Panasonic Communications Co., Ltd. — 3 prefixes (MA-L)

A MAC address beginning with 00:80:F0, 08:00:23, or BC:C3:42 belongs to Panasonic Communications Co., Ltd., a Panasonic division registered in Fukuoka, Japan, historically associated with business fax machines, SIP/IP telephones, IP-PBX systems, and network (IP) cameras.

All three blocks are MA-L (24-bit) assignments in the IEEE registry, each carrying the same registered address — 4-1-62 Minoshima, Hakata-ku, Fukuoka city, Fukuoka, JP 812-8531 — with only minor wording differences between rows (one row drops "-ku" and "city"). Three same-name registrations at one address is stronger evidence of an identifiable, ongoing organization than a single bare OUI.

That same Fukuoka building address also appears on three present-day "Panasonic Connect Co., Ltd." blocks (B8:20:8E, 4C:36:4E, BC:3E:0B) in the same registry file, consistent with Panasonic Connect being this entity's successor at that site. Secondary company-directory sources separately describe a rename to "Panasonic System Networks Co., Ltd.," but no primary Panasonic source directly confirms that chain, so the rename itself stays Likely rather than Confirmed.

No CVE record is attributed to "Panasonic Communications Co., Ltd." by name in NVD, CVEDetails, or OpenCVE as of an August 2026 search. A Log4j advisory (CVE-2021-44228) is published on the current Panasonic Connect support site for Panasonic SIP phones — a plausible continuation of this entity's IP-telephone line — but it names no MAC prefix or legal entity, so tying it to these three blocks specifically is Unknown.

IEEE's public OUI registry (the IEEE MA-L registry: Registry, Assignment, Organization Name, Organization Address) publishes no assignment or registration date for any of the three blocks. Third-party aggregator "date registered" values for these prefixes are database artifacts, not IEEE facts, and are excluded from this entry's dated fields.

Registered address

4-1-62 Minoshima, Hakata-ku, Fukuoka city, Fukuoka, JP 812-8531 (the 080023 and 0080F0 rows omit "-ku"/"city") [Confirmed] — the IEEE MA-L registry

Company substance

3 same-name MA-L assignments sharing one address, plus that address also matching present-day Panasonic Connect Co., Ltd. rows (B8:20:8E, 4C:36:4E, BC:3E:0B) in the same registry file, and independent third-party corroboration of the same 3-prefix count

business fax machines / multi-function printers, SIP/IP telephones, IP-PBX systems, network (IP) cameras [Likely] — https://docs.connect.panasonic.com/pcc/support/fax/, https://docs.connect.panasonic.com/pcc/support/sipphone/, https://security.panasonic.com/products_technology/products/ip_camera_network_camera/

Corporate history / rename

secondary company-directory sources state Panasonic Communications Co., Ltd. was later renamed Panasonic System Networks Co., Ltd.; a UK subsidiary listing separately shows "Panasonic Communications Company (U.K.) Ltd." feeding into "Panasonic System Networks Company U.K. Limited." No primary Panasonic source was directly readable to confirm this chain [Likely] — https://system.privco.com/company/panasonic-system-networks-company-uk-limited, https://www.asmag.com/suppliers/companyinfo.aspx?co=panasonic

Security context

no CVE record attributed to "Panasonic Communications Co., Ltd." by name in NVD/CVEDetails/OpenCVE as of an August 2026 search; a Log4j advisory (CVE-2021-44228) for Panasonic SIP phones exists on the current Panasonic Connect support site but names no MAC/OUI prefix or legal entity, so the tie to these 3 blocks is Unknown [Confirmed for the absence; Unknown for the lineage tie] — https://www.cvedetails.com/vendor/8409/Panasonic.html, https://app.opencve.io/cve/?vendor=panasonic, https://docs.connect.panasonic.com/pcc/support/sipphone/disposaldoc-Apache_Log4j_Vulnerability.html

Malware association

none found as of an August 2026 search [Unknown] — (no source found either way)

Date registered

Unknown for all 3 blocks — IEEE's public OUI data (the IEEE MA-L registry columns: Registry, Assignment, Organization Name, Organization Address) carries no date field; third-party aggregator "date registered" values are database artifacts, not IEEE facts, and are not attributed here
