Which company owns MAC address prefix A8:5B:B0?

MAC address prefix A8:5B:B0 is registered to Shenzhen Dehoo Technology Co.,Ltd in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with A8:5B:B0 has a network interface built by Shenzhen Dehoo Technology Co.,Ltd.

What is the OUI A8:5B:B0?

A8:5B:B0 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Shenzhen Dehoo Technology Co.,Ltd. It covers every address from A8:5B:B0:00:00:00 to A8:5B:B0:FF:FF:FF, or 16,777,216 addresses in total. It is also written A8-5B-B0.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in A8:5B:B0:00:00:00 that is A8:5B:B0 — 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 Dehoo Technology Co.,Ltd located?

Shenzhen Dehoo Technology Co.,Ltd is listed at 5C,Tianzhan Building Tianan Cyberpark, ShenZhen Guang Dong CN 518040 in the IEEE OUI registry entry for A8:5B:B0. This is the address the organization registered with the IEEE, which may differ from its current operating address.
