AISIN CORPORATION MAC Prefix 00:1E:43: Vendor Assignment
Summary
- // what this is
- Aisin is registered to MAC prefix
00:1E:43in the IEEE OUI database. When a device's MAC address begins with00:1E:43, that block was registered by Aisin — 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 match fixes the first-octet Group and Local bits at zero; 24 suffix bits permit 16,777,216 possible values, which is not a device or shipment count. A match indicates registry assignment only.
About this vendor.
A MAC address beginning 00:1E:43 matches an IEEE MA-L assignment to AISIN CORPORATION; the prefix alone does not identify a particular device or device category. The record indicates Japan (JP), but provides no product or device mapping for this prefix.
This 24-bit prefix fixes the first octet as 00: its Group bit and Local bit are both zero. A captured address matching all 24 prefix bits has 24 remaining bits, allowing 16,777,216 possible suffix values. That number describes the size of the suffix space, not the number of devices made, shipped, or observed.
For identification, compare the first three octets with 00:1E:43. A match supports the registry-assignment statement; it does not establish the address's deployment, traffic prevalence, current vendor identity, or security status. RFC 7042 describes the relationship between MAC identifiers and assigned prefixes, including these bit conventions.
