Which company owns MAC address prefix 90:6D:05?

MAC address prefix 90:6D:05 is registered to BXB ELECTRONICS CO., LTD in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 90:6D:05 has a network interface built by BXB ELECTRONICS CO., LTD.

What is the OUI 90:6D:05?

90:6D:05 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to BXB ELECTRONICS CO., LTD. It covers every address from 90:6D:05:00:00:00 to 90:6D:05:FF:FF:FF, or 16,777,216 addresses in total. It is also written 90-6D-05.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 90:6D:05:00:00:00 that is 90:6D:05 — 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 BXB ELECTRONICS CO., LTD located?

BXB ELECTRONICS CO., LTD is listed at 6F.-1, NO.288-5, Xinya Rd., Qianzhen Dist. Kaohsiung TW 80673 in the IEEE OUI registry entry for 90:6D:05. This is the address the organization registered with the IEEE, which may differ from its current operating address.
