Add-On Technology Co., LTD. — device identification unknown
Summary
- // what this is
- Add-On Technology is registered to MAC prefix
00:13:85in the IEEE OUI database. When a device's MAC address begins with00:13:85, that block was registered by Add-On Technology — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- A prefix match identifies a registry assignment and cannot establish a particular device, product, current deployment, or security state.
About this vendor.
A MAC address beginning 00:13:85 identifies an IEEE MA-L assignment registered to Add-On Technology Co., LTD.; the record does not identify a device category or product. This prefix alone cannot establish which device sent a captured address or whether it is currently deployed by the registrant.
The assignment is 24 bits long, leaving 24 bits for suffix values: 16,777,216 possible values within that prefix. This is a mathematical range, not a count of devices or shipments. For this exact prefix, the first octet 00 has Group bit 0 and Local bit 0. A matching address must share all 24 prefix bits; changing either bit creates a different prefix. RFC 7042 describes the Group and Local bits and MAC prefix structure.
The IEEE record gives Taipei, TW, supporting Taiwan as the country indication. Assignment dates are unavailable in these IEEE CSV records.
