MAC Address Lookup: Find Device Vendors

Identify the manufacturer of any network device instantly. Enter a MAC address to search the global OUI database for Apple, Samsung, Cisco, and more.

AI Overview

A MAC Address Lookup identifies the hardware maker of a device by checking the first six digits (the OUI prefix). Every Wi-Fi and Ethernet card has a unique physical address assigned at the factory. This tool helps you recognize unknown devices on your router and verify hardware authenticity.

What is a MAC Address?

A MAC (Media Access Control) Address is a unique 12-digit hexadecimal identifier assigned to every network interface. Unlike an IP address, which identifies your location on a network, a MAC address identifies the actual hardware. It is often referred to as the Physical Address or Hardware ID.

Security Note: Standard websites cannot see your MAC address. Only devices on your local network (like your router) or local software can read this hardware identifier.

How to Identify a Device Manufacturer

Hardware makers are assigned specific blocks of addresses called OUIs (Organizationally Unique Identifiers). By looking up the first half of a MAC address in the IEEE database, you can determine if a device was made by Apple, Intel, Samsung, or a specialized chipset maker.

Why Perform a MAC Lookup?

  • Identify Unknown Devices: Check your router’s connected list to see who is using your Wi-Fi.
  • Inventory Management: IT teams use this to categorize hardware across a corporate network.
  • Troubleshooting: Verify if a specific network card is causing connectivity issues.
  • Security Audits: Detect MAC Spoofing if a device identifies as a vendor that doesn't match the actual hardware.

Frequently Asked Questions

How do I find my MAC address?
On Windows, type ipconfig /all in the Command Prompt. On Android/iOS, look under "About Phone" or "Wi-Fi Settings."

Can I find a name or location?
No. A MAC address only reveals the manufacturer, not the owner’s name or physical GPS location.

What is MAC Randomization?
Modern smartphones generate fake MAC addresses for public Wi-Fi to prevent tracking. These addresses usually show "Vendor Not Found."
