Recogni Inc MAC prefixes: device identity is Unknown
Summary
- // what this is
- Recogni is registered to MAC prefix
34:AF:A3and 1 more in the IEEE OUI database. When a device's MAC address begins with34:AF:A3, that block was registered by Recogni — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- A MAC prefix match indicates a registry assignment; it does not establish deployment, traffic prevalence, device count, product use, or security state. Each 24-bit prefix leaves 24 suffix bits (16,777,216 possible suffix values); these are address possibilities, not an observed device or shipment count. Both prefixes have Group bit 0 and Local bit 0 in their first byte, as fixed by the exact prefix. Changing either bit produces a different prefix.
About this vendor.
A MAC address beginning with 34:AF:A3 or 38:47:F2 identifies an IEEE MA-L assignment to Recogni Inc; the supplied evidence does not identify a device category or product using either prefix. A prefix match therefore supports the registry attribution, not a particular device, operating system, or security status.
Each assignment covers a 24-bit prefix, leaving 24 bits for the suffix and 16,777,216 possible suffix values per prefix. These are possible address values, not a count of devices, shipments, or observed network activity.
Both listed prefixes have the Group and Local bits set to zero. RFC 7042 identifies these as special bits in the initial octet of MAC addresses and states that IEEE assigns OUIs and longer MAC prefixes with the Local bit zero and the Group bit unspecified. The IEEE CSV records shown contain no assignment dates.
- Registry identity
- Recogni Inc is the organization named for both MA-L assignments.
- Matching prefixes
34:AF:A3and38:47:F2.- Device or product identification
- Unknown from the supplied evidence.
- Interpretation
- A match establishes the listed prefix assignment, not deployment, prevalence, product use, or security status.

- Technical interpretation
- The first-byte Group and Local bits are both zero for these prefixes; changing either bit changes the matched prefix. [Confirmed] — https://www.rfc-editor.org/rfc/rfc7042.txt
