A free online MAC address generator for network testing and development. Generate 1-50 random MAC addresses with configurable output format (colon-separated, hyphen-separated, Cisco-style dotted, or no separator), uppercase or lowercase letters, and optional vendor OUI prefix selection from major manufacturers including Cisco, Google, Apple, VMware, Intel, Dell, and more. Download results as a CSV file. All generation is local and instant.

Yes. The generated addresses follow the IEEE 802 standard format of six 2-digit hexadecimal octets. When using a vendor OUI, the first three octets match the manufacturer's registered prefix.
Generated MAC addresses are syntactically valid but should only be used for testing and development. Using unassigned MAC addresses on production networks may cause conflicts.
