NEC Magnus Communications, Ltd. — 3 prefixes (MA-L)

A MAC address starting with 00:14:79, 00:60:DC, or CC:B6:91 belongs to NEC Magnus Communications, Ltd., a Japanese communications-equipment maker whose product lines include CATV headend and set-top-box systems, optical and power-line-carrier transmission gear, and automated ticketing and currency-handling machines used at transit systems and venues.

The company traces to a 1985 founding as Nippon Electric Techno-Marketing Co., Ltd., later renamed NEC Magnus Communications. It has been a wholly-owned subsidiary of NEC Networks & System Integration Corporation (NESIC) since 2013, placing it inside the broader NEC Corporation group rather than standing as an independent brand.

IEEE's public registry lists three distinct MA-L (24-bit) OUI blocks under this name: 00:14:79 and 00:60:DC as "NEC Magnus Communications,Ltd." (Tokyo and Yokohama addresses respectively), and CC:B6:91 as "NECMagnusCommunications" — a one-word spelling variant at a separate Tokyo address, most likely the same legal entity rather than a distinct company. No MA-M or MA-S sub-allocations were found under either spelling.

A CVE search for the company surfaced CVE-2023-30258, a critical unauthenticated command-injection flaw — but that bug belongs to "MagnusBilling," an unrelated open-source VoIP/Asterisk billing application from a different vendor (MagnusSolution). The overlap is name coincidence only; no relationship between the two entities was found, and the CVE must not be attributed to NEC Magnus Communications hardware.

Analyst note

Three MA-L blocks across two Tokyo addresses and one Yokohama address, a 40-year operating history, a named 2013 parent acquisition, and concrete named product lines together indicate a substantive, identifiable company rather than a bare single-OUI registration.
