Aclima, Inc. MAC Prefix: Registered Vendor, Device Unknown
Summary
- // what this is
- Aclima is registered to MAC prefix
6C:57:79in the IEEE OUI database. When a device's MAC address begins with6C:57:79, that block was registered by Aclima — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- A MAC beginning 6C:57:79 matches this MA-L registry assignment. The 24-bit prefix leaves 24 suffix bits, or 16,777,216 possible suffix values. For this literal prefix, the first-byte Group bit (0x01) and Local bit (0x02) are both zero; changing either produces a different prefix. A prefix match does not identify a device, product, deployment, or security state.
About this vendor.
A MAC address beginning 6C:57:79 matches an IEEE MA-L assignment registered to Aclima, Inc.; the record does not identify a device type. The assignment covers a 24-bit prefix, leaving 24 bits for suffix values. There are 16,777,216 possible suffix values, but that number is not a device, shipment, or observed-use count.
For this exact prefix, the first octet is 6C. Its Group bit (0x01) and Local bit (0x02) are both zero, as indicated by the prefix arithmetic. Those bits are fixed for a literal match to 6C:57:79; changing either bit produces a different prefix. RFC 7042 describes these bits’ significance in MAC identifiers and explains that IEEE assignments may use an initial prefix followed by additional bits.
A captured address with this prefix supports a match to the registry assignment only. It does not establish a particular product, deployment, traffic prevalence, current corporate identity, or security status. The supplied records contain no MA-M or MA-S assignment for this entity, and give no assignment dates.
