Flex (formerly Flextronics) is a major global EMS/contract manufacturer, and its MAC footprint is spread across several national IEEE registrant entities that should be aliased to one family: "Flextronics International Kft" (Hungary; ~26 blocks; holds MA-L, MA-M, and MA-S), "Flextronics International GmbH & Co. Nfg. KG" (Germany/Austria), "Flextronics Computing(Suzhou)Co.,Ltd." and "FLEXTRONICS MANUFACTURING(ZHUHAI)CO.,LTD." (China), and "Flextronics Canafa Design Services." The group HQ is in Singapore, while the registrants span Europe and China. These OUIs appear across a broad range of devices Flex assembles for other brands — networking, consumer electronics, medical, automotive, aerospace/defense, industrial, and IoT. Flextronics renamed to Flex Ltd. in 2015, and both names persist as registrant strings. Like Foxconn, a Flex OUI identifies the EMS/manufacturer rather than the brand on the box. For triage, a Flex/Flextronics OUI means "built by Flex for a customer," so classify the device by its behavior rather than the OUI.
- IEEE assignment
- many national entities — "Flextronics International Kft" (Hungary, ~26), "Flextronics International GmbH & Co. Nfg. KG", "Flextronics Computing(Suzhou)Co.,Ltd.", "FLEXTRONICS MANUFACTURING(ZHUHAI)CO.,LTD.", "Flextronics Canafa Design Services" [Confirmed] — IEEE MA-L/MA-M/MA-S
- Registry / block size
- MA-L, MA-M, and MA-S all appear (the Kft entity alone holds all three) [Confirmed] — maclookup.app (IEEE-sourced)
- HQ / country
- group HQ Singapore; registrants in Hungary, Germany/Austria, and Suzhou & Zhuhai, China [Confirmed] — maclookup.app
- Company status
- active; Flextronics renamed to Flex Ltd. in 2015 (both names persist as registrant strings) [Likely] — netify.ai
- Device types
- networking, consumer electronics, medical, automotive, aerospace/defense, industrial, IoT [Confirmed] — maclookup.app
- Notable products
- contract-assembled devices across many industries
- Verified prefix(es)
- 14:0D:4F, C8:C6:4A, 08:BB:3C [Confirmed] — IEEE oui.csv
- Special note
- Like Foxconn, a Flex OUI identifies the EMS/manufacturer, not the brand on the box. The Flextronics→Flex (2015) rename means both names appear as registrant strings. The IEEE registry publishes no assignment dates, so none is stated here. [Confirmed]
- Related vendors
- none (diversified EMS)
- Analyst note
- A Flex/Flextronics OUI means "built by Flex for a customer" — classify by device behavior, not OUI.
