Alereon, Inc. MAC Prefix: Vendor Identified, Device Unknown

A MAC address beginning 00:1D:8E matches an IEEE MA-L assignment registered to Alereon, Inc.; the supplied evidence does not identify a device category or specific product using it. A prefix match identifies the registry assignment, not a particular device, operating system, current legal identity, or security state.

This assignment covers the first 24 bits of a 48-bit MAC address, leaving 24 suffix bits, or 16,777,216 possible suffix values. That is a count of possible values, not an observed device or shipment count. The exact assigned prefix fixes the first-byte Group and Local bits at zero; changing either bit produces a different prefix and is not variation within this assignment.

The supplied IEEE record gives the legal registrant name and indicates the United States. It provides no assignment date. RFC 7042 describes 48-bit MAC identifiers as using an initial OUI or longer assigned prefix followed by additional bits.
