Which company owns MAC address prefix 70:8C:BB?

MAC address prefix 70:8C:BB is registered to MIMODISPLAYKOREA in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 70:8C:BB has a network interface built by MIMODISPLAYKOREA.

What is the OUI 70:8C:BB?

70:8C:BB is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to MIMODISPLAYKOREA. It covers every address from 70:8C:BB:00:00:00 to 70:8C:BB:FF:FF:FF, or 16,777,216 addresses in total. It is also written 70-8C-BB.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 70:8C:BB:00:00:00 that is 70:8C:BB — 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 MIMODISPLAYKOREA located?

MIMODISPLAYKOREA is listed at #812, 19, Ojeongongeop-gil Uiwang-si Gyeonggi-do KR 16072 in the IEEE OUI registry entry for 70:8C:BB. This is the address the organization registered with the IEEE, which may differ from its current operating address.
