Which company owns MAC address prefix DC:CE:BC?

MAC address prefix DC:CE:BC is registered to Shenzhen JSR Technology Co.,Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with DC:CE:BC has a network interface built by Shenzhen JSR Technology Co.,Ltd..

What is the OUI DC:CE:BC?

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

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in DC:CE:BC:00:00:00 that is DC:CE:BC — 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 JSR Technology Co.,Ltd. located?

Shenzhen JSR Technology Co.,Ltd. is listed at 2-3F,E building,Yu Jianfeng science and industry park Shenzhen City Guangdong CN 518109 in the IEEE OUI registry entry for DC:CE:BC. This is the address the organization registered with the IEEE, which may differ from its current operating address.
