MAC address lookup

Find out which company made a device on your network from its MAC address — handy when your router lists an unknown device.

Any format: colons, hyphens, dots or none. Only the first half (the manufacturer prefix) is sent for the vendor lookup.

How MAC vendor lookup works

The first three bytes of a MAC address are the Organizationally Unique Identifier (OUI), which the IEEE assigns to manufacturers. Looking up the OUI identifies the maker of the network chip — not necessarily the brand of the finished product.

Randomised (private) MAC addresses

Modern phones and laptops use a different random MAC for each Wi-Fi network to protect privacy. These addresses have the “locally administered” bit set and have no manufacturer, so an unknown device in your router's list may simply be a phone using private addressing. Check the device list in your router's admin page to match names.

Finding a device's MAC address

  • Windows: run getmac or ipconfig /all (Physical Address).
  • macOS: System Settings → Network → Wi-Fi → Details → Hardware.
  • Android: Settings → About phone → Status (or the Wi-Fi network's details for the per-network address).
  • iPhone: Settings → Wi-Fi → tap the network → Wi-Fi Address.

Questions

Can a MAC address identify a person?

No. It identifies a network interface, visible only on the local network — websites never see it.
