China Electronics Cloud Computing Technology Co., Ltd — MAC prefix identification
Summary
- // what this is
- China Electronics Cloud Computing Technology is registered to MAC prefix
F0:92:58and 1 more in the IEEE OUI database. When a device's MAC address begins withF0:92:58, that block was registered by China Electronics Cloud Computing Technology — the OUI identifies the maker of the network hardware, which is not always the brand on the device.
About this vendor.
A MAC address beginning with F0:92:58 or 5C:23:D6 matches an IEEE MA-L assignment to China Electronics Cloud Computing Technology 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 suffix values. Each therefore has 16,777,216 possible suffix values, a mathematical range rather than a count of devices or shipments. A match establishes only that the address begins with a registered prefix; it does not show deployment, traffic prevalence, current vendor identity, or safety.
For both prefixes, 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, rather than expressing variation within the assigned prefix. RFC 7042 describes the Group and Local bits and the relationship between 48-bit MAC identifiers and their assigned prefixes.
