What is the OUI B0:82:AB?

B0:82:AB is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Guangdong Welland Technology Co.,Ltd. It covers every address from B0:82:AB:00:00:00 to B0:82:AB:FF:FF:FF, or 16,777,216 addresses in total. It is also written B0-82-AB.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in B0:82:AB:00:00:00 that is B0:82:AB — 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 Guangdong Welland Technology Co.,Ltd located?

Guangdong Welland Technology Co.,Ltd is listed at No. 7 Minke East Road, Minying Science & Technology Park, Shiqi Zhongshan Guangdong CN 528400 in the IEEE OUI registry entry for B0:82:AB.
