Which company owns MAC address prefix C8:9C:13?

MAC address prefix C8:9C:13 is registered to Inspiremobile in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with C8:9C:13 has a network interface built by Inspiremobile.

What is the OUI C8:9C:13?

C8:9C:13 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Inspiremobile. It covers every address from C8:9C:13:00:00:00 to C8:9C:13:FF:FF:FF, or 16,777,216 addresses in total. It is also written C8-9C-13.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in C8:9C:13:00:00:00 that is C8:9C:13 — 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 Inspiremobile located?

Inspiremobile is listed at Rm1412, Daeryung Techno-Town, 15th, 401 , Simin-daero, Dongan-gu Anyang-si Gyeonggi-do KR 14057 in the IEEE OUI registry entry for C8:9C:13. This is the address the organization registered with the IEEE, which may differ from its current operating address.
