AIM SYSTEM, INC. — MAC prefix identifies registry assignment
Summary
- // what this is
- AIM System is registered to MAC prefix
00:D0:20in the IEEE OUI database. When a device's MAC address begins with00:D0:20, that block was registered by AIM System — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- A match identifies the MA-L registry assignment, not a particular device or deployment. The prefix is 24 bits, leaving 24 suffix bits (16,777,216 possible values, not an observed device count). For exact prefix 00:D0:20, the Group and Local bits are both zero; changing either bit changes the prefix.
About this vendor.
A MAC address beginning 00:D0:20 matches the MA-L assignment recorded to AIM SYSTEM, INC.; the supplied evidence does not identify a device category or a specific product for this prefix.
This is a 24-bit prefix, leaving 24 bits for suffix values: 16,777,216 possible values. That arithmetic describes the address space, not a count of devices or shipments. A match identifies the registry assignment and cannot by itself establish the maker of a particular device, its current operator, or its safety.
For this exact prefix, the first-octet Group bit and Local bit are both zero. Changing either bit changes the prefix, so this interpretation applies only to addresses matching the literal 00:D0:20 prefix. RFC 7042 explains the role of these bits and the structure of 48-bit MAC identifiers.
