Akuvox (Xiamen) Networks: MAC Prefix 0C:11:05 Identifies a Registry Assignment

A MAC address beginning 0C:11:05 matches an IEEE MA-L assignment to AKUVOX (XIAMEN) NETWORKS CO., LTD; the prefix alone does not identify a device model or prove which vendor currently operates a device. Akuvox’s privacy notice describes the legal entity as a smart intercom products provider based in China. Its catalog includes intercom and access control products, but the retrieved material does not map those products to this prefix.

This is one 24-bit assignment. The matching boundary is the first 24 bits of a 48-bit address, leaving 24 suffix bits, or 16,777,216 possible suffix values. That is a mathematical range, not a count of devices or shipments. In the first octet 0C, the Group bit and Local bit are both zero, so both are fixed for an exact prefix match. Changing either bit produces a different prefix; these bits do not describe variation within this assignment.

RFC 7042 explains MAC address prefixes and these bit meanings. Use the match as an assignment clue, not as evidence of deployment, prevalence, or security state.
