The online MAC Address Generator is used to generate a random MAC address, in lower or upper case for your convenience. The tool can generate four most commonly used types of MAC address formats and it is also allowed to specify your preferred MAC address prefix (specific OUI - Organizationally Unique Identifier).
Please not the generated MAC addresses are for testing purpose only, not for production use.
MAC address (Media Access Control address) is a unique identifier assigned to network interfaces for communications on the physical network segment. It usually encodes the manufacturer's registered identification number.
If you want to find a list of MAC address prefixes based on the manufacturer, please use our MAC address lookup tool.
