Frequently asked questions
Everything you need to know about the MAC Address Lookup.
Back to the toolWhat is a MAC address?
A MAC address is a unique hardware ID of a network card, written as six pairs like 00:1A:2B:3C:4D:5E. The first three pairs (OUI) identify the manufacturer.
Why does my phone show “randomized” or no vendor?
Modern phones use a private random MAC address for each WiFi network to protect your privacy. These have the “locally administered” bit set and no vendor.
Where do I find a MAC address?
In your router’s connected devices list, in Windows with “ipconfig /all”, on macOS/Linux with “ifconfig”, or on the device label.
Can I find a device’s location from its MAC?
No. A MAC address is only visible on the local network and does not reveal location.
Is the vendor always accurate?
It is accurate for the original manufacturer of the network chip, which can be different from the brand on the device.
