Acrowave Systems Co., Ltd. — MAC prefix identifies a registry assignment; device type Unknown
Summary
- // what this is
- Acrowave Systems is registered to MAC prefix
00:04:47in the IEEE OUI database. When a device's MAC address begins with00:04:47, that block was registered by Acrowave Systems — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- A MAC prefix match identifies the IEEE registry assignment only; it does not establish a specific device, deployment, or safety state.
About this vendor.
A MAC address beginning 00:04:47 matches an IEEE MA-L assignment registered to Acrowave Systems Co., Ltd.; the supplied evidence does not identify a device category for this prefix. This match establishes the registered organization and prefix boundary, not which device made the address or whether the assignment is deployed.
The prefix is 24 bits, leaving 24 bits for suffix values within the 48-bit address space. That permits 16,777,216 possible suffix values, a mathematical range rather than a count of devices or shipments. The first-byte Group and Local bits are both zero for this exact prefix. RFC 7042 describes these bits as significant in MAC addresses; changing either bit changes the prefix and is not variation within this fixed assignment.
The IEEE record lists the registered organization name “Acrowave Systems Co., Ltd.” and an address string that includes “KOREA.” The available CSV extracts contain one MA-L assignment and no MA-M or MA-S assignment for this name. Assignment dates are not provided in these extracts.
