What is the OUI B0:90:74?

B0:90:74 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Fulan Electronics Limited. It covers every address from B0:90:74:00:00:00 to B0:90:74:FF:FF:FF, or 16,777,216 addresses in total. It is also written B0-90-74.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in B0:90:74:00:00:00 that is B0:90:74 — 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 Fulan Electronics Limited located?

Fulan Electronics Limited is listed at Flat B&C,3/F,A1 Block, Gaoxin Cyber-Tech Zone,Nanshan Shenzhen Guangdong CN 518057 in the IEEE OUI registry entry for B0:90:74. This is the address the organization registered with the IEEE, which may differ from its current operating address.
