Actioncable, Inc. — MAC prefix A0:40:25 identification
Summary
- // what this is
- Actioncable is registered to MAC prefix
A0:40:25in the IEEE OUI database. When a device's MAC address begins withA0:40:25, that block was registered by Actioncable — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- An exact A0:40:25 match identifies the MA-L registry assignment. For this prefix, the first-octet Group and Local bits are both 0; either bit changing would yield a different prefix. The 24-bit remainder permits 16,777,216 suffix values, not an observed device or shipment count.
About this vendor.
A MAC address beginning A0:40:25 matches the IEEE MA-L assignment to Actioncable, Inc.; the supplied records do not identify a device category or product that uses it. This match identifies the registered prefix only, not a specific device, deployment, or current vendor identity.
The prefix is 24 bits long, leaving 24 bits for suffix values—16,777,216 possible values. This is a mathematical address space, not a count of devices or shipments. RFC 7042 explains that MAC identifiers can use an assigned initial prefix with remaining bits available for additional identifiers.
For this particular prefix, the first octet A0 has Group bit 0 and Local bit 0. An exact A0:40:25 prefix match therefore has those bit values fixed; changing either bit produces a different prefix. A captured address matching the prefix supports identification of this registry assignment, but does not establish who deployed it or whether it is safe.
