Alcatel-Lucent Telecom Limited: MAC prefix identification
Summary
- // what this is
- Alcatel-Lucent Telecom is registered to MAC prefix
F8:30:94in the IEEE OUI database. When a device's MAC address begins withF8:30:94, that block was registered by Alcatel-Lucent Telecom — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- A match to F8:30:94 identifies the first 24 bits of an address as matching the MA-L registry assignment. For this prefix, the first-octet Group and Local bits are both 0. The remaining 24 bits have 16,777,216 possible suffix values; this is address-space capacity, not an observed device or shipment count. Registry matching does not establish a device model, deployment, or security state.
About this vendor.
A MAC address beginning F8:30:94 matches an IEEE MA-L assignment registered to Alcatel-Lucent Telecom Limited. That identifies the registry holder recorded for the prefix; it does not establish which vendor made the device, what device it is, or whether the address is in use.
The assignment is 24 bits long, leaving 24 bits for the remaining address. Under the supplied address interpretation, the first octet F8 has Group bit 0 and Local bit 0. The matching boundary is the first three octets: a different value in any of those octets does not match this MA-L prefix. RFC 7042 explains that MAC prefixes can be followed by the remaining bits to form a 48-bit identifier and describes the Group and Local bits.
There are 16,777,216 possible values for the 24-bit suffix. That is a mathematical address-space count, not a count of devices, shipments, or observed traffic. The supplied IEEE records do not include assignment dates.
- What a match establishes
- The first 24 bits match the IEEE assignment; it does not identify a particular device or its deployment.
- Address bits
- For this prefix, Group bit = 0 and Local bit = 0.
- Suffix space
- 24 remaining bits allow 16,777,216 possible suffix values; this is not a device count.
