What is the OUI B0:41:6F?

B0:41:6F is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Shenzhen Maxtang Computer Co.,Ltd. It covers every address from B0:41:6F:00:00:00 to B0:41:6F:FF:FF:FF, or 16,777,216 addresses in total. It is also written B0-41-6F.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in B0:41:6F:00:00:00 that is B0:41:6F — 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 Maxtang Computer Co.,Ltd located?
