Which company owns MAC address prefix C8:29:2A?

MAC address prefix C8:29:2A is registered to Barun Electronics in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with C8:29:2A has a network interface built by Barun Electronics.

What is the OUI C8:29:2A?

C8:29:2A is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Barun Electronics. It covers every address from C8:29:2A:00:00:00 to C8:29:2A:FF:FF:FF, or 16,777,216 addresses in total. It is also written C8-29-2A.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in C8:29:2A:00:00:00 that is C8:29:2A — 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 Barun Electronics located?

Barun Electronics is listed at 869, Jangji-ri, Dongtan-myeon Hwaseong-si Gyeonggi-do KR 445812 in the IEEE OUI registry entry for C8:29:2A. This is the address the organization registered with the IEEE, which may differ from its current operating address.
