Aker Subsea Ltd MAC Prefix Identification
Summary
- // what this is
- Aker Subsea is registered to MAC prefix
A8:95:B0in the IEEE OUI database. When a device's MAC address begins withA8:95:B0, that block was registered by Aker Subsea — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- A matching address has the first 24 bits A8:95:B0. The prefix’s first-byte Group and Local bits are both 0; changing either bit produces a different prefix. The 24-bit suffix permits 16,777,216 possible values, not a device or shipment count. A prefix match identifies a registry assignment, not a specific device or current legal identity.
About this vendor.
A MAC address beginning A8:95:B0 matches an IEEE MA-L assignment to Aker Subsea Ltd. This identifies the registry holder recorded for the prefix; it does not establish a particular device, product, deployment, or current company identity. The IEEE record does not provide assignment dates. [https://standards-oui.ieee.org/oui/oui.csv]
The prefix is 24 bits long, leaving 24 bits for suffix values: 16,777,216 possible values. That arithmetic describes the address space available under the prefix, not a count of devices or shipments. A matching address establishes only that its first 24 bits equal A8:95:B0.
In the first byte, A8 has Group bit 0 and Local bit 0, consistent with the bit interpretation described in RFC 7042. Those bits are fixed for this exact prefix. Changing either bit changes the prefix and therefore does not describe variation within this assignment. [https://www.rfc-editor.org/rfc/rfc7042.txt]
