Vivint Wireless Inc. MAC Prefix Identification

A MAC address beginning with A0:FE:61 or 5C:2B:F5 matches an IEEE MA-L assignment to Vivint Wireless Inc.; the records do not identify a device category or specific product for either prefix. A match identifies the registered prefix only, not a particular device, deployment, or current company identity.

Both assignments are 24-bit prefixes, leaving 24 bits (16,777,216 possible suffix values) under each prefix. These are mathematical address possibilities, not counts of devices or shipments. The matching boundary is the first three octets; the remaining three octets may vary.

For both listed prefixes, the first octet has Group bit 0 and Local bit 0. RFC 7042 describes those bits as significant in MAC addresses: changing either bit changes the prefix and no longer matches the exact listed prefix. The IEEE records provide no assignment dates.
