Which company owns MAC address prefix 70:C7:6F?

MAC address prefix 70:C7:6F is registered to INNO S in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 70:C7:6F has a network interface built by INNO S.

What is the OUI 70:C7:6F?

70:C7:6F is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to INNO S. It covers every address from 70:C7:6F:00:00:00 to 70:C7:6F:FF:FF:FF, or 16,777,216 addresses in total. It is also written 70-C7-6F.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 70:C7:6F:00:00:00 that is 70:C7:6F — 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 INNO S located?

INNO S is listed at 215beon-gil, 119 Guri-si Gyeonggi-do KR 471-060 in the IEEE OUI registry entry for 70:C7:6F. This is the address the organization registered with the IEEE, which may differ from its current operating address.

INNO S

MAC address prefix 70:C7:6F is registered to INNO S in the IEEE OUI registry. Any device whose MAC address begins with 70:C7:6F has a network interface built by INNO S. This prefix (the OUI, or Organizationally Unique Identifier) is assigned by the IEEE and is the first three octets of the address — it covers every MAC from 70:C7:6F:00:00:00 to 70:C7:6F:FF:FF:FF.
