Adaptive Instruments — MAC prefix identifies a registry assignment; device type Unknown
Summary
- // what this is
- Adaptive Instruments is registered to MAC prefix
00:0F:B9in the IEEE OUI database. When a device's MAC address begins with00:0F:B9, that block was registered by Adaptive Instruments — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- An exact match identifies the MA-L registry assignment. The first-octet Group and Local bits are both 0; changing either bit yields a different prefix. The 24-bit suffix allows 16,777,216 possible values, not a device or shipment count. A prefix match does not identify a particular device or establish deployment or security state.
About this vendor.
A MAC address beginning 00:0F:B9 matches the IEEE MA-L assignment to Adaptive Instruments. The supplied evidence does not identify a device category or connect this prefix to a particular product, so the device type is Unknown.
This is one 24-bit prefix, leaving 24 bits for suffix values. The 24-bit suffix allows 2^24 = 16,777,216 possible values; this is an address-space count, not a count of devices, shipments, or observed traffic. The first octet 00 has Group bit 0 and Local bit 0. An exact literal prefix match therefore has both bits clear. Changing either bit produces a different prefix, not a variation within this fixed assignment.
A matching address supports identifying the registered prefix only. It does not establish a specific device, deployment, current vendor identity, or security state. RFC 7042 describes 48-bit MAC identifiers as an assigned initial prefix followed by additional bits, and explains the Group and Local bit significance.
