Eaton Corporation — 5 prefixes (MA-L)

A MAC address beginning with 00:0C:C1, 00:13:45, 00:16:45, 00:18:64, or 00:20:85 belongs to Eaton Corporation (NYSE: ETN), most often seen on uninterruptible power supplies (UPS), power distribution units (PDUs), and the network management cards that let IT staff monitor and control that power hardware remotely.

These five blocks are all registered in the IEEE MA-L registry directly to "Eaton Corporation," at facility addresses in Waukesha WI, Milwaukee WI, Richmond VA, and Raleigh NC in the US, plus one Canadian address in St-Jean-Chrysostome, QC. The site's existing vendor page for this entry already lists all five prefixes together.

Beyond the bare registration, Eaton's networking-capable power products have a documented device and security history. The current network-connectivity card line is Network-M2 (end-of-life early 2024) and its successor Network-M3, both marketed with UL 2900-1 / IEC 62443-4-2 cybersecurity certifications; Eaton also ships IIoT power-monitoring and environmental (temperature/humidity) sensor hardware carrying the same OUI family.

Eaton runs a formal product-vulnerability disclosure program and periodically publishes security bulletins for these devices — for example ETN-VA-2025-1004, addressing the Network-M2 card with a recommended firmware upgrade to 3.1.17 plus SSH-restriction and firewall guidance.

The wider Eaton corporate family holds additional, separately-registered OUI and MA-M blocks under related but distinct legal-entity names — Eaton Automation AG, Eaton Industries GmbH, Eaton Corp. Electrical Group (Pulizzi), Eaton Bussmann, and EATON FHF Funke + Huster Fernsig GmbH — none of which are folded into this consolidated entry.
