Aksys, Ltd. MAC prefix: vendor assignment, device unknown
Summary
- // what this is
- Aksys is registered to MAC prefix
00:0E:D9in the IEEE OUI database. When a device's MAC address begins with00:0E:D9, that block was registered by Aksys — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- A literal 00:0E:D9 match fixes Group and Local bits at 0. The 24-bit suffix allows 16,777,216 possible values, not an actual device or shipment count. A match indicates the registry assignment only.
About this vendor.
A MAC address beginning 00:0E:D9 matches an IEEE MA-L assignment registered to Aksys, Ltd.; the supplied records do not identify a device category. The assignment establishes a registry match, not the manufacturer of a particular device, current vendor identity, or whether the address was deployed in traffic.
This is a 24-bit prefix, leaving 24 bits for suffix values: 16,777,216 possible values. That is a mathematical range, not a count of devices or shipments. For this exact prefix, the first octet is 00: its Group bit is 0 and its Local bit is 0. Those bits are fixed for a literal match; changing either bit produces a different prefix. RFC 7042 describes these bits and the structure of 48-bit MAC identifiers.
The supplied IEEE CSV record gives the registrant name and a U.S. country indication, but no assignment date. No company products or device categories are established by the supplied evidence.
- Registry match
- Aksys, Ltd. (MA-L)
- Device identification
- Unknown; no device category is mapped to this prefix in the supplied evidence.
- Address match
00:0E:D9matches the first 24 bits of a 48-bit MAC identifier.- Bit interpretation
- Group bit 0; Local bit 0 for this exact prefix.
- Suffix range
- 24 bits, or 16,777,216 possible suffix values; this is not a device count.
