Accensus LLC MAC Prefix DC:1E:A3 — Device Unknown

A MAC address beginning DC:1E:A3 identifies an IEEE MA-L assignment registered to Accensus LLC; the assignment does not identify a particular device or device category. The supplied evidence contains no first-party product information or mapping from this prefix to deployed equipment, so the device identity is unknown.

The assignment covers the first 24 bits of a 48-bit MAC identifier. A captured address matching those first three octets is consistent with the registry assignment, but does not establish who currently operates the device, its product, or its safety. The remaining 24 bits allow 16,777,216 possible suffix values; that is a mathematical address-space count, not a device or shipment count.

For this exact prefix, the first octet DC has Group bit 0 and Local bit 0. Those bits are fixed by the literal prefix match: changing either bit changes the prefix and no longer matches DC:1E:A3. RFC 7042 describes the significance of these bits in MAC identifiers. The IEEE CSV record gives the country as US, but supplies no assignment date. Assignment dates are unavailable in these IEEE CSV records.
