Alektrona Corporation — MAC prefix 00:1C:CD identifies an IEEE registry assignment
Summary
- // what this is
- Alektrona is registered to MAC prefix
00:1C:CDin the IEEE OUI database. When a device's MAC address begins with00:1C:CD, that block was registered by Alektrona — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- The exact 24-bit prefix has Group bit 0 and Local bit 0 in its first byte. A MAC matching the prefix establishes the registry assignment, not a particular device or product. There are 16,777,216 possible 24-bit suffix values; this is not a device or shipment count.
About this vendor.
A MAC address beginning with 00:1C:CD matches an IEEE MA-L assignment to Alektrona Corporation; the supplied evidence does not identify a device or product using it. A match establishes the registry prefix only, not the device’s maker, operating system, deployment, or security state.
The assignment is 24 bits long, leaving 24 suffix bits, or 16,777,216 possible suffix values. That is a mathematical address-space size, not a count of devices or shipments. RFC 7042 explains that the Group and Local bits have special meaning in the first octet of a MAC identifier.
For this prefix, the first octet is 00: its Group bit and Local bit are both zero. Those bits are fixed for an exact 00:1C:CD prefix match. Changing either bit changes the prefix, so variation within the assigned prefix must not be confused with changing its assignment semantics.
