Schneider Electric — 7 prefixes (6 MA-L + 1 MA-M)

This entry groups seven IEEE OUI assignments registered under the exact organization name "Schneider Electric" (no qualifying suffix): six MA-L blocks (9C:0E:51, 00:11:00, 00:00:54, 00:03:74, 00:05:21, and 00:00:6C) plus one MA-M /28 sub-block (base 08:8D:F4:5, IEEE assignment 008DF45, registered at Schneiderplatz 1, Marktheidenfeld, DE 97828). Four of the six MA-L rows carry a Rueil-Malmaison, France address tied to the company's global HQ area; two of them (00:11:00 and 00:00:6C) list US addresses in Leesport, PA and Foxboro, MA, reflecting acquired US operations, while the MA-M block sits at the company's Marktheidenfeld, Germany site. Schneider Electric SE is a French multinational energy-management and industrial-automation conglomerate — Fortune Global 500, roughly 160,000 employees, reporting €38.15B in FY2024 revenue — so this is a substantive, identifiable company with a large product footprint, not a bare shell registration. Devices tied to Schneider hardware include Modicon Network Managed Switches, EcoStruxure Panel Server edge gateways, SCADAPack x70 Modbus TCP RTUs, and EcoStruxure Foxboro DCS controllers, all of which appear in recent CISA ICS advisories alongside an active vendor security-notification program. A distinct registry oddity worth flagging: two of the six rows (00:03:74, 00:05:21) list country code "CA" next to a French city and postal code — the registry data is reproduced as published rather than silently corrected. Sibling entities that share the "Schneider Electric" name but carry a qualifier — APC by Schneider Electric, Schneider Electric USA, Schneider Electric Canada Inc, Schneider Electric Asia Pacific Ltd, Schneider Electric Motion, and others — hold their own separate OUI rows and slugify to different vendor-* entries; they are not part of this group.

IEEE assignment

7 OUIs registered to "Schneider Electric" exactly — 6 MA-L (9C:0E:51, 00:11:00, 00:00:54, 00:03:74, 00:05:21, 00:00:6C) + 1 MA-M /28 (base 08:8D:F4:5, assignment 008DF45) [Confirmed] — the IEEE MA-L registry + the IEEE MA-M registry (direct registry read)

Registry / block size

6 MA-L (24-bit OUI) blocks + 1 MA-M (28-bit /28 sub-block, 08:8D:F4:5 under Marktheidenfeld DE) under this exact-name group; qualified siblings (USA, Canada, Asia Pacific, Motion, APC, Schneider Electric Korea MA-M 2C6A6FB, etc.) are separate registry rows / separate vendor-* entries

[Confirmed] — the IEEE MA-L registry, the IEEE MA-M registry; grouping per this site's own tooling slug algorithm

Registered addresses

4 of the 6 MA-L rows list 35 Rue Joseph Monier, Rueil-Malmaison, France (HQ area); 2 US rows — 5460 Pottsville Pike, Leesport, PA 19533 (00:11:00) and 70 Mechanic Street, Foxboro, MA 02035 (00:00:6C); the MA-M block (08:8D:F4:5) lists Schneiderplatz 1, Marktheidenfeld, DE 97828

[Confirmed] — the IEEE MA-L registry, the IEEE MA-M registry

Registry anomaly

rows 00:03:74 and 00:05:21 list country code "CA" alongside the French city/postal 92500 — reproduced as-published, not corrected [Confirmed anomaly, as-published] — the IEEE MA-L registry

Related / excluded entries

"Schneider Electric USA", "Schneider Electric Canada Inc", "Schneider Electric Asia Pacific Ltd", "APC by Schneider Electric", "Schneider Electric Motion Usa", "Schneider Electric Fire & Security Oy", "Schneider Electric Japan Holdings Ltd." and similar qualified names hold separate OUI rows and are NOT part of this group

[Confirmed] — the IEEE MA-L registry (direct registry read)

Date field

IEEE's public OUI data (the IEEE MA-L registry columns: Registry, Assignment, Organization Name, Organization Address) has no assignment/registration date column; "date registered" values shown by third-party lookup tools are database artifacts, not IEEE facts — no date is recorded for this entry

[Confirmed] — the IEEE MA-L registry structure; https://maclookup.app/vendors/schneider-electric (illustrates the artifact)

Historic / oldest block among the 6

Unknown — IEEE publishes no per-OUI dates, so relative chronology cannot be determined from registry data alone [Unknown]
