ALCEA MAC prefix 34:FC:6F: vendor identification only

A MAC address beginning 34:FC:6F is assigned to ALCEA in the IEEE MA-L registry; that assignment alone does not identify a device type or prove that ALCEA made the device. No device category or product-to-prefix mapping is established by the supplied records.

The assignment is 24 bits long, leaving 24 bits in a 48-bit MAC address. The remaining bits allow 16,777,216 possible suffix values, not a count of devices, addresses in use, shipments, or observed traffic. A matching prefix supports registry attribution only; it does not establish current vendor identity, deployment, or security status.

RFC 7042 explains the Group and Local bits in the first octet. For this literal prefix, both are fixed at zero (34 hexadecimal): the Group bit is clear and the Local bit is clear. Changing either bit changes the prefix and therefore does not match this exact assignment. The supplied IEEE CSV record does not include assignment dates.

Assigned prefix

34:FC:6F (MA-L, 24 bits) [Confirmed] — https://standards-oui.ieee.org/oui/oui.csv

Device category

Unknown; no supplied source maps a device category to this exact prefix.

Group and Local bits

Both are zero in the first octet 34; changing either bit produces a different literal prefix [Confirmed] — https://www.rfc-editor.org/rfc/rfc7042.txt

Possible suffix values

16,777,216 values across the remaining 24 bits; this is not a device or shipment count [Confirmed] — https://www.rfc-editor.org/rfc/rfc7042.txt
