Airo Wireless MAC Prefix C4:26:28 — Device Unknown

Primary prefix
C4:26:28
Block
MA-L

Summary

// what this is
Airo Wireless is registered to MAC prefix C4:26:28 in the IEEE OUI database. When a device's MAC address begins with C4:26:28, that block was registered by Airo Wireless — the OUI identifies the maker of the network hardware, which is not always the brand on the device.
// analyst note
C4:26:28 is a 24-bit prefix in a 48-bit MAC address, leaving 24 suffix bits and 16,777,216 possible suffix values. For this exact prefix, the first-byte Group and Local bits are both zero; changing either bit yields a different prefix. Possible suffix values are not a device or shipment count. RFC 7042 describes the Group and Local bits in MAC addresses. A match indicates the registry assignment and does not identify a particular device, product, deployment, or security state.

A MAC address beginning C4:26:28 is registered to Airo Wireless, but the available records do not identify a device type or product associated with this prefix. A prefix match establishes the registry assignment only; it does not establish who deployed a captured address or whether it is in use.

The IEEE MA-L record lists one assignment, C4:26:28, for Airo Wireless. Its country indication is US. Assignment dates are unavailable in these IEEE CSV records.

This is a 24-bit prefix in a 48-bit address, leaving 24 suffix bits and 16,777,216 possible suffix values. That number describes the address space available under the prefix, not a count of devices or shipments. The first-byte Group and Local bits are both zero for this exact prefix. Changing either bit produces a different prefix; it does not describe variation within this fixed assignment. RFC 7042 explains the significance of these bits in MAC addresses.
