Which company owns MAC address prefix C0:2B:56?

MAC address prefix C0:2B:56 is registered to CANDID OPTRONIX PRIVATE LIMITED in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with C0:2B:56 has a network interface built by CANDID OPTRONIX PRIVATE LIMITED.

What is the OUI C0:2B:56?

C0:2B:56 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to CANDID OPTRONIX PRIVATE LIMITED. It covers every address from C0:2B:56:00:00:00 to C0:2B:56:FF:FF:FF, or 16,777,216 addresses in total. It is also written C0-2B-56.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in C0:2B:56:00:00:00 that is C0:2B:56 — 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 CANDID OPTRONIX PRIVATE LIMITED located?

CANDID OPTRONIX PRIVATE LIMITED is listed at C-1 to C-6, C-65 to C-71, SIGADDI GROWTH CENTRE, VILLAGE KISHAN DEVPUR, Kotdwara, Pauri Garhwal Kotdwara Uttarakhand IN 246149 in the IEEE OUI registry entry for C0:2B:56. This is the address the organization registered with the IEEE, which may differ from its current operating address.
