Random MAC Address Generator
Generate random, valid MAC addresses in your choice of format.
A MAC address is the 48-bit hardware identifier every network interface carries, written as six pairs of hex digits. Developers and network engineers frequently need valid-looking MAC addresses for testing device provisioning, populating databases, configuring virtual machines, or scripting network simulations — and inventing them by hand risks producing malformed ones.
This generator produces random, well-formed MAC addresses in colon, hyphen or dot notation, with the locally-administered bit set so they won't collide with real vendor-assigned hardware. Generate one or a batch, and copy whichever format your tooling expects.
