About MAC Address Generator
Generated addresses are unicast and locally administered by default - the second-least-significant bit of the first byte is set, which marks the address as assigned by you rather than from an IEEE-registered block. That is the correct choice for test data, VMs and containers, because it cannot collide with a real manufacturer's address.
Untick that option to generate an address in a registered vendor's range instead, which is what you want when something needs to look like a particular kind of hardware.
