AK-Systems Ltd: MAC prefix identifies a registry assignment; device type Unknown
Summary
- // what this is
- AK-Systems is registered to MAC prefix
00:E1:75in the IEEE OUI database. When a device's MAC address begins with00:E1:75, that block was registered by AK-Systems — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- An exact
00:E1:75prefix match fixes the first-byte Group and Local bits at zero. This 24-bit prefix leaves 24 suffix bits (16,777,216 possible values), not a device or shipment count. A match indicates the registry assignment, not a particular device or deployment.
About this vendor.
A MAC address beginning 00:E1:75 matches an IEEE MA-L assignment to AK-Systems Ltd. The available evidence does not identify a device category or establish which products, if any, use this prefix, so the device type is Unknown. A prefix match identifies the registry assignment; it does not identify a particular device, operating system, current legal identity, or security state.
This is a 24-bit prefix in a 48-bit address, leaving 24 bits for suffix values: 16,777,216 possible values. That is a mathematical address space, not a count of devices or shipments. The listed prefix fixes the first-byte Group bit and Local bit at zero. Changing either bit changes the prefix, so those changes are not variations within this exact assignment.
RFC 7042 describes 48-bit MAC identifiers as an assigned initial prefix followed by additional bits, and explains the Group and Local bits. The supplied IEEE CSV record has no assignment date. No first-party company material was supplied to establish products, industry, website, or related vendors.
