled ‘Wireshark Manufacturer Database’). I didn’t link to that page directly to save server load - it seems large. 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’m only looking for authoritative-type resources, rather than general search tools or one-off lists of MACs / OUIs. #Wireshark mac address lookup download#.#Wireshark mac address lookup registration#.
