Accelerated Memory Production Inc. — MAC prefix identifies registry assignment only
Summary
- // what this is
- Accelerated Memory Production is registered to MAC prefix
30:23:BAin the IEEE OUI database. When a device's MAC address begins with30:23:BA, that block was registered by Accelerated Memory Production — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- A literal 30:23:BA match fixes the Group and Local bits of the first octet at 0; changing either bit yields a different prefix. The 24-bit assignment leaves 24 suffix bits, or 16,777,216 possible suffix values, which is not an observed device or shipment count. A prefix match identifies a registry assignment only.
About this vendor.
A MAC address beginning 30:23:BA matches the IEEE MA-L assignment registered to Accelerated Memory Production Inc.; the supplied evidence does not establish a device type or product for this prefix.
The assignment is 24 bits long, leaving 24 bits in a 48-bit address. That permits 16,777,216 possible suffix values under the prefix; it is a mathematical range, not a device or shipment count. RFC 7042 explains that MAC identifiers may use a 3-octet OUI followed by additional bits and describes the Group and Local bits.
For this exact prefix, the first octet is 30 hexadecimal: its Group bit is 0 and its Local bit is 0. Those bit values are fixed for a literal prefix match. Changing either bit changes the prefix and no longer matches this assignment. A match establishes only the registry assignment, not the identity or state of a particular device.
