99IOT Shenzhen co.,ltd — MAC prefix identifies a registry assignment; device type unknown
Summary
- // what this is
- 99IOT Shenzhen is registered to MAC prefix
70:1D:08in the IEEE OUI database. When a device's MAC address begins with70:1D:08, that block was registered by 99IOT Shenzhen — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- A 24-bit
70:1D:08prefix match identifies the IEEE registry assignment only. The first-byte Group and Local bits are fixed at 0; 24 suffix bits allow 16,777,216 possible values, not a device or shipment count. RFC 7042 describes the Group and Local bit semantics.
About this vendor.
A MAC address beginning 70:1D:08 matches an IEEE MA-L assignment to 99IOT Shenzhen co.,ltd; the supplied records do not identify a device category or product for this prefix. The assignment names a registrant, not a verified device maker, current legal identity, or deployed device.
The prefix is 24 bits of a 48-bit MAC address, leaving 24 bits for suffix values. Its Group and Local bits are both zero. RFC 7042 explains that these bits indicate group and local addressing semantics; matching this exact prefix fixes both bits. Changing either bit changes the prefix and is not a variation within this assignment. The 16,777,216 possible suffix values are a mathematical address space, not a count of devices or shipments.
For practical identification, a matching address supports only that its first 24 bits equal the registered prefix. It does not establish what equipment used the address, whether it was actually deployed, or its safety. Assignment dates are unavailable in these IEEE CSV records.
