Which company owns MAC address prefix CC:50:76?

MAC address prefix CC:50:76 is registered to Ocom Communications, Inc. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with CC:50:76 has a network interface built by Ocom Communications, Inc..

What is the OUI CC:50:76?

CC:50:76 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Ocom Communications, Inc.. It covers every address from CC:50:76:00:00:00 to CC:50:76:FF:FF:FF, or 16,777,216 addresses in total. It is also written CC-50-76.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in CC:50:76:00:00:00 that is CC:50:76 — 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 Ocom Communications, Inc. located?

Ocom Communications, Inc. is listed at 13F-6, No. 1, Bao Sheng Rd., Yong Ho City TW 234 in the IEEE OUI registry entry for CC:50:76. This is the address the organization registered with the IEEE, which may differ from its current operating address.
