Alcatel DI — MAC prefix identification

A MAC address beginning 00:11:3F matches an IEEE MA-L assignment registered to Alcatel DI; the record does not identify a device category or product. This prefix covers the first 24 bits of a 48-bit MAC address, leaving 24 bits after the prefix. A match identifies the registry assignment, not the device’s maker, current operator, deployment, or security state.

In the prefix 00:11:3F, the Group bit and Local bit are both zero. RFC 7042 says MAC prefixes are assigned with the Local bit zero and the Group bit unspecified; it also says multicast identifiers may be constructed by turning on the Group bit. The assignment record identifies 00:11:3F as an MA-L assignment to Alcatel DI. Its remaining 24 bits allow 16,777,216 possible suffix values; this count does not establish how many devices use the prefix.

The IEEE record includes FR, an unambiguous country indication for France. Assignment dates are unavailable in these IEEE CSV records. RFC 7042 explains the structure and interpretation of 48-bit MAC identifiers and their assigned prefixes.
