Which company owns MAC address prefix B8:C1:A2?

MAC address prefix B8:C1:A2 is registered to Dragon Path Technologies Co., Limited in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with B8:C1:A2 has a network interface built by Dragon Path Technologies Co., Limited.

What is the OUI B8:C1:A2?

B8:C1:A2 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Dragon Path Technologies Co., Limited. It covers every address from B8:C1:A2:00:00:00 to B8:C1:A2:FF:FF:FF, or 16,777,216 addresses in total. It is also written B8-C1-A2.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in B8:C1:A2:00:00:00 that is B8:C1:A2 — 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 Dragon Path Technologies Co., Limited located?

Dragon Path Technologies Co., Limited is listed at 12/F., San Toi Building, Central Hong Kong HK in the IEEE OUI registry entry for B8:C1:A2. This is the address the organization registered with the IEEE, which may differ from its current operating address.
