Sector Alarm Tech S.L. MAC prefixes: device identification Unknown
Summary
- // what this is
- Sector Alarm Tech S.L is registered to MAC prefix
F8:D0:C5and 1 more in the IEEE OUI database. When a device's MAC address begins withF8:D0:C5, that block was registered by Sector Alarm Tech S.L — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- Each prefix is 24 bits, leaving 24 suffix bits and 16,777,216 possible suffix values; these are address-space possibilities, not device or shipment counts. Both have first-byte Group bit 0 and Local bit 0. Changing either bit yields a different prefix, and an exact match identifies the registry assignment only.
About this vendor.
A MAC address beginning with F8:D0:C5 or 7C:99:46 identifies an IEEE MA-L assignment to Sector Alarm Tech S.L.; the supplied evidence does not identify a device type or product using either prefix. A prefix match identifies the registered assignment, not a particular device, operating system, current company identity, or security state.
Both records are 24-bit prefixes, leaving 24 bits for suffix values. For each, the first-byte Group bit is 0 and Local bit is 0. These fixed values characterize the literal assigned prefixes; changing either bit produces a different prefix. The 16,777,216 possible suffix values per prefix are address-space possibilities, not counts of devices or shipments.
RFC 7042 explains that EUI-48 identifiers combine an initial OUI or other assigned prefix with additional bits, and describes Group and Local bit significance. A captured address can support a match to one of these assignments when its first three octets match exactly; it cannot establish deployment or prevalence. Assignment dates are unavailable in these IEEE CSV records.
- Device or vendor
- Sector Alarm Tech S.L. is the registry assignee; device category and product mapping are Unknown.
- Matching prefixes
F8:D0:C5and7C:99:46(MA-L).- Interpretation
- Each is an exact 24-bit prefix with Group bit 0 and Local bit 0; each allows 24 suffix bits.
- Limits
- A prefix match identifies the assignment only, not an individual device or deployment.
