Which company owns MAC address prefix BC:8C:CD?

MAC address prefix BC:8C:CD is registered to SAMSUNG ELECTRO-MECHANICS(THAILAND) in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with BC:8C:CD has a network interface built by SAMSUNG ELECTRO-MECHANICS(THAILAND).

What is the OUI BC:8C:CD?

BC:8C:CD is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to SAMSUNG ELECTRO-MECHANICS(THAILAND). It covers every address from BC:8C:CD:00:00:00 to BC:8C:CD:FF:FF:FF, or 16,777,216 addresses in total. It is also written BC-8C-CD.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in BC:8C:CD:00:00:00 that is BC:8C:CD — 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.

Where is SAMSUNG ELECTRO-MECHANICS(THAILAND) located?

SAMSUNG ELECTRO-MECHANICS(THAILAND) is listed at 93Moo5T. Bangsamak Bangpakong US 24180 in the IEEE OUI registry entry for BC:8C:CD. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does SAMSUNG ELECTRO-MECHANICS(THAILAND) own?

SAMSUNG ELECTRO-MECHANICS(THAILAND) holds 34 OUI prefixes in the IEEE registry, of which BC:8C:CD is one. A device made by SAMSUNG ELECTRO-MECHANICS(THAILAND) could carry a MAC address from any of them.
