Which company owns MAC address prefix B4:50:62?

MAC address prefix B4:50:62 is registered to EmBestor Technology Inc. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with B4:50:62 has a network interface built by EmBestor Technology Inc..

What is the OUI B4:50:62?

B4:50:62 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to EmBestor Technology Inc.. It covers every address from B4:50:62:00:00:00 to B4:50:62:FF:FF:FF, or 16,777,216 addresses in total. It is also written B4-50-62.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in B4:50:62:00:00:00 that is B4:50:62 — 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 EmBestor Technology Inc. located?

EmBestor Technology Inc. is listed at 7F, No.1, Chin-Shan 8th St Hsin-Chu, Taiwan TW 300 in the IEEE OUI registry entry for B4:50:62. This is the address the organization registered with the IEEE, which may differ from its current operating address.
