Which company owns MAC address prefix 30:78:C2?

MAC address prefix 30:78:C2 is registered to Innowireless / QUCELL Networks in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 30:78:C2 has a network interface built by Innowireless / QUCELL Networks.

What is the OUI 30:78:C2?

30:78:C2 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Innowireless / QUCELL Networks. It covers every address from 30:78:C2:00:00:00 to 30:78:C2:FF:FF:FF, or 16,777,216 addresses in total. It is also written 30-78-C2.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 30:78:C2:00:00:00 that is 30:78:C2 — 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 Innowireless / QUCELL Networks located?

Innowireless / QUCELL Networks is listed at Innowireless Bldg. 190 Seohyeon-ro Bundang-gu, Seongnam-si Gyeonggi-do KR 13590 in the IEEE OUI registry entry for 30:78:C2. This is the address the organization registered with the IEEE, which may differ from its current operating address.
