Adtec Corporation MAC Prefix: Vendor Identified, Device Unknown
Summary
- // what this is
- Adtec is registered to MAC prefix
00:02:29in the IEEE OUI database. When a device's MAC address begins with00:02:29, that block was registered by Adtec — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- This 24-bit prefix fixes the first three octets; 24 suffix bits permit 16,777,216 values, not an observed device or shipment count. For the exact prefix, the first-octet Group and Local bits are both zero. Changing either bit changes the prefix. A match identifies a registry assignment, not a specific device or current operator.
About this vendor.
A MAC address beginning 00:02:29 matches an IEEE MA-L assignment to Adtec Corporation; the available records do not identify a device type or product for this prefix. The assignment identifies the registered organization associated with the prefix, not a particular device, its current operator, or its safety.
This is a 24-bit prefix, so matching requires the first three octets to be 00:02:29. The remaining 24 bits allow 16,777,216 possible suffix values. That is a mathematical range, not a count of devices, shipments, or observed addresses.
The first octet is 00 in hexadecimal. Its Group bit and Local bit are both zero, as the supplied RFC guidance describes for the assigned prefix. Those bits are fixed in an exact 00:02:29 match; changing either produces a different prefix. IEEE assignment dates are unavailable in the supplied CSV records.
