ACARD Technology Corp. — MAC prefix identifies a registry assignment
Summary
- // what this is
- ACARD Technology is registered to MAC prefix
00:11:64in the IEEE OUI database. When a device's MAC address begins with00:11:64, that block was registered by ACARD Technology — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- A prefix match indicates a registry assignment only; it does not establish a particular device, product, deployment, traffic prevalence, current vendor identity, or security state.
About this vendor.
A MAC address beginning with 00:11:64 matches an IEEE MA-L assignment registered to ACARD Technology Corp.; the supplied evidence does not identify a device type or product for this prefix. A match identifies the assignment only, not a particular device, deployment, or current company status.
This 24-bit prefix leaves 24 bits for suffix values, or 16,777,216 possible values. That is a mathematical address-space count, not a count of devices or shipments. The IEEE CSV records supplied here do not include assignment dates.
For the exact prefix 00:11:64, the first octet is 00: its Group bit and Local bit are both zero. RFC 7042 explains these bits' significance for MAC identifiers. The match boundary is the first 24 bits; the remaining 24 bits vary within the assignment. Changing either first-octet bit changes the prefix and is not variation within this fixed prefix.
