A.I. ANTITACCHEGGIO ITALIA SRL: MAC prefix identification
Summary
- // what this is
- A.I. Antitaccheggio Italia is registered to MAC prefix
00:25:06in the IEEE OUI database. When a device's MAC address begins with00:25:06, that block was registered by A.I. Antitaccheggio Italia — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- A match identifies the IEEE registry assignment only; it does not establish a specific device or actual deployment. The 24-bit prefix leaves 24 suffix bits (16,777,216 possible values). Its first-byte Group and Local bits are both zero; changing either bit yields a different prefix.
About this vendor.
A MAC address beginning 00:25:06 matches an IEEE MA-L assignment registered to A.I. ANTITACCHEGGIO ITALIA SRL. The record identifies the registrant; it does not establish which device or product uses a matching address. No device category or product-to-prefix mapping is documented in the supplied evidence.
00:25:06 is a 24-bit prefix, leaving 24 bits for suffix values: 16,777,216 possible values. That is a mathematical address-space count, not a count of devices, shipments, or addresses actually in use. A captured address that matches this prefix supports the registry match only.
The first octet is 00. Its Group bit (bit 0) and Local bit (bit 1) are both zero, as shown by the supplied address interpretation. Those bits are fixed for this exact literal prefix; changing either produces a different prefix. RFC 7042 describes MAC identifiers as an initial OUI or longer assigned prefix followed by remaining identifier bits, and explains the Group and Local bits. The IEEE record provides no assignment date.
