Loxone Electronics GmbH MAC prefixes: vendor identified, device unknown
Summary
- // what this is
- Loxone Electronics is registered to MAC prefix
50:4F:94and 1 more in the IEEE OUI database. When a device's MAC address begins with50:4F:94, that block was registered by Loxone Electronics — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- Each 24-bit prefix leaves 24 suffix bits, or 16,777,216 possible suffix values; this is not a device or shipment count. In both prefixes, Group and Local bits are zero. These bit values are fixed for the exact prefix; changing either bit produces a different prefix. A match identifies a registry assignment only, not a particular device, operating system, deployment, current legal identity, or security state.
About this vendor.
A MAC address beginning with 50:4F:94 or 78:52:49 matches an IEEE MA-L assignment to Loxone Electronics GmbH; the supplied evidence does not identify a device category or product for either prefix.
Both assignments are 24-bit prefixes, leaving 24 bits for suffix values. Each therefore has 16,777,216 possible suffix values, a mathematical address space size rather than a count of devices or shipments. RFC 7042 explains that 48-bit MAC identifiers can use an initial OUI followed by additional bits, and that the Group and Local bits have special significance.
For both listed prefixes, the first octet has Group bit 0 and Local bit 0. Those bit values are fixed for an exact literal prefix match. Setting either bit would change the prefix, so it would no longer be an exact match to these assignments. A match establishes the registered prefix only; it does not establish which device used the address, its deployment, or its security state.
