MediaTek holds about 4 MA-L blocks registered as "MediaTek Inc" at Dusing 1st Rd., Hsinchu Science Park, Hsinchu City, Taiwan, with the legacy Ralink Technology blocks tracked separately. Verified samples include 00:0A:00, 00:0C:43, 00:0C:E7, and 00:17:A5 — and note that 00:0C:43 still carries a Wireshark "Ralink Technology, Corp." note reflecting the legacy lineage. These OUIs appear on Wi-Fi/Bluetooth chipsets (routers, APs, smart TVs, IoT), mobile SoCs (the Dimensity and Helio families, found in countless Android phones and tablets), smart-TV SoCs, and broadband chipsets. MediaTek acquired Ralink Technology via a share swap that was expected to take effect on 1 October 2011 (Bloomberg valued the deal at roughly NT$18.2 billion / ~US$616 million), so "Ralink" is a separate legacy registrant absorbed in 2011. The key analyst point is the chipset pattern: a MediaTek OUI identifies a device built on MediaTek silicon regardless of brand — the same chipset-OUI flag as Broadcom, Qualcomm, or Realtek. For triage, a MediaTek OUI often means the radio or SoC is MediaTek while the device could be any brand of router, TV, or phone, so cross-reference other signals to identify the actual product.

- Special note
- A MediaTek OUI is a chipset-OUI flag — it identifies devices built on MediaTek silicon regardless of brand. Ralink (Wi-Fi) is a separate legacy registrant absorbed in 2011. The IEEE registry publishes no assignment dates, so none is stated here. [Confirmed]
