Shenzhen Yinwang Intelligent Technologies Co.,Ltd. MAC prefixes: device identity Unknown
Summary
- // what this is
- Shenzhen Yinwang Intelligent Technologies is registered to MAC prefix
10:91:66and 1 more in the IEEE OUI database. When a device's MAC address begins with10:91:66, that block was registered by Shenzhen Yinwang Intelligent Technologies — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- Both listed prefixes are 24 bits long, leaving 24 suffix bits (16,777,216 possible suffix values) apiece. Their first-octet Group and Local bits are both zero. The suffix capacity is not an observed device or shipment count; a match identifies only the registry assignment.
About this vendor.
A MAC address beginning with 10:91:66 or B8:CC:38 identifies an IEEE MA-L assignment to Shenzhen Yinwang Intelligent Technologies Co.,Ltd.; the supplied evidence does not identify a device category or product using either prefix. The two assignments are separate entries, and the company name appears with a minor punctuation variation in the registry records.
Both prefixes are 24 bits long, leaving 24 bits for suffix values: 16,777,216 possible values per prefix. In each prefix’s first octet, the Group bit and Local bit are both zero. These fixed values describe the exact listed prefixes; changing either bit produces a different prefix. The possible suffix values are address-space capacity, not a count of devices or shipments.
A matching prefix supports identification of the registry assignment only. It does not establish the particular device, its deployment, traffic prevalence, present vendor identity, or security state. RFC 7042 explains that 48-bit MAC identifiers can use a three-octet OUI followed by three additional octets, and describes the Group and Local bits.
