AGOS Co.,Ltd — one MA-L prefix assigned; device identity unknown
Summary
- // what this is
- AGOS is registered to MAC prefix
74:C6:4Ain the IEEE OUI database. When a device's MAC address begins with74:C6:4A, that block was registered by AGOS — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- A literal match to 74:C6:4A fixes the first-octet Group and Local bits at 0. This 24-bit prefix leaves 24 suffix bits, or 16,777,216 possible suffix values; that is not an observed device or shipment count. A prefix match establishes the registry assignment only.
About this vendor.
A MAC address beginning 74:C6:4A matches an IEEE MA-L assignment to AGOS Co.,Ltd; the supplied evidence does not identify a device type or product using it. This prefix identifies the registry assignment, not a particular device, current vendor identity, or security state.
The assignment is 24 bits long, leaving 24 bits for suffix values: 16,777,216 possible values. That is a mathematical range, not a count of devices or shipments. An address captured in traffic can establish a prefix match, but cannot by itself identify the specific product or prove who deployed it.
For this exact prefix, the first octet 74 has Group bit 0 and Local bit 0. The Group and Local bits are fixed for a literal 74:C6:4A prefix match; changing either bit produces a different prefix. RFC 7042 describes the significance of these MAC address bits and the structure of 48-bit identifiers.
