What is a MAC Address?
Every device that connects to the internet has a "Social Security Number" for its hardware. This is called a MAC Address (Media Access Control). While an IP address can change depending on where you are, a MAC address is permanently burned into your device's Wi-Fi or Ethernet card at the factory.
Can websites see my MAC?
No! Standard websites cannot see your MAC address. Only your Router or someone on your local Wi-Fi can see it. This makes it a very safe way to identify devices in your own home or office.
How We Identify the Manufacturer
A MAC address has 12 characters. The first 6 characters are a special code called an OUI (Organizationally Unique Identifier). Every company in the world that makes electronics, like Apple, Samsung, or Sony, has their own unique OUI codes.
Our MAC address lookup tool searches a giant global database to find which company owns that specific OUI. This tells you exactly who made the device in less than a second.
Why is this tool helpful?
- Identify Intruders: If you see a strange device connected to your Wi-Fi, use this tool to see if it is just your smart fridge or a neighbor's phone.
- IT Troubleshooting: Network experts use this to find out which brand of server or switch is having a problem.
- Check Authenticity: If you bought a "Cisco" router but the MAC lookup says it was made by a different, unknown company, it might be a fake.
Frequently Asked Questions
How do I find my own MAC address?
On a Windows PC, open the Command Prompt and type ipconfig /all. On an iPhone or Android, look under Settings > General > About.
Why does it say "Vendor Not Found"?
Many modern phones use "MAC Randomization" for privacy. They create a fake, temporary MAC address when connecting to public Wi-Fi. These fake addresses aren't in any database.
