Airsonics MAC Prefix 3C:78:73: assignment documented

Primary prefix
3C:78:73
Block
MA-L

Summary

// what this is
Airsonics is registered to MAC prefix 3C:78:73 in the IEEE OUI database. When a device's MAC address begins with 3C:78:73, that block was registered by Airsonics — the OUI identifies the maker of the network hardware, which is not always the brand on the device.
// analyst note
This MA-L prefix has a 24-bit match boundary and 24 suffix bits (16,777,216 possible suffix values). For the exact prefix, the first-byte Group and Local bits are both zero. A matching prefix establishes the registry assignment, not a specific device or shipment count; RFC 7042 describes MAC address prefix and bit interpretation.

A MAC address beginning 3C:78:73 matches an IEEE MA-L assignment to Airsonics; the available evidence does not identify a specific device from that prefix. The assignment record does not establish which devices use it or whether it appears in observed traffic.

A separate catalog page describes the AirSonics DeskPod Tri6 as a desktop device with Wi-Fi 6, 2.4, 5, and 6 GHz radios, two Ethernet ports, and Bridge and Router modes. It lists OpenSync 6.4 certification. The catalog does not map this product to the prefix, so those specifications are product context rather than a prefix identification.

The assignment is 24 bits long, leaving 24 bits for suffix values: 16,777,216 possible values, not a count of devices or shipments. For this exact prefix, the first-byte Group bit is 0 and the Local bit is 0. In an observed address, a match through the first 24 bits identifies the assigned prefix; the remaining 24 bits distinguish addresses within that boundary. RFC 7042 explains the address structure and these bit meanings.
