ADOIR Digital Technology — device or product identification is Unknown
Summary
- // what this is
- ADOIR Digital Technology is registered to MAC prefix
00:05:EFin the IEEE OUI database. When a device's MAC address begins with00:05:EF, that block was registered by ADOIR Digital Technology — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- A MAC address matching the first 24 bits of 00:05:EF is consistent with this MA-L registry assignment. The first-byte Group and Local bits are both zero. The 24 remaining bits allow 16,777,216 possible suffix values; that is not a device or shipment count. A prefix match does not establish a particular device, product, current legal identity, or security state.
About this vendor.
A MAC address beginning with 00:05:EF identifies an IEEE MA-L assignment to ADOIR Digital Technology; the available evidence does not identify a device class or product associated with it. This assignment is a registry fact, not evidence that a particular device is deployed under the prefix or that the company currently holds the same identity.
00:05:EF is a 24-bit prefix, leaving 24 bits for suffix values. That allows 16,777,216 possible suffix values; it is not a count of devices or shipments. In this prefix, the first octet’s Group bit (01) and Local bit (02) are both zero. RFC 7042 describes these bit positions and their significance in MAC addresses; the supplied excerpt does not include the full definitions.
For identification, compare the first three octets exactly, then treat a match as evidence of the registry assignment only.
