MAC address vendor

NXP Semiconductors Germany GmbH MAC prefixes: vendor assignment

Primary prefix
04:CE:D8
Block
MA-L

Summary

// what this is
NXP Semiconductors Germany is registered to MAC prefix 04:CE:D8 and 1 more in the IEEE OUI database. When a device's MAC address begins with 04:CE:D8, that block was registered by NXP Semiconductors Germany — the OUI identifies the maker of the network hardware, which is not always the brand on the device.
// analyst note
A literal match on either 24-bit prefix has Group bit 0 and Local bit 0 in its first octet; changing either bit gives a different prefix. Each prefix has 24 suffix bits, or 16,777,216 possible suffix values; this does not indicate an actual device or shipment count. A registry match identifies the assignment, not a device, deployment, current legal identity, or security state.

About this vendor.

Updated  ·  Confidence: High  ·  2 sources  ·  How this page is checked

A MAC address beginning with 04:CE:D8 or 9C:02:13 matches an IEEE MA-L assignment to NXP Semiconductors Germany GmbH; the records do not identify a device category or product for either prefix.

Both are 24-bit prefixes, leaving 24 bits (16,777,216 possible suffix values) per prefix. That is a mathematical address space, not a count of devices or shipments. A match establishes the registered prefix only; it does not establish where an address was deployed or whether it is currently in use.

For both literal prefixes, the first octet has Group bit 0 and Local bit 0. RFC 7042 describes these bits as distinguishing group and local use; flipping either bit changes the prefix, so those variants are not matches to these exact assignments. The record identifies the legal registrant, but does not establish a device type, product mapping, or current corporate status.
