About MAC Addresses
A Media Access Control (MAC) address is a unique identifier assigned to a network interface controller (NIC) for use as a network address in communications within a network segment. This tool is useful for network administrators and developers who need to validate MAC address formats or generate new ones for testing purposes, such as in virtual machine configurations or network simulations. Our validator checks against the standard format (six groups of two hexadecimal digits, separated by hyphens or colons), and the generator creates a new, random, and correctly formatted MAC address with a single click.
