AeroVIronment (AV Inc): MAC prefix identifies a registry assignee
Summary
- // what this is
- AeroVIronment is registered to MAC prefix
00:1A:F9in the IEEE OUI database. When a device's MAC address begins with00:1A:F9, that block was registered by AeroVIronment — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- The MA-L prefix
00:1A:F9is 24 bits, with 24 suffix bits and 16,777,216 possible suffix values. For this literal prefix, the first-byte Group and Local bits are both zero; changing either bit yields a different prefix. The possible suffix values are not a device or shipment count. A match establishes only a registry-prefix match, not a specific device or product.
About this vendor.
A MAC address beginning 00:1A:F9 matches an IEEE MA-L assignment registered to AeroVIronment (AV Inc). The record identifies the assignee; it does not establish which device, product, or current organization is using a matching address.
This 24-bit prefix leaves 24 bits for suffix values, or 16,777,216 possible values. That arithmetic describes the size of the address space under the prefix, not a count of devices or shipments. Check the first three octets for an exact match; a longer address match alone does not identify a specific product.
RFC 7042 explains that the first octet contains the Group and Local bits. For 00, both are zero, so the literal prefix has those bits fixed; changing either bit produces a different prefix. An address capture therefore supports a registry-prefix match, not a conclusion about deployment, traffic prevalence, or safety.
