Which company owns MAC address prefix CC:47:03?

MAC address prefix CC:47:03 is registered to Intercon Systems Co., Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with CC:47:03 has a network interface built by Intercon Systems Co., Ltd..

What is the OUI CC:47:03?

CC:47:03 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Intercon Systems Co., Ltd.. It covers every address from CC:47:03:00:00:00 to CC:47:03:FF:FF:FF, or 16,777,216 addresses in total. It is also written CC-47-03.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in CC:47:03:00:00:00 that is CC:47:03 — 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 Intercon Systems Co., Ltd. located?

Intercon Systems Co., Ltd. is listed at #915 Hanlim Human Tower,1-40 Geumjeong-dong Gunpo-si Gyeonggi-do KR 435-824 in the IEEE OUI registry entry for CC:47:03. This is the address the organization registered with the IEEE, which may differ from its current operating address.
