Xiamen Yeastar Digital Technology Co.,Ltd MAC prefix identification
Summary
- // what this is
- Xiamen Yeastar Digital Technology is registered to MAC prefix
80:C2:F0and 1 more in the IEEE OUI database. When a device's MAC address begins with80:C2:F0, that block was registered by Xiamen Yeastar Digital Technology — 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, leaving 24 suffix bits and 16,777,216 possible suffix values per prefix; this is capacity, not a device or shipment count. For both exact prefixes, the first-octet Group and Local bits are 0. Toggling either bit changes the prefix. An exact prefix match indicates a registry assignment and does not identify a device, deployment, operator, or security state. RFC 7042 discusses 48-bit MAC identifiers and these bits' significance.
About this vendor.
A MAC address beginning 80:C2:F0 or F4:B5:49 matches an IEEE MA-L assignment to Xiamen Yeastar Digital Technology Co.,Ltd. The registry record identifies the assignee; it does not establish the device type, product, or who operates a device using a matching address.
Both are 24-bit prefixes, leaving 24 bits for suffix values: 16,777,216 possible values under each assignment. This is address-space capacity, not a count of devices or shipments. A captured address can establish a prefix match, but does not by itself establish deployment or prevalence.
For each prefix, the first octet has Group bit 0 and Local bit 0. These bits are fixed for an exact prefix match. Changing either bit changes the prefix, so the matching assignment does not cover addresses formed by toggling those bits. RFC 7042 describes the structure and bit significance of 48-bit MAC identifiers.
