Which company owns MAC address prefix FC:DC:4A?

MAC address prefix FC:DC:4A is registered to G-Wearables Corp. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with FC:DC:4A has a network interface built by G-Wearables Corp..

What is the OUI FC:DC:4A?

FC:DC:4A is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to G-Wearables Corp.. It covers every address from FC:DC:4A:00:00:00 to FC:DC:4A:FF:FF:FF, or 16,777,216 addresses in total. It is also written FC-DC-4A.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in FC:DC:4A:00:00:00 that is FC:DC:4A — 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 G-Wearables Corp. located?

G-Wearables Corp. is listed at 901, S&CTBuilding, No.9 Zhongguancun South Avenue Beijing Beijing CN 100081 in the IEEE OUI registry entry for FC:DC:4A. This is the address the organization registered with the IEEE, which may differ from its current operating address.
