Adapteva, Inc. MAC Prefix 04:4F:8B — Vendor Identified, Device Unknown
Summary
- // what this is
- Adapteva is registered to MAC prefix
04:4F:8Bin the IEEE OUI database. When a device's MAC address begins with04:4F:8B, that block was registered by Adapteva — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- The exact 24-bit prefix has Group bit 0 and Local bit 0 in its first octet (04). It leaves 24 suffix bits, or 16,777,216 possible suffix values; this is not a device or shipment count. A matching address supports the registry assignment only, not product identity, current operator, deployment prevalence, or safety.
About this vendor.
A MAC address beginning with 04:4F:8B matches an IEEE MA-L assignment registered to Adapteva, Inc.; the assignment does not identify a device category or prove which vendor currently operates a device using it.
Adapteva describes itself as a privately held semiconductor company. Its about page says it developed a multicore processor chip for parallel computing, created the Epiphany multicore architecture, and sponsored the Parallella project while designing the Parallella board. These company facts provide context, but no supplied source maps any of those products to this prefix.
The prefix is 24 bits, leaving 24 bits for suffix values: 16,777,216 possible combinations. This is a mathematical range, not a device or shipment count. Its first octet, 04, has Group bit 0 and Local bit 0. For an exact 04:4F:8B match, those bits are fixed; changing either bit produces a different prefix. A captured matching address supports the registry match, not a specific product, operating system, traffic pattern, or security assessment.
RFC 7042 explains the interpretation of these MAC identifier fields.
