About this vendor.

A MAC address beginning 8C:11:CB is registered to ABUS Security-Center GmbH & Co. KG, but the available evidence does not identify a device category or product for this prefix. The assignment establishes a registry relationship; it does not establish which equipment uses it or whether a captured address is currently deployed.

This is a 24-bit MA-L prefix. An exact match covers the first three octets, 8C:11:CB, leaving 24 suffix bits and 16,777,216 possible suffix values. That number describes address values, not devices, shipments, or observed traffic. A matching address supports identification of the registered prefix only.

The first octet 8C has Group and Local bits both clear: 8C & 01 and 8C & 02 are zero. For this exact prefix, those bits are fixed; changing either produces a different prefix. RFC 7042 describes these bits and the structure of 48-bit MAC identifiers. The IEEE CSV record indicates Germany (DE). Assignment dates are unavailable in these IEEE CSV records.
