What is the OUI D8:BC:59?

D8:BC:59 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Shenzhen DAPU Microelectronics Co., Ltd. It covers every address from D8:BC:59:00:00:00 to D8:BC:59:FF:FF:FF, or 16,777,216 addresses in total. It is also written D8-BC-59.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in D8:BC:59:00:00:00 that is D8:BC:59 — 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 DAPU Microelectronics Co., Ltd located?

Shenzhen DAPU Microelectronics Co., Ltd is listed at Room B 503, No.2 Building, Tian’an Digital New Town, Huangge Middle Road, Longgang District Shenzhen Guangdong CN 518100 in the IEEE OUI registry entry for D8:BC:59.
