00:80:27in the IEEE OUI database. When a device's MAC address begins with00:80:27, that block was registered by Adaptive Systems — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- A prefix match identifies a registry assignment, not a particular device, operating system, current legal identity, or security state.
About this vendor.
A MAC address beginning 00:80:27 matches an IEEE MA-L assignment to ADAPTIVE SYSTEMS, INC.; the record does not identify a device category or product using it. The prefix is 24 bits, leaving 24 bits for possible suffix values. A match establishes the address prefix only, not the specific device, its maker today, or its security state.
The first byte of 00:80:27 is 00, so the Group bit and Local bit are both zero. In RFC 7042, the Group bit distinguishes group from individual addresses; the supplied excerpt does not explain the Local bit. These bit values describe the prefix and do not show how frequently an address is deployed.
There are 16,777,216 possible 24-bit suffix values. That is the size of the suffix space, not a count of devices, shipments, or observed addresses. Assignment dates are unavailable in these IEEE CSV records.
