Air-Weigh Incorporated: MAC Prefix Identifies the Registry Assignee
Summary
- // what this is
- Air-Weigh is registered to MAC prefix
00:39:69in the IEEE OUI database. When a device's MAC address begins with00:39:69, that block was registered by Air-Weigh — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- A prefix match identifies the registry assignment only. The 24-bit suffix space has 16,777,216 possible values; this does not indicate actual devices or deployments. The first octet 00 has Group and Local bits both zero; changing either bit changes the exact prefix.
About this vendor.
A MAC address beginning with 00:39:69 matches an IEEE MA-L assignment to Air-Weigh Incorporated; the available evidence does not identify a device category or a particular product for this prefix.
The assignment covers the first 24 bits of a 48-bit MAC address. The remaining 24 bits allow 16,777,216 possible suffix values, but that is a mathematical address-space count, not a count of devices, shipments, or addresses in use.
In 00:39:69, the first octet is 00. The supplied excerpt from RFC 7042 identifies the Group bit (01) and Local bit (02) as significant in MAC addresses, and says the Group bit is unspecified when OUIs and longer MAC prefixes are assigned. The registry lists 00:39:69 as an MA-L assignment to Air-Weigh Incorporated. This prefix match establishes the registry assignment only; it does not establish a device, deployment, current vendor identity, or security status.
