QTECH LLC MAC prefixes: device identity unknown

A MAC address beginning with 00:1F:CE or 08:C6:B3 matches an IEEE MA-L assignment to the registry organization name QTECH LLC; the supplied records do not identify a device type. Both prefixes are listed under that organization name. The records identify the country as Russia. [IEEE OUI registry](https://standards-oui.ieee.org/oui/oui.csv)

Each assignment is 24 bits long, leaving 24 bits for suffix values: 16,777,216 possible suffixes per prefix. This is a mathematical range, not a count of devices, shipments, or addresses observed in use. RFC 7042 describes the Group and Local bits in the first octet; for these exact prefixes, both bits are fixed at zero. [RFC 7042](https://www.rfc-editor.org/rfc/rfc7042.txt)

A captured address matching either 24-bit prefix supports identifying the registry assignment. It does not establish a particular device, product, operating system, current vendor identity, or security state. Changing either first-octet bit changes the prefix, so the interpretation applies to exact matches only.

Device class

Unknown; the supplied records do not map either prefix to a device category.
