DC:81:3Dand 1 more in the IEEE OUI database. When a device's MAC address begins withDC:81:3D, that block was registered by Shanghai Xiangcheng Communication Technology — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note

About this vendor.
A MAC address beginning with DC:81:3D or 58:BD:35 matches an IEEE MA-L assignment to SHANGHAI XIANGCHENG COMMUNICATION TECHNOLOGY CO., LTD. The assignment does not identify a specific device or prove that a captured address is deployed by the company.
KOZEN’s company profile identifies Shanghai Xiangcheng Communication Technology Co., Ltd. as the parent of its independent brand and describes electronic payment and smart POS solutions, including customized hardware design and software consulting. Its listed categories include payment POS, desktop POS, handheld printers, and industrial PDAs. The profile does not map those products to either prefix.
Each listed prefix is 24 bits long, leaving 24 suffix bits and 16,777,216 possible suffix values per prefix. The Group bit and Local bit in the first byte are both 0 for each exact prefix. RFC 7042 explains that the Group bit distinguishes group from individual identifiers and the Local bit indicates local administration; changing either bit changes the prefix match. Possible suffix values are not a count of devices or shipments.
