Siemens Canada — 3 prefixes (MA-L)

A MAC address starting with 50:00:84, F8:15:E0, or 24:ED:FD belongs to Siemens Canada (registered as "Siemens Canada" for two blocks and "Siemens Canada Limited" for the third), the Canadian subsidiary of Siemens AG, and typically shows up on industrial networking or process-instrumentation hardware rather than consumer or general office equipment.

The three blocks trace to two distinct, independently documented Siemens Canada facilities. 50:00:84 and F8:15:E0 register to 300 Applewood Crescent, Concord, Ontario — the former RuggedCom Inc. site, home to Siemens' RUGGEDCOM line of rugged industrial Ethernet switches, routers, and media converters. 24:ED:FD registers to 1954 Technology Drive, Peterborough, Ontario, the Siemens Milltronics Process Instruments plant that builds ultrasonic level-measurement transmitters such as the SITRANS Probe LU240.

Siemens acquired RuggedCom Inc. in a deal that closed January 30, 2012, folding its networking line into the Siemens portfolio. Siemens announced in June 2025 that it is winding down Peterborough manufacturing over roughly two years and consolidating that work into Concord, retaining about 40 staff at Peterborough in the interim.

The facility-to-product mapping above is an inference from the registered street address matching each site's known business, not a first-party "this OUI ships on product X" statement — treat the RuggedCom-versus-Milltronics device-class attribution as likely rather than confirmed. Concord's RUGGEDCOM ROS products have also been the subject of multiple CISA ICS-CERT advisories over the years, so hardware on these prefixes should generally be treated as OT/industrial-network equipment.

Registration date

Unknown as an IEEE fact — IEEE's MA-L registry carries no assignment/registration date field for any of the three blocks. Third-party "registered" dates seen on maclookup.app (2018-10-13, 2024-11-15) are database artifacts, not IEEE facts, and are not recorded here as registration dates
