Adura Technologies MAC prefix: vendor identified, device unknown
Summary
- // what this is
- Adura Technologies is registered to MAC prefix
00:27:0Bin the IEEE OUI database. When a device's MAC address begins with00:27:0B, that block was registered by Adura Technologies — the OUI identifies the maker of the network hardware, which is not always the brand on the device.
About this vendor.
A MAC address beginning 00:27:0B matches the IEEE MA-L assignment to Adura Technologies; the record does not identify a device or product. The assignment names the registry holder, but a prefix match cannot establish which device made a captured address or whether the address reflects current vendor identity.
00:27:0B is a 24-bit prefix, leaving 24 bits for suffix values. The IEEE record lists one assignment and provides no assignment date. Possible suffix values describe the address space, not a count of devices or shipments.
RFC 7042 explains that the first-octet Group and Local bits are meaningful for MAC addresses. For this exact prefix, both are zero: the Group bit is 0 and the Local bit is 0. Matching this assignment requires the first 24 bits to equal 00:27:0B; toggling either bit changes the prefix and no longer matches this literal assignment.
