Which company owns MAC address prefix CC:FC:B1?

MAC address prefix CC:FC:B1 is registered to Wireless Technology, Inc. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with CC:FC:B1 has a network interface built by Wireless Technology, Inc..

What is the OUI CC:FC:B1?

CC:FC:B1 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Wireless Technology, Inc.. It covers every address from CC:FC:B1:00:00:00 to CC:FC:B1:FF:FF:FF, or 16,777,216 addresses in total. It is also written CC-FC-B1.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in CC:FC:B1:00:00:00 that is CC:FC:B1 — 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 Wireless Technology, Inc. located?

Wireless Technology, Inc. is listed at 2064 Eastman Ave. #113 Ventura CA US 93003-7787 in the IEEE OUI registry entry for CC:FC:B1. This is the address the organization registered with the IEEE, which may differ from its current operating address.
