What is a MAC Address?
A MAC (Media Access Control) address is a unique identifier assigned to network interface controllers. It's a 48-bit address usually displayed as six groups of two hexadecimal digits.
This tool generates locally administered MAC addresses (LAA) by default, which are safe to use for testing without conflicting with real hardware addresses.
