Shenzhen Sande Dacom Electronics Co., Ltd — MAC prefix identification
Summary
- // what this is
- Shenzhen Sande Dacom Electronics is registered to MAC prefix
08:E4:DFand 1 more in the IEEE OUI database. When a device's MAC address begins with08:E4:DF, that block was registered by Shenzhen Sande Dacom Electronics — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- Both assignments are 24-bit prefixes with 24 suffix bits and 16,777,216 possible suffix values each; this is address-space capacity, not a device or shipment count. For each exact prefix, Group bit = 0 and Local bit = 0; changing either bit produces a different prefix. A registry match does not establish deployment, device identity, prevalence, or security state.
About this vendor.
A MAC address beginning with 08:E4:DF or 24:DF:17 matches an IEEE MA-L assignment to Shenzhen Sande Dacom Electronics Co., Ltd; the records do not identify a device type or product for either prefix.
Both assignments are 24-bit prefixes, leaving 24 bits for the remaining address. Each therefore has 16,777,216 possible suffix values. That arithmetic describes the address space available after the prefix; it is not a count of devices, shipments, or addresses observed in use.
For each listed prefix, the first octet has Group bit 0 and Local bit 0. These are fixed for an exact literal prefix match. Changing either bit changes the prefix, rather than describing variation within the assigned prefix. RFC 7042 explains the 48-bit MAC structure and the significance of these bits. A match indicates a registry assignment, not a particular device, deployment, or security state.
- Registry match
- Shenzhen Sande Dacom Electronics Co., Ltd — IEEE MA-L assignments.
- Matching prefixes
08:E4:DFand24:DF:17.- Device identification
- Unknown; the supplied records do not associate either prefix with a device category.
- Interpretation
- Each is a 24-bit prefix with 24 suffix bits; Group and Local bits are both zero in each exact prefix.
