Suzuken Co., Ltd. — 2 prefixes (MA-L)
Summary
- // what this is
- Suzuken is registered to MAC prefix
00:1A:C9and 1 more in the IEEE OUI database. When a device's MAC address begins with00:1A:C9, that block was registered by Suzuken — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- A Suzuken OUI most plausibly identifies internal/proprietary logistics or RFID-tracking hardware rather than a retail networking product; Suzuken is not a consumer network-equipment brand.
About this vendor.
Suzuken Co., Ltd. is a large, publicly traded Japanese pharmaceutical and healthcare wholesale distributor headquartered in Nagoya, Aichi Prefecture, founded in 1932 and listed on the Tokyo Stock Exchange (ticker 9987). The cached IEEE MA-L registry contains two distinct OUI blocks under the Suzuken name: 00:1A:C9, registered as "SUZUKEN CO.,LTD" at the Suzuken Tomei Building in Nagoya, and D8:43:ED, registered simply as "Suzuken" at a separate Higashi-ku, Nagoya address. Both registered addresses sit within Suzuken's home city and correspond to plausible corporate or logistics facilities, which is why this entry treats the two blocks as one company holding two OUI assignments rather than two unrelated same-named registrants. Suzuken operates one of Japan's largest pharmaceutical wholesale networks, serving hospitals, clinics, and community pharmacies, and also runs its own retail pharmacy chain plus an in-house logistics and RFID-based drug-traceability system ("Cubixx") rolled out since 2017. No public source ties either OUI to a specific named device model; the most plausible use is internal logistics, warehouse-handheld, or RFID/IoT cabinet hardware tied to that traceability system, but that link is inference, not a sourced fact. No CVEs, security advisories, or abuse-database findings were located tied to either prefix.

- Same-company disambiguation
- both registry addresses fall within Nagoya, Suzuken's home city, consistent with one company holding two OUI blocks rather than two unrelated "Suzuken" registrants; not confirmed via a corporate filing that names both blocks together[Likely] — the IEEE MA-L registry, https://www.suzuken.co.jp/en/business/oroshi.html
- Device / product context
- no source found that names either OUI as identifying a specific device model; plausible internal logistics/RFID hardware tied to Suzuken's Cubixx drug-traceability system (deployed since 2017) is an inference, not sourced [Unknown]
- Security context
- no CVEs, advisories, or abuse-database findings located tied to either prefix [Unknown]
- Date fields
- IEEE's public OUI/MA-L registry publishes no assignment/registration date for either block; third-party site maclookup.app shows database timestamps (2006/2015 for 00:1A:C9, 2017 for D8:43:ED) that are that site's own database artifacts, not IEEE facts, and are not recorded as registration dates here[Confirmed] — https://maclookup.app/macaddress/001AC9, https://maclookup.app/macaddress/D843ED
- Related registry check
- no match for "suzuken" in the cached MA-S (the IEEE MA-S registry) registry; neither block is an MA-S assignment [Confirmed] — the IEEE MA-S registry
