Which company owns MAC address prefix DC:4B:FE?

MAC address prefix DC:4B:FE is registered to Shenzhen Belon Technology CO.,LTD in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with DC:4B:FE has a network interface built by Shenzhen Belon Technology CO.,LTD.

What is the OUI DC:4B:FE?

DC:4B:FE is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Shenzhen Belon Technology CO.,LTD. It covers every address from DC:4B:FE:00:00:00 to DC:4B:FE:FF:FF:FF, or 16,777,216 addresses in total. It is also written DC-4B-FE.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in DC:4B:FE:00:00:00 that is DC:4B:FE — 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 Shenzhen Belon Technology CO.,LTD located?

Shenzhen Belon Technology CO.,LTD is listed at Tsinghua Information Shenzhen Guangdong CN 518052 in the IEEE OUI registry entry for DC:4B:FE. This is the address the organization registered with the IEEE, which may differ from its current operating address.
