Which company owns MAC address prefix CC:76:69?

MAC address prefix CC:76:69 is registered to SEETECH in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with CC:76:69 has a network interface built by SEETECH.

What is the OUI CC:76:69?

CC:76:69 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to SEETECH. It covers every address from CC:76:69:00:00:00 to CC:76:69:FF:FF:FF, or 16,777,216 addresses in total. It is also written CC-76-69.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in CC:76:69:00:00:00 that is CC:76:69 — 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 SEETECH located?

SEETECH is listed at 19-15, Seoku-dong Hwasung-si Gyeonggi-do KR 445-170 in the IEEE OUI registry entry for CC:76:69. This is the address the organization registered with the IEEE, which may differ from its current operating address.
