MAC address vendor

NIKON CORPORATION MAC Prefixes: Device Type Unknown

Primary prefix
3C:BE:E1
Block
MA-L

Summary

// what this is
Nikon is registered to MAC prefix 3C:BE:E1 and 1 more in the IEEE OUI database. When a device's MAC address begins with 3C:BE:E1, that block was registered by Nikon — the OUI identifies the maker of the network hardware, which is not always the brand on the device.
// analyst note
Each 24-bit prefix leaves 24 suffix bits (16,777,216 possible values), which is an address-space count, not an observed device or shipment count. For both exact prefixes, the first-octet Group and Local bits are 0; changing either bit yields a different prefix. A prefix match identifies a registry assignment and does not establish a specific device or security state.

A MAC address beginning with 3C:BE:E1 or 00:90:B5 matches an IEEE MA-L assignment registered to NIKON CORPORATION; the assignment alone does not identify a device type or prove that the address is used by a Nikon product. The IEEE records show two assignments under the exact legal name, and give JP in their address data, indicating Japan.

Both prefixes are 24 bits long, so each matches the first three octets of a 48-bit MAC address. Each leaves 24 suffix bits, or 16,777,216 possible suffix values. That number describes address space, not a count of devices, shipments, or addresses actually in use.

For both prefixes, the first octet has Group bit 0 and Local bit 0: 3C and 00 each have those two least-significant bits clear. Those values are fixed for an exact prefix match; changing either bit produces a different prefix. RFC 7042 describes 48-bit MAC identifiers as an assigned initial prefix followed by additional bits. A captured match supports the registry-assignment identification, but does not establish a particular device, operating system, current vendor identity, or security state.
