AirVine Scientific, Inc. — registered MAC prefix
Summary
- // what this is
- AirVine Scientific is registered to MAC prefix
A4:F9:E4in the IEEE OUI database. When a device's MAC address begins withA4:F9:E4, that block was registered by AirVine Scientific — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- A 48-bit address beginning A4:F9:E4 matches the registered 24-bit MA-L prefix, with 24 remaining suffix bits. The first-byte Group and Local bits are both 0 for this exact prefix. A match establishes registry assignment only; possible suffix values do not indicate device or shipment counts.
About this vendor.
A MAC address beginning A4:F9:E4 matches an IEEE MA-L assignment registered to AirVine Scientific, Inc.; the record does not identify a device type or product. This identifies the registry assignment associated with the address prefix, not the device’s maker, current owner, deployment, or security status.
The prefix is 24 bits long, leaving 24 bits for suffix values: 16,777,216 possible values. That is a count of possible suffixes, not a count of devices or shipments. The captured address can establish a match to this assignment, but cannot identify a specific product.
The first octet A4 has Group bit 0 and Local bit 0. For this exact prefix, those bits are fixed; changing either bit produces a different prefix. RFC 7042 explains the significance of these bits and the structure of 48-bit MAC identifiers. The IEEE CSV record provides no assignment date.
