Which company owns MAC address prefix FC:00:12?

MAC address prefix FC:00:12 is registered to Toshiba Samsung Storage Technolgoy Korea Corporation in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with FC:00:12 has a network interface built by Toshiba Samsung Storage Technolgoy Korea Corporation.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in FC:00:12:00:00:00 that is FC:00:12 — and look that prefix up in the IEEE OUI registry. If the second-lowest bit of the first octet is set, the address is locally administered (a randomized or private MAC), which belongs to no manufacturer and will not resolve; modern phones and laptops use these by default on each network.
