What is the Proxmox MAC address block or range?

[IlyasNL]

Like the subject says really.
For $reasons I need to create a new VM from the command line. For the network adapter I need to specify a MAC address.

To this end, I'm wondering if Proxmox has registered a MAC(OUI) block or range or prefix which we could use to generate out MAC's from.
I mean I can pick one at random but I'd prefer to do it properly if I can.

Does anyone know?

Hi,
by default it's random, but you can define a custom prefix in datacenter options.
