Aitexin Technology Co., Ltd — MAC prefix identifies a registry assignment
Summary
- // what this is
- Aitexin Technology is registered to MAC prefix
30:B5:F1in the IEEE OUI database. When a device's MAC address begins with30:B5:F1, that block was registered by Aitexin Technology — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- The /24 prefix has 24 suffix bits and 16,777,216 possible suffix values. For this exact prefix, the first-octet Group and Local bits are both zero; changing either bit yields a different prefix. Possible suffix values are not a device or shipment count. A match establishes a registry assignment only.
About this vendor.
A MAC address beginning 30:B5:F1 matches an IEEE MA-L assignment registered to Aitexin Technology Co., Ltd; the record does not identify a device category or product. The listed assignment is 30:B5:F1 (/24), with one prefix in the supplied projection.
For this prefix, the first octet is 30 hexadecimal. Its Group bit and Local bit are both zero, so a literal 30:B5:F1 match has those bits fixed. Changing either bit produces a different prefix; bit variation is not part of this exact prefix match. RFC 7042 describes the Group and Local bits in MAC identifiers.
The /24 leaves 24 suffix bits, allowing 16,777,216 possible suffix values. This is a mathematical address space size, not a count of devices, shipments, or addresses observed in use. A match supports the registry-assignment identification only; it does not establish a particular device, operating system, current legal identity, or security state. The supplied record indicates China.
