About MAC Addresses

MAC Address Format

A MAC (Media Access Control) address is a 48-bit (6-byte) hardware identifier assigned to network interfaces. It is typically displayed as six pairs of hexadecimal digits.

OUI

The first three bytes of a MAC address represent the Organizationally Unique Identifier (OUI), which identifies the manufacturer. Randomly generated MACs do not correspond to real OUIs.

Testing Use

Random MAC addresses are useful for testing network applications, simulating devices, and data anonymization in network logs.
