🔗 Random MAC Address Generator

Generate random MAC addresses in batch with four formats, case toggle, unicast/multicast & UAA/LAA control, custom OUI prefix, and vendor presets

-

Separator

Case

Address Type

Administration

Formats: 00:50:56, 005056, 00-50-56
💡 When OUI prefix is set, address type and administration type still override bit 0 and bit 1 of the first byte.

Vendor Presets

A MAC address (Media Access Control Address) is a 48-bit hardware identifier for network devices, consisting of 6 hexadecimal bytes. This tool generates random MAC addresses compliant with IEEE 802 standards entirely in your browser, supporting four formats: colon-separated (AA:BB:CC:DD:EE:FF), hyphen-separated (AA-BB-CC-DD-EE-FF), Cisco dot notation (AABB.CCDD.EEFF), and no separator (AABBCCDDEEFF). Configure unicast/multicast type (byte 0 bit 0), UAA/LAA administration type (byte 0 bit 1), custom OUI prefix, and vendor presets for VMware/VirtualBox/Hyper-V/QEMU, with batch generation up to 100. All generation uses the browser's built-in crypto.getRandomValues — input data is not uploaded by the tool.
