Which company owns MAC address prefix 28:0C:2D?

MAC address prefix 28:0C:2D is registered to QUALVISION TECHNOLOGY CO.,LTD in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 28:0C:2D has a network interface built by QUALVISION TECHNOLOGY CO.,LTD.

What is the OUI 28:0C:2D?

28:0C:2D is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to QUALVISION TECHNOLOGY CO.,LTD. It covers every address from 28:0C:2D:00:00:00 to 28:0C:2D:FF:FF:FF, or 16,777,216 addresses in total. It is also written 28-0C-2D.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 28:0C:2D:00:00:00 that is 28:0C:2D — 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 QUALVISION TECHNOLOGY CO.,LTD located?

QUALVISION TECHNOLOGY CO.,LTD is listed at 2F-5F, Bldg B, No.37, Zhenxing Road Liyuhe Industrial Park, Loucun, Gongming, shenzhen, China, 518107 China shenzhen CN 518107 in the IEEE OUI registry entry for 28:0C:2D. This is the address the organization registered with the IEEE, which may differ from its current operating address.
