What is the OUI B8:9A:CD?

B8:9A:CD is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to ELITE OPTOELECTRONIC(ASIA)CO.,LTD. It covers every address from B8:9A:CD:00:00:00 to B8:9A:CD:FF:FF:FF, or 16,777,216 addresses in total. It is also written B8-9A-CD.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in B8:9A:CD:00:00:00 that is B8:9A:CD — 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.
