Abbott Diagnostics MAC Prefix: Registered Assignment, Product Unknown

Primary prefix
00:13:DD
Block
MA-L

Summary

// what this is
Abbott Diagnostics is registered to MAC prefix 00:13:DD in the IEEE OUI database. When a device's MAC address begins with 00:13:DD, that block was registered by Abbott Diagnostics — the OUI identifies the maker of the network hardware, which is not always the brand on the device.
// analyst note
The 00:13:DD prefix is 24 bits, leaving 24 suffix bits (16,777,216 possible values, not a device or shipment count). Its first octet 00 has Group bit 0 and Local bit 0; changing either bit yields a different prefix. A match indicates the registry assignment only, not a specific device, product, deployment, or security state. RFC 7042 explains MAC prefix structure and the Group and Local bits.

A MAC address beginning 00:13:DD matches an IEEE MA-L assignment registered to Abbott Diagnostics; the record does not identify a device or product using it. The captured prefix supports a registry match only, not a device model, deployment, or security conclusion.

This is a 24-bit prefix, leaving 24 bits for suffix values: 16,777,216 possible values. That is a mathematical address-space size, not a count of devices or shipments. A match requires the first 24 bits to equal 00:13:DD; later bits may vary.

The first octet is 00 (binary 00000000). Its Group bit (bit 0) and Local bit (bit 1) are both zero for this exact prefix. Changing either bit changes the prefix and no longer matches this assignment. RFC 7042 describes these bit meanings for MAC addresses and explains the relationship between 48-bit identifiers and assigned prefixes. The supplied record contains no assignment date.
