Alcohol Monitoring Systems MAC Prefix: Vendor Identified, Device Unknown

A MAC address beginning 00:24:DB matches an IEEE MA-L assignment to Alcohol Monitoring Systems; the supplied records do not identify a device category using it. The assignment names the registry holder, but does not establish which products use the prefix or whether a captured address is deployed by the company today.

The supplied company page describes SCRAM as remote alcohol monitoring: an ankle bracelet measures ethanol through the skin and sends readings by radio to a modem, which relays data to the web-based SCRAMNET service. This is company product context only; the page does not map SCRAM or any other product to 00:24:DB.

This is a 24-bit prefix, leaving 24 bits for suffix values: 16,777,216 possible values. The first byte 00 has Group bit 0 and Local bit 0, so the exact prefix denotes an individual, universally administered address range. RFC 7042 explains that these bits govern group versus individual and local versus universal interpretation. Changing either bit changes the prefix; the suffix-value count is not a device or shipment count.

A matching address supports the prefix comparison and assignment attribution, not identification of a particular device, operating system, traffic prevalence, or security state.
