Tuya Smart Inc. — 42 个 OUI 前缀
下面列出 Wireshark 数据文件中以 TuyaSmart 为简称的地址块。它们指向地址块的登记机构，不一定是成品设备的品牌。代工网卡、第三方无线模块、企业并购和历史登记名称都可能造成品牌不一致。
表格标注每条记录的前缀长度：MA-L 为 24 位、MA-M 为 28 位、MA-S 为 36 位。范围首尾表示该登记块的边界，不保证范围内的每个地址已用于实际设备。输入完整的 12 位十六进制 MAC，可让查询优先匹配更长的前缀。
该结果不能确定设备型号、机主或物理位置，也不能证明设备身份。随机地址、本地管理地址和人工修改的地址不能可靠地用于厂商识别。资产盘点时，请结合交换机 MAC 表、DHCP 租约和设备序列号交叉检查。
