Intrinsyc Software International Inc. — 2 prefixes (MA-L)

Intrinsyc Software International Inc. was a Vancouver, British Columbia embedded-computing and IoT design firm that held two MA-L OUI blocks: 00:06:3C and 00:D0:CA. Both registry entries carry the same legacy address — 885 Dunsmuir Street, Suite 380, Vancouver, B.C. V6C 1N5, Canada. The company's hardware lineage spans three eras: CerfBoard embedded single-board computers and reference designs from the Windows CE period of the late 1990s; Soleus, a Windows Embedded CE software platform for feature phones and converged handsets that it licensed to OEMs and ODMs (including Samsung System LSI) in the mid-2000s; and the Open-Q line of System-on-Module (SoM) compute modules and Hardware Development Kits built on Qualcomm Snapdragon processors, aimed at robotics, cameras, medical devices, wearables, industrial control, and IoT edge compute. Because Intrinsyc was primarily a design and engineering-services firm for silicon vendors and ODMs, these MAC ranges most often appear on development boards, prototype handsets, and SoM evaluation kits rather than mass-market retail devices — so encountering one of these prefixes on a production network is unusual and often signals a development device or legacy embedded hardware. The corporate entity was acquired by Lantronix, Inc. (definitive agreement October 31, 2019; final closing January 20, 2020); the intrinsyc.com domain now 301-redirects to lantronix.com, and the Open-Q product line continues under the Lantronix brand. A data-quality caveat: third-party MAC lookup sites display "Registration Date" values (2000-11-09 for 00:D0:CA, 2001-06-04 for 00:06:3C), but IEEE publishes no OUI registration dates — those are database artifacts and must not be recorded as IEEE facts.

IEEE assignment

2 prefixes → Intrinsyc Software International Inc. [Confirmed] — IEEE MA-L (lines 21476 and 21771)

Registry / block size

MA-L (24-bit OUI), both assignments; prefixes 00:06:3C and 00:D0:CA [Confirmed] — IEEE the IEEE MA-L registry; maclookup.app, hwaddress.com. No MA-M (the IEEE MA-M registry) or MA-S (the IEEE MA-S registry) assignments found. NOTE: IEEE's public OUI data publishes NO assignment/registration date; any "date registered" on third-party tools (e.g. 2000-11-09 / 2001-06-04) is a database artifact, not an IEEE fact.

Analyst note

A globally-administered 00:06:3C or 00:D0:CA address identifies genuine Intrinsyc-registered hardware, but given the design/prototyping nature of the product line, treat encounters as development or legacy embedded devices rather than mass-market endpoints. The vendor brand is defunct as a standalone entity (folded into Lantronix).
