How It Works
A MAC (Media Access Control) address is a 48-bit identifier assigned to network interface controllers. It consists of 6 bytes (12 hex digits), typically displayed in groups of two separated by colons or hyphens.
This generator creates random 6-byte values using crypto.getRandomValues() and formats them according to your chosen notation. The generated addresses are locally administered (the second-least significant bit of the first octet is set) to avoid conflict with real manufacturer OUI assignments.
Random MAC addresses are useful for testing network configurations, virtual machine setups, and privacy-focused scenarios.
