What is the OUI 5C:8E:8B?

5C:8E:8B is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Shenzhen Linghai Electronics Co.,Ltd. It covers every address from 5C:8E:8B:00:00:00 to 5C:8E:8B:FF:FF:FF, or 16,777,216 addresses in total. It is also written 5C-8E-8B.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 5C:8E:8B:00:00:00 that is 5C:8E:8B — 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 Linghai Electronics Co.,Ltd located?
