TP-Link's OUIs span two registrant strings that should both be normalized to "TP-Link": the legacy/primary "TP-LINK TECHNOLOGIES CO.,LTD." (~174 blocks) based in Shenzhen, and the newer "TP-Link Systems Inc" (~87 blocks, Irvine, CA) reflecting the company's 2024 corporate restructuring — TP-Link Global and TP-Link USA merged to form TP-Link Systems Inc as the parent overseeing international offices, distinct from the China entity. All registrations are MA-L. These OUIs appear across TP-Link's consumer and SMB range: Archer routers, Deco mesh systems, Omada SMB switching and access points, and the Kasa and Tapo smart-home lines. Newer devices increasingly carry the "TP-Link Systems Inc" blocks. The most useful analyst insight is contextual: a TP-Link OUI on a corporate network often signals an employee-introduced consumer router or access point, or a smart-home gadget — a common shadow-IT and rogue-AP finding worth flagging on managed VLANs. The brand maps cleanly to the device maker (no chipset-vs-brand ambiguity), so the OUI itself reliably identifies TP-Link hardware.
