Which company owns MAC address prefix CC:C6:2B?

MAC address prefix CC:C6:2B is registered to Tri-Systems Corporation in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with CC:C6:2B has a network interface built by Tri-Systems Corporation.

What is the OUI CC:C6:2B?

CC:C6:2B is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Tri-Systems Corporation. It covers every address from CC:C6:2B:00:00:00 to CC:C6:2B:FF:FF:FF, or 16,777,216 addresses in total. It is also written CC-C6-2B.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in CC:C6:2B:00:00:00 that is CC:C6:2B — 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 Tri-Systems Corporation located?

Tri-Systems Corporation is listed at 3-27-8 TRS Building 3F Hachioji Tokyo JP 192-0904 in the IEEE OUI registry entry for CC:C6:2B. This is the address the organization registered with the IEEE, which may differ from its current operating address.
