Adaptix, Inc. MAC prefix: vendor assignment, device unknown
Summary
- // what this is
- Adaptix is registered to MAC prefix
00:12:61in the IEEE OUI database. When a device's MAC address begins with00:12:61, that block was registered by Adaptix — the OUI identifies the maker of the network hardware, which is not always the brand on the device. Adaptix was acquired; the registration remains on record with IEEE. - // analyst note
- The IEEE assignment maps to Adaptix, Inc.; no supplied evidence maps the prefix to a device category or a specific product.
About this vendor.
A MAC address beginning 00:12:61 matches an IEEE assignment to Adaptix, Inc.; the available evidence does not identify a device category for this prefix. A matching prefix establishes the registry assignment, not which device, operating system, or company currently uses the address.
This is a 24-bit prefix, so the match is limited to the first three octets; the remaining 24 bits allow 16,777,216 possible suffix values. That is a mathematical range, not a count of devices or shipments. RFC 7042 describes MAC identifiers as using an initial OUI or a longer assigned prefix, followed by remaining identifier bits.
The IEEE record fixes both the Group bit and Local bit at zero for this literal prefix. Changing either bit changes the prefix and does not describe variation within this assignment. Company filings describe Adaptix’s work in broadband wireless technology, including OFDMA and MIMO. A 2012 release reports that an Acacia Research subsidiary acquired Adaptix, but neither source maps these technologies or products to 00:12:61.
- Device category
- Unknown; no supplied source maps a device category to this exact prefix.
- MAC prefix
00:12:61(24 bits; first three octets must match).- Possible suffix values
- 16,777,216 values across the remaining 24 bits; this is not a device or shipment count.
