Which company owns MAC address prefix 84:30:CE?

MAC address prefix 84:30:CE is registered to Shenzhen Jaguar Microsystems Co., Ltd in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 84:30:CE has a network interface built by Shenzhen Jaguar Microsystems Co., Ltd.

What is the OUI 84:30:CE?

84:30:CE is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Shenzhen Jaguar Microsystems Co., Ltd. It covers every address from 84:30:CE:00:00:00 to 84:30:CE:FF:FF:FF, or 16,777,216 addresses in total. It is also written 84-30-CE.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 84:30:CE:00:00:00 that is 84:30:CE — 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 Jaguar Microsystems Co., Ltd located?

Shenzhen Jaguar Microsystems Co., Ltd is listed at 1101 Hanjing Financial Center, 9968 Shennan Blvd, Nanshan, Shenzhen Shenzhen CN 518000 in the IEEE OUI registry entry for 84:30:CE. This is the address the organization registered with the IEEE, which may differ from its current operating address.
