Shenzhen Excelsecu Data Technology Co.,Ltd — device identity unknown
Summary
- // what this is
- Shenzhen Excelsecu Data Technology is registered to MAC prefix
C4:D4:96and 1 more in the IEEE OUI database. When a device's MAC address begins withC4:D4:96, that block was registered by Shenzhen Excelsecu Data Technology — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- Each 24-bit prefix has 24 suffix bits and 16,777,216 possible suffix values. In both prefixes, the first-byte Group and Local bits are zero. A literal prefix match identifies an IEEE registry assignment, not a device or deployment.
About this vendor.
A MAC address beginning with C4:D4:96 or 84:1B:38 matches an IEEE MA-L assignment to Shenzhen Excelsecu Data Technology Co.,Ltd; the assignment does not identify a particular device or product. The supplied records do not establish what device category, if any, uses either prefix. They list China as the registrant country, but do not provide assignment dates.
Each prefix is 24 bits long, leaving 24 suffix bits and 16,777,216 possible suffix values per prefix. That is a mathematical address-space size, not a count of devices, shipments, or observed addresses. In both prefixes the first-byte Group and Local bits are zero. Under RFC 7042, those bits distinguish group and locally administered addressing; changing either bit produces a different prefix. A captured address matching the literal prefix supports an assignment match only.
It does not establish deployment, traffic prevalence, current vendor identity, or security status.
