00:18:92 MAC Prefix — Device Identity Unknown
Summary
- // what this is
- ads-tec is registered to MAC prefix
00:18:92in the IEEE OUI database. When a device's MAC address begins with00:18:92, that block was registered by ads-tec — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- A literal 00:18:92 match fixes the first octet's Group and Local bits at zero. The 24-bit matching boundary leaves 24 suffix bits, or 16,777,216 possible suffix values; this does not indicate an actual device or shipment count. A match identifies the registry assignment only.
About this vendor.
A MAC address beginning with 00:18:92 is assigned to ads-tec GmbH in the IEEE MA-L registry; the supplied evidence does not identify a device category or product using this prefix. The record gives an unambiguous country indication of Germany (DE), but does not establish current vendor identity or deployment of any address bearing the prefix.
The 24-bit prefix fixes the first three octets. In its first octet, 00, the Group bit (01) and Local bit (02) are both zero. A literal match to 00:18:92 therefore has those bit values fixed; changing either bit produces a different prefix. The remaining 24 bits allow 16,777,216 possible suffix values. That is an address-space count, not a count of devices, shipments, or observed addresses.
A captured address that matches this prefix supports identifying the registry assignment only. It does not establish a particular device, product, operating system, current operator, or security state. The IEEE CSV records supplied here do not include assignment dates.
