MAC addresses

[Ext User(PeterThorne)]

Every networked device, including LAN cards, smart-phones, network printers
etc, has a unique MAC address.

How are these MAC addresses allocated? Is there an international body that
allocates these addresses to manufacturers?

That is the idea, but some can be changed by bios, softwae, etc.

The first part is allocated to the manufacturer or
close and they get to allocate the rest themselves.

Only the part that identifys the manufacturer or close.
