S Mobile Devices Limited: MAC prefix assignments, device unknown
Summary
- // what this is
- S Mobile Devices is registered to MAC prefix
50:A8:3Aand 1 more in the IEEE OUI database. When a device's MAC address begins with50:A8:3A, that block was registered by S Mobile Devices — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- A MAC match identifies the 24-bit registry prefix only. For both prefixes the Group and Local bits are zero; compare all 24 prefix bits for an exact match. Each leaves 24 suffix bits (16,777,216 possible values), which is not a device or shipment count.
About this vendor.
A MAC address beginning with 50:A8:3A or 30:F7:7F matches an IEEE MA-L assignment to S Mobile Devices Limited; the available evidence does not identify a device category or product for either prefix. A match identifies the registered prefix only, not a particular device, operating system, deployment, or security state.
Both assignments are 24-bit prefixes in a 48-bit MAC identifier, leaving 24 bits for suffix values. Each therefore has 16,777,216 possible suffix values; that arithmetic does not indicate how many devices were made or observed. The first-byte Group and Local bits are zero for both exact prefixes. Under RFC 7042, these bits distinguish group and locally administered address semantics; changing either bit changes the prefix match. For address identification, compare the first 24 bits exactly.
The IEEE records list the registered organization name and a country indication (IN), but provide no assignment dates. The supplied evidence contains no product catalog, industry description, or first-party company material, so those company-level details cannot be established here.
