A MAC address carries a specific bit, the second bit of its first byte, that tells a network whether the address was assigned by an actual hardware manufacturer or deliberately marked as locally administered, meaning it was made up for a specific purpose and isn't claiming to belong to any real registered device, which matters a great deal for a virtual machine or a container that needs a unique address without any risk of colliding with or impersonating real hardware. This tool generates random MAC addresses with that locally administered bit set correctly, safe for virtual network interfaces rather than mimicking a real manufacturer's address.
