MAC Lookup: Identify Hardware Makers

Who made that device on your Wi-Fi? Enter a MAC address below to find out if it's an Apple, Samsung, Cisco, or a hidden brand.

Quick Tool Fact

Every network device has a unique "Physical Address" called a MAC address. The first half of this address (the OUI) tells you exactly which company built the hardware. It is like a digital fingerprints for your Wi-Fi card.

What is a MAC Address?

Every device that connects to the internet—like your phone, gaming console, or smart fridge—has a unique name plate. This is called a MAC (Media Access Control) Address. Unlike an IP address, which changes depending on where you are, a MAC address is permanent. It is like the serial number engraved on a bicycle's frame; it tells us who made the hardware.

Identify Strangers

If you see an unknown device on your Wi-Fi, use AirOI Checker to find the brand. If it's a "Samsung" and you don't own one, someone might be stealing your internet!

Privacy First

Standard websites cannot see your MAC address. Only devices on your local home network can see it. It is very safe to use this lookup tool.

How to find your MAC Address

Depending on your device, finding your MAC address is quite simple:

  • Windows: Open CMD and type ipconfig /all. Look for "Physical Address."

  • Android/iPhone: Go to Settings > About Phone > Status or Wi-Fi settings.

Why do some MACs show "Not Found"?

Modern phones often use "MAC Randomization" to stop stores and hackers from tracking you. They create a fake, temporary address. If our tool can't find the brand, the device is likely using this privacy feature!

Frequently Asked Questions

Can I find a person's name from a MAC address?

No. A MAC address only reveals the company that made the hardware (like Apple or Intel). It does not contain any personal names or phone numbers.

What is an OUI?

OUI stands for Organizationally Unique Identifier. It is the first 6 characters of the address that are assigned to companies by the IEEE.

Is a MAC address the same as an IP address?

No! An IP address is like your current mailing address (where you are sitting). A MAC address is like your actual name or fingerprints (it stays with the device forever).
