Which company owns MAC address prefix 7C:02:BC?

MAC address prefix 7C:02:BC is registered to Hansung Electronics Co. LTD in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 7C:02:BC has a network interface built by Hansung Electronics Co. LTD.

What is the OUI 7C:02:BC?

7C:02:BC is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Hansung Electronics Co. LTD. It covers every address from 7C:02:BC:00:00:00 to 7C:02:BC:FF:FF:FF, or 16,777,216 addresses in total. It is also written 7C-02-BC.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 7C:02:BC:00:00:00 that is 7C:02:BC — 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 Hansung Electronics Co. LTD located?

Hansung Electronics Co. LTD is listed at 319, Bong san-ri, San dong-myun Gumi KR 730-853 in the IEEE OUI registry entry for 7C:02:BC. This is the address the organization registered with the IEEE, which may differ from its current operating address.
