ACTIVIO Inc. MAC Prefix: Device Identity Unknown
Summary
- // what this is
- Activio is registered to MAC prefix
A4:5E:5Ain the IEEE OUI database. When a device's MAC address begins withA4:5E:5A, that block was registered by Activio — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- A matching address establishes a match to this registry assignment only. The 24-bit suffix space contains 16,777,216 possible values; this is not a device or shipment count. The Group and Local bits for this literal prefix are both zero and fixed.
About this vendor.
A MAC address beginning A4:5E:5A matches an IEEE MA-L assignment to ACTIVIO Inc. The supplied registry record does not identify a device, product, or deployment, so the device or vendor represented by a captured address is unknown. The record indicates Japan, but gives no assignment date.
This is a 24-bit prefix: a match requires the first three octets to equal A4:5E:5A. Its first octet is A4; the Group bit and Local bit are both zero. Those bits are fixed for this exact prefix. Changing either bit produces a different prefix, not another address within this assignment.
The remaining 24 bits allow 16,777,216 possible suffix values, not a count of devices, shipments, or observed addresses. A match supports identifying the registry assignment only; it does not establish a particular device, product, current vendor identity, or security state. RFC 7042 describes the relationship between MAC identifiers and assigned prefixes.
