Ajin Vision Co.,Ltd — MAC prefix identifies an IEEE registry assignment
Summary
- // what this is
- Ajin Vision is registered to MAC prefix
00:1A:3Din the IEEE OUI database. When a device's MAC address begins with00:1A:3D, that block was registered by Ajin Vision — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- A 24-bit match fixes the first-octet Group and Local bits at 0; 24 suffix bits allow 16,777,216 possible values, not a device count. A match indicates an IEEE registry assignment only.
About this vendor.
A MAC address beginning 00:1A:3D matches an IEEE MA-L assignment registered to Ajin Vision Co.,Ltd; the available evidence does not identify a device category or product for that prefix.
This is a 24-bit prefix, leaving 24 bits for suffix values: 16,777,216 possible values. That number describes the address space, not the number of devices made, shipped, or observed. A match establishes the assignment associated with the prefix, not the current identity of an address user or the safety of a device.
The first octet is 00. Its Group bit is 0 and its Local bit is 0, so both are fixed for this literal prefix. RFC 7042 explains the significance of these MAC address bits. Changing either bit changes the prefix and no longer matches this exact assignment. The supplied company record includes a Seoul, KR address indication, supporting country-level identification as South Korea. The IEEE CSV record does not display an assignment date.
