ADATA Technology Co., Ltd MAC Prefix Identification
Summary
- // what this is
- ADATA Technology is registered to MAC prefix
70:7C:18in the IEEE OUI database. When a device's MAC address begins with70:7C:18, that block was registered by ADATA Technology — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- The exact 24-bit prefix has first-octet Group and Local bits both 0, leaving 24 suffix bits (16,777,216 possible values); this is a mathematical address-space count, not a device or shipment count. A captured address matching this prefix supports the recorded registry assignment only.
About this vendor.
A MAC address beginning 70:7C:18 matches an IEEE MA-L assignment registered to ADATA Technology Co., Ltd; the supplied evidence does not identify a specific device category or product for this prefix. A prefix match shows the assignment recorded for those initial bits, not the identity, deployment, or safety of a particular device.
This is one 24-bit prefix, leaving 24 bits (16,777,216 possible suffix values) in a 48-bit address. That number describes possible suffix values, not observed devices or shipments. For this exact prefix, the first-octet Group bit and Local bit are both zero. Changing either bit produces a different prefix; it does not describe variation within the fixed 70:7C:18 assignment.
RFC 7042 describes 48-bit MAC identifiers as an assigned initial prefix followed by additional bits, and explains the Group and Local bits. The IEEE CSV record supplies the legal organization name and MA-L assignment. Assignment dates are unavailable in these IEEE CSV records.
