Which company owns MAC address prefix C4:36:6C?

MAC address prefix C4:36:6C is registered to LG Innotek in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with C4:36:6C has a network interface built by LG Innotek.

What is the OUI C4:36:6C?

C4:36:6C is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to LG Innotek. It covers every address from C4:36:6C:00:00:00 to C4:36:6C:FF:FF:FF, or 16,777,216 addresses in total. It is also written C4-36-6C.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in C4:36:6C:00:00:00 that is C4:36:6C — 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 LG Innotek located?

LG Innotek is listed at Jangduk-dong 978-1 Gwang-ju Gwangsan-gu KR 506-731 in the IEEE OUI registry entry for C4:36:6C. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does LG Innotek own?

LG Innotek holds 50 OUI prefixes in the IEEE registry, of which C4:36:6C is one. A device made by LG Innotek could carry a MAC address from any of them.
