🔍 MAC Address Facts
Structure
A MAC address is 48 bits (6 bytes) typically represented as 12 hex digits in six groups (e.g., 00:1A:2B:3C:4D:5E).
OUI
The first 3 bytes (Organizationally Unique Identifier) identify the manufacturer, assigned by IEEE.
Uniqueness
Each network interface should have a globally unique MAC address assigned by the manufacturer.
MAC vs IP
MAC addresses operate at Layer 2 (Data Link) while IP addresses operate at Layer 3 (Network).
Privacy
Some devices now use randomized MAC addresses for privacy when scanning networks.
Broadcast
The broadcast MAC address (FF:FF:FF:FF:FF:FF) sends packets to all devices on a local network.
Dark Mode
Note: This tool uses the IEEE OUI database and other public sources. Some manufacturers may use multiple OUI prefixes or share them with subsidiaries. Results should be verified for critical applications.
