PFU LIMITED MAC Prefixes: Registry Assignment Identified

A MAC address beginning with 00:80:17 or F0:BC:C9 matches an IEEE MA-L assignment registered to PFU LIMITED; the prefix alone does not identify a device type or prove who currently operates it. IEEE’s CSV records show two 24-bit prefixes, each leaving 24 bits for a possible suffix. Each therefore has 16,777,216 possible suffix values, which is a mathematical address space, not a count of devices or shipments.

RFC 7042 explains that the Group and Local bits are in the first octet. For both assigned prefixes, those bits are zero: 00 has both clear, and F0 (11110000) has both clear. A captured address matches either assignment only when its first 24 bits match the complete prefix. Changing either bit changes the prefix; these fixed bits do not describe variation within the assignment.

PFU describes its work as document imaging products and services, including image scanners, and IT infrastructure construction and support. Its catalog also includes embedded computers, security and document management software and services, and multi-vendor services. PFU said it joined the Ricoh Group in 2022; its 2023 release described scanner rebranding under the Ricoh brand. No cited source maps these products or categories to either prefix, so a prefix match cannot identify a specific product.
