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

A MAC address beginning with 00:19:87, 54:CD:10, or D8:B1:2A belongs to Panasonic Mobile Communications Co.,Ltd., historically Panasonic's dedicated mobile-handset subsidiary, typically seen on Japanese-market feature phones and, later, Android-based smartphones rather than general Panasonic consumer electronics.

All three blocks are standalone MA-L (24-bit) assignments in the IEEE registry, each registered to the same organization name and the same Yokohama address — 600 Saedo-cho, Tsuzuki-ku, Yokohama City, Kanagawa Prefecture, JP 224-8539 — with only minor wording variants between rows (comma placement, "Prefecture" present or dropped). Three same-name registrations at one address is stronger evidence of an identifiable, ongoing organization than a single bare OUI, and none of the three prefixes appear as a sub-allocation base in the IEEE MA-M registry or the IEEE MA-S registry, so each is a full block this registrant holds outright rather than a slice of an IEEE-shared base.

The subsidiary's documented product line spans Japanese-carrier feature phones sold under NTT DoCoMo, au, and SoftBank (the "P-series," including early-1990s handsets), earlier GSM-era devices, and a 2012 return to international markets with the Android-based "Eluga" smartphone line. This is device-type corroboration by company history and product line, not a per-MAC device capture, so it is tagged Likely rather than Confirmed.

Corporate lineage after roughly 2013 is unresolved: one source describes an absorption into Panasonic Corporation effective April 1, 2013, with the mobile-handset and mobile-base-station businesses split beforehand, while a separate secondary source shows a same-named entity founded 2013-04-01 and merged into Panasonic Connect Co., Ltd. in 2022 — possibly a distinct later entity, possibly a database artifact. Neither chain is confirmed against a primary Panasonic filing, so post-2013 status stays Unknown.

No CVE, malware, or fingerprinting association specific to "Panasonic Mobile Communications" (as distinct from Panasonic generally) was found as of an August 2026 search. 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 "date registered" values are database artifacts, not IEEE facts.

Corporate history / lineage

reported absorption into Panasonic Corporation effective ~April 1, 2013 (mobile-handset and mobile-base-station businesses split beforehand); a separate source describes a same-named entity founded 2013-04-01 and merged into Panasonic Connect Co., Ltd. in 2022 — the two chains conflict and neither is confirmed against a primary Panasonic filing
