Which company owns MAC address prefix BC:8A:A3?

MAC address prefix BC:8A:A3 is registered to NHN Entertainment in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with BC:8A:A3 has a network interface built by NHN Entertainment.

What is the OUI BC:8A:A3?

BC:8A:A3 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to NHN Entertainment. It covers every address from BC:8A:A3:00:00:00 to BC:8A:A3:FF:FF:FF, or 16,777,216 addresses in total. It is also written BC-8A-A3.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in BC:8A:A3:00:00:00 that is BC:8A:A3 — 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 NHN Entertainment located?

NHN Entertainment is listed at Play Museum, 629 Sampyeong-dong, Bundang-gu Seongnam-si, Gyeonggi-do KR 463-400 in the IEEE OUI registry entry for BC:8A:A3. This is the address the organization registered with the IEEE, which may differ from its current operating address.
