Which company owns MAC address prefix D8:BF:4C?

MAC address prefix D8:BF:4C is registered to Victory Concept Electronics Limited in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with D8:BF:4C has a network interface built by Victory Concept Electronics Limited.

What is the OUI D8:BF:4C?

D8:BF:4C is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Victory Concept Electronics Limited. It covers every address from D8:BF:4C:00:00:00 to D8:BF:4C:FF:FF:FF, or 16,777,216 addresses in total. It is also written D8-BF-4C.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in D8:BF:4C:00:00:00 that is D8:BF:4C — 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 Victory Concept Electronics Limited located?

Victory Concept Electronics Limited is listed at 4/F., CAC Tower, Kwun Tong Kowloon HK KLN in the IEEE OUI registry entry for D8:BF:4C. This is the address the organization registered with the IEEE, which may differ from its current operating address.
