About MAC Addresses
What is MAC Address?
Media Access Control (MAC) address is a unique 48-bit identifier assigned to network interface controllers. It's used for communication within a network segment.
OUI (Vendor Prefix)
The first 3 bytes (6 characters) identify the manufacturer through the Organizationally Unique Identifier (OUI) registered with IEEE.
MAC Randomization
Modern devices randomize MAC addresses when scanning WiFi networks for privacy. This prevents tracking users across locations.
