About MAC Address Lookup

The MAC Address Lookup tool is a specialized network utility designed to identify the manufacturer of a network device using its unique hardware address. Every network interface card (NIC), whether Wi-Fi, Ethernet, or Bluetooth, has a globally unique identifier called a Media Access Control (MAC) address. The first half of a MAC address (the first 6 characters) is known as the Organizationally Unique Identifier (OUI), which is assigned to specific manufacturers like Apple, Cisco, Intel, or Samsung. By checking this OUI against the global IEEE database, this tool can instantly tell you who made the device, which is incredibly useful for network administration, security auditing, and troubleshooting unknown devices on your network.
