Danlaw Inc — 2 MA-L prefixes (automotive telematics)

A MAC address starting with 4C:CE:2D or 08:90:BA belongs to Danlaw Inc, an automotive telematics and embedded-electronics supplier, and typically appears on vehicle diagnostic hardware such as OBD-II data loggers and vehicle-to-everything (V2X) communication units.

IEEE's public OUI registry lists both blocks as full MA-L (24-bit) assignments to Danlaw Inc, registered at 23700 Research Dr, Farmington Hills, MI 48335, US. Danlaw also holds a /36 sub-allocation, 00:50:C2:27:C0/36, inside the shared IEEE Registration Authority base 00:50:C2, corroborated by the Wireshark the Wireshark manufacturer database list and third-party lookup sites, though it is absent from the local the IEEE MA-S registry.

That shared base matters: 00:50:C2 itself is registered to the IEEE Registration Authority and sub-delegated to many unrelated companies, so a MAC merely starting 00:50:C2 does not indicate Danlaw hardware — only the specific 00:50:C2:27:C0/36 slice does. The two MA-L blocks, by contrast, are Danlaw's own full /24 assignments.

Danlaw is a 30-plus-year automotive telematics supplier with FCC-registered hardware including the DL815 Data Logger Vehicular Transceiver and the DCM970 Data Logger GEN 3, both OBD-II-connected devices used for vehicle diagnostics and connected-car telemetry. No CVE or malware association is on record for these devices as of an August 2026 web search.

Third-party lookup site maclookup.app lists "date registered" values of 23 January 2020 and 2 June 2018 for the two blocks; these are database artifacts, not IEEE facts, since IEEE's the IEEE MA-L registry publishes no assignment-date field for OUI registrations.

IEEE assignment

4C:CE:2D and 08:90:BA → Danlaw Inc, registered Farmington Hills, MI, US [Confirmed] — the IEEE MA-L registry 4CCE2D, the IEEE MA-L registry 0890BA

Registry / block size

MA-L (24-bit OUI); holds 2 IEEE MA-L prefixes plus a /36 sub-allocation under shared base 00:50:C2 [Confirmed for the two MA-L blocks; Likely for the /36 — corroborated by the Wireshark manufacturer database and third-party sites, not present in the IEEE MA-S registry] — the IEEE MA-L registry; the Wireshark manufacturer database (00:50:C2:27:C0/36)

HQ / country

Shared-base caveat

00:50:C2 as a whole is registered to "IEEE Registration Authority," not Danlaw; only 00:50:C2:27:C0/36 is Danlaw's sub-allocation, per the Wireshark the Wireshark manufacturer database list and not present in local the IEEE MA-S registry [Likely] — the IEEE MA-L registry (IEEE Registration Authority row), the Wireshark manufacturer database, https://hwaddress.com/oui-iab/00-50-C2/, https://mac.lc/address/00:50:C2

Third-party date caveat

maclookup.app lists "23 January 2020" (4CCE2D) and "02 June 2018" (0890BA) as "date registered" — these are third-party database artifacts, not IEEE facts; IEEE's the IEEE MA-L registry publishes no assignment-date field

Analyst note

Danlaw Inc holds two full MA-L OUI-24 blocks plus a /36 sub-allocation within the shared IEEE-RA base 00:50:C2, tied to named automotive-telematics hardware; that attribution does not extend to any MAC merely starting 00:50:C2, which belongs to the IEEE Registration Authority and is sub-delegated to many unrelated companies.
