SystemX Co.,Ltd. MAC Prefixes: Device Type Unknown
Summary
- // what this is
- SystemX is registered to MAC prefix
CC:A1:50and 1 more in the IEEE OUI database. When a device's MAC address begins withCC:A1:50, that block was registered by SystemX — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- A matching address identifies an IEEE MA-L registry assignment. Both prefixes are 24 bits, leaving 24 suffix bits each (16,777,216 possible values per prefix). Their first-byte Group and Local bits are both zero; changing either bit produces a different prefix. Possible suffix values are not a device or shipment count. A prefix match does not identify a device category or prove deployment.
About this vendor.
A MAC address beginning with CC:A1:50 or 88:9A:FF matches an IEEE MA-L assignment registered to SystemX Co.,Ltd. The supplied records do not identify a device category, so the prefix alone cannot say what device is present. A match establishes the registered prefix only; it does not establish deployment, traffic prevalence, current vendor identity, or safety.
Both assignments are 24-bit prefixes in 48-bit MAC identifiers, leaving 24 suffix bits and 16,777,216 possible suffix values per prefix. These are possible address suffixes, not a count of devices or shipments. For both prefixes, the first-byte Group and Local bits are zero. Changing either bit produces a different prefix; those bit changes are not variations within either fixed assignment. RFC 7042 describes the 48-bit identifier structure and these bits.
