Acutvista Innovation Co., Ltd. — MAC Prefix Identification
Summary
- // what this is
- Acutvista Innovation is registered to MAC prefix
A0:B6:62in the IEEE OUI database. When a device's MAC address begins withA0:B6:62, that block was registered by Acutvista Innovation — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- A MAC address beginning A0:B6:62 matches this MA-L registry assignment. Both Group and Local bits in this exact prefix are zero; setting either bit changes the prefix. The remaining 24 bits allow 16,777,216 possible suffix values, not an observed device count. Prefix matching does not identify a particular device, product, operator, or security state.
About this vendor.
A MAC address beginning A0:B6:62 matches an IEEE MA-L assignment to Acutvista Innovation Co., Ltd.; the record does not identify a device type or product. This prefix is an assigned registry value, not evidence of which equipment is deployed or who currently operates a captured device.
The 24-bit prefix leaves 24 bits for the remainder of a 48-bit address, allowing 16,777,216 possible suffix values. That arithmetic describes address capacity, not a count of devices, shipments, or addresses observed in use. IEEE's CSV record contains no assignment date.
RFC 7042 explains that the first octet carries Group and Local bits. For this literal prefix, both are fixed at zero; changing either produces a different prefix. A matching address can establish the prefix match, but cannot by itself establish the device, product, operating system, or security state.
