A MAC address beginning 04:50:DA or 74:AC:5F matches an IEEE MA-L assignment to Qiku Internet Network Scientific (Shenzhen) Co., Ltd. The available evidence does not identify a device category for either exact prefix. A match establishes the registry assignment, not a particular product, operating system, current legal identity, or security state. [https://standards-oui.ieee.org/oui/oui.csv]

A Qualcomm announcement describes QiKu as a joint venture between Qihu and Coolpad and says the company offered smartphones, the 360 Operating System, and connected devices. It also reports a license for specified 3G and 4G subscriber units for use in China. These company-level details do not map any product or device category to the listed prefixes.

Each assignment is a 24-bit prefix, leaving 24 bits for possible suffix values: 16,777,216 per prefix. This is a mathematical address-space size, not a count of devices or shipments. The first byte of each prefix has Group bit 0 and Local bit 0. RFC 7042 explains these bits: the assignment fixes them for an exact literal prefix match; changing either bit produces a different prefix. [https://www.rfc-editor.org/rfc/rfc7042.txt]
