Acromag, Inc. MAC Prefix: Vendor Assignment Identified
Summary
- // what this is
- Acromag is registered to MAC prefix
00:01:C3in the IEEE OUI database. When a device's MAC address begins with00:01:C3, that block was registered by Acromag — the OUI identifies the maker of the network hardware, which is not always the brand on the device.
About this vendor.
A MAC address beginning with 00:01:C3 matches the IEEE MA-L assignment to Acromag, Inc.; it does not identify a particular device or product. The available company page describes Acromag’s industrial I/O and defense products, but does not link any product or device category to this prefix.
Acromag says it was established in 1957 and makes process instrumentation and embedded I/O products. Its catalog includes signal conditioning modules, networked I/O, and analog, digital, serial, and FPGA I/O for several computer systems. These company-level product details provide context, not evidence that a specific product uses the assigned prefix.
00:01:C3 is a 24-bit MA-L prefix, leaving 24 bits for suffix values: 16,777,216 possible values. In this exact prefix, the first-byte Group and Local bits are both zero. A captured address matching the prefix therefore has those bits fixed; changing either bit produces a different prefix. The suffix-value count is not a count of devices, shipments, or addresses observed in use. IEEE records provided here do not include assignment dates.
