Which company owns MAC address prefix B0:28:5B?

MAC address prefix B0:28:5B is registered to JUHUA Technology Inc. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with B0:28:5B has a network interface built by JUHUA Technology Inc..

What is the OUI B0:28:5B?

B0:28:5B is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to JUHUA Technology Inc.. It covers every address from B0:28:5B:00:00:00 to B0:28:5B:FF:FF:FF, or 16,777,216 addresses in total. It is also written B0-28-5B.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in B0:28:5B:00:00:00 that is B0:28:5B — 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 JUHUA Technology Inc. located?

JUHUA Technology Inc. is listed at No.8,Yanbao Block,Hutian Road,Pingdi Street,Longgang District Shenzhen City Guangdong Province CN 518117 in the IEEE OUI registry entry for B0:28:5B.
