About MAC Vendor Lookup

MAC Vendor Lookup helps you identify the manufacturer of a network device using its MAC address. A MAC address is a unique hardware identifier used by network devices like routers, switches, mobile phones, WiFi adapters, and IoT devices. The first part of a MAC address is called the OUI (Organizationally Unique Identifier), which indicates the vendor or brand.

Why MAC Vendor Lookup is Useful

  • Identify unknown devices connected to your network
  • Detect unauthorized WiFi users by vendor name
  • Network inventory and troubleshooting
  • Security investigation and device monitoring

How to Use

  1. Enter a MAC address (example: FC:FB:FB:12:34:56)
  2. Click lookup to view the vendor name
  3. Use results to recognize the device brand

FAQ

Does this tool show the exact device model?
No. It shows only the manufacturer/vendor based on the MAC OUI prefix.

Can MAC addresses be changed?
Yes. Some devices support MAC randomization, which may affect vendor identification.
