AC Tech corporation DBA Advanced Digital — device identity unknown
Summary
- // what this is
- AC Tech corporation DBA Advanced Digital is registered to MAC prefix
00:0C:61in the IEEE OUI database. When a device's MAC address begins with00:0C:61, that block was registered by AC Tech corporation DBA Advanced Digital — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- The 24-bit prefix leaves 24 suffix bits, or 16,777,216 possible values. The first-octet Group and Local bits for this exact prefix are both zero; changing either bit produces a different prefix. Possible suffix values are not a device or shipment count.
About this vendor.
A MAC address beginning 00:0C:61 identifies an IEEE MA-L assignment to AC Tech corporation DBA Advanced Digital; the supplied records do not identify a device or product using it. The assignment is evidence of registry allocation, not proof of who currently operates a device or where it is deployed.
This is a 24-bit prefix match: compare the address’s first three octets with 00:0C:61. The remaining 24 bits allow 16,777,216 possible suffix values. That is a mathematical range, not a count of devices or shipments.
For this prefix, the first octet is 00; its Group bit and Local bit are both zero. Those values are fixed for an exact match. Setting either bit changes the prefix and does not describe variation within this assignment. RFC 7042 explains the significance of these bits in MAC identifiers. The IEEE CSV record gives the country as the United States but provides no assignment date.
