Adcon Telemetry GmbH MAC Prefix: Vendor Identified, Device Unknown
Summary
- // what this is
- Adcon Telemetry is registered to MAC prefix
00:04:D2in the IEEE OUI database. When a device's MAC address begins with00:04:D2, that block was registered by Adcon Telemetry — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- A 24-bit exact prefix match requires the first three octets. The first-byte Group and Local bits are both zero; toggling either bit produces a different prefix. There are 16,777,216 possible 24-bit suffix values, not an observed device or shipment count. A prefix match establishes a registry assignment only.
About this vendor.
A MAC address beginning 00:04:D2 matches an IEEE MA-L assignment to Adcon Telemetry GmbH; the record does not identify a device category or product. The assignment is a registry association, so a matching address alone cannot establish who deployed the interface, whether it is active, or its safety. [IEEE record](https://standards-oui.ieee.org/oui/oui.csv)
This is a 24-bit prefix: matching requires the first three octets, 00:04:D2. The remaining 24 bits allow 16,777,216 possible suffix values, not a count of devices, shipments, or observed addresses. In the first octet 00, the Group bit and Local bit are both zero, consistent with the RFC’s described assignment convention. Flipping either bit changes the first octet and therefore no longer matches this exact prefix. [RFC 7042](https://www.rfc-editor.org/rfc/rfc7042.txt)
The IEEE CSV record contains AT as the country indication, reported here as Austria. Assignment dates are unavailable in these IEEE CSV records. No product catalog or device mapping is supplied, so device and product identification beyond the registered company remains unknown.
