Ablelink Electronics Ltd MAC prefix 84:4F:03: device identification unknown
Summary
- // what this is
- Ablelink Electronics is registered to MAC prefix
84:4F:03in the IEEE OUI database. When a device's MAC address begins with84:4F:03, that block was registered by Ablelink Electronics — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- A match identifies the IEEE registry assignment only; it does not establish a device, product, deployment, or device count. For the exact prefix 84:4F:03, Group bit = 0 and Local bit = 0; either bit changing alters the literal prefix match. The 24-bit suffix allows 16,777,216 possible values, not an observed device or shipment count.
About this vendor.
A MAC address beginning with 84:4F:03 matches an IEEE MA-L assignment to Ablelink Electronics Ltd; the supplied records do not identify a device or product using it. A match supports identifying the registry assignment only, not who deployed the address or what device it belongs to.
This is a 24-bit prefix, leaving 24 bits for suffix values: 16,777,216 possible values. That is a mathematical range, not a count of devices or shipments. RFC 7042 explains that a 48-bit MAC identifier can use a three-octet OUI followed by three additional octets, and assigns meaning to the Group and Local bits in the first octet.
For 84:4F:03, the first-octet Group bit and Local bit are both zero. Those values are fixed for an exact literal prefix match. Changing either bit changes the prefix, so interpreting a modified first octet as variation within this assignment would be incorrect. The available IEEE CSV row supplies no assignment date.
