Alcatel Canada Inc. MAC Prefix: Vendor Identified, Device Unknown
Summary
- // what this is
- Alcatel Canada is registered to MAC prefix
00:80:21in the IEEE OUI database. When a device's MAC address begins with00:80:21, that block was registered by Alcatel Canada — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- The 24-bit prefix fixes the first three octets, leaving a 24-bit suffix with 16,777,216 possible values; this is not a count of devices or shipments. For this literal prefix, the first-byte Group and Local bits are both zero; changing either bit yields a different prefix. A prefix match establishes registry assignment only, not a particular device or current operator.
About this vendor.
A MAC address beginning 00:80:21 matches an IEEE MA-L assignment to Alcatel Canada Inc.; the record does not identify a device category or product for the address. A prefix match establishes the registry assignment, not a specific device, its software, or who currently operates it.
This 24-bit prefix fixes the first three octets, leaving 24 bits for the suffix. That allows 16,777,216 possible suffix values; it does not indicate how many devices were made, shipped, or observed. For this literal prefix, the first-byte Group bit and Local bit are both zero. Changing either bit produces a different prefix and is not variation within this assignment.
RFC 7042 describes 48-bit MAC identifiers as an assigned prefix followed by additional bits, and explains the Group and Local bit meanings. The available IEEE row gives no assignment date. No product catalog or other first-party company material is supplied to establish industry, products, website, or company status.
