TP-Link Technologies — 174 (China entity) + 87 (TP-Link Systems Inc) = 261 prefixes (MA-L)

TP-Link's IEEE footprint spans two registrant strings that both normalize to the "TP-Link" brand: the legacy/primary "TP-LINK TECHNOLOGIES CO.,LTD." (174 MA-L blocks, Shenzhen, Guangdong, CN) and the newer "TP-Link Systems Inc" (87 MA-L blocks, Irvine, CA, US) created by the company's 2024 corporate restructuring, in which TP-Link Global and TP-Link USA merged into TP-Link Systems Inc as the US/global parent, distinct from the China entity. All 261 assignments are MA-L (24-bit OUI); no MA-M or MA-S entries exist for the brand. These prefixes appear across TP-Link's consumer and SMB range — Archer and Deco routers/mesh, Omada SMB switching and access points, the Kasa and Tapo smart-home lines, VIGI/Tapo cameras, and Mercusys — with newer devices increasingly carrying the TP-Link Systems Inc blocks. Two analyst points matter. First, a TP-Link OUI on a managed corporate network frequently signals an employee-introduced consumer router/AP 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, so the OUI reliably identifies TP-Link hardware. Second, as of June 2026 TP-Link carries significant US regulatory and security context: a March 2026 FCC order banning new imports of the affected foreign-produced routers (existing deployed devices are not recalled), a June 2026 DoD addition to its Chinese-military-linked entities list, Texas state-device bans and a state AG lawsuit, and a high-volume, active CVE record spanning routers, cameras, and switches — relevant when assessing TP-Link gear discovered in an inventory.

IEEE assignment

174 prefixes → TP-LINK TECHNOLOGIES CO.,LTD. (Shenzhen, CN); 87 → TP-Link Systems Inc (Irvine, CA, US); 261 MA-L blocks total [Confirmed] — IEEE MA-L

Registry / block size

MA-L only (24-bit OUI). China entity 174 blocks, TP-Link Systems Inc 87 blocks, 261 total (counted from cached the IEEE MA-L registry). No MA-M (the IEEE MA-M registry) or MA-S (the IEEE MA-S registry) entries for any TP-Link registrant string [Confirmed] — IEEE MA-L. NOTE: IEEE's public OUI data publishes NO assignment/registration date (the IEEE MA-L registry columns are only Registry, Assignment, Organization Name, Organization Address); any "date registered" on third-party tools is a database artifact, not an IEEE fact.

HQ / country

Building 24 & 28, Central Science and Technology Park, Shennan Road, Nanshan, Shenzhen, Guangdong 518057, CN (legacy/China entity registry address; older blocks list Honghualing and Pingshandayuan campus variants); TP-Link Systems Inc predominantly at 10 Mauchly, Irvine, CA, US 92618 (earlier blocks: 5 Peters Canyon Rd, Irvine; plus HK and SG address variants)

Security / regulatory context (as of June 2026)

active, high-volume CVE record across routers (Archer AX/AXE/BE, TL-WR series), Tapo cameras, and Omada switches — classes include authenticated/unauthenticated command injection, authorization bypass, stack-based buffer overflow, and DoS via UPnP/HTTPD/firmware-update endpoints. US actions: March 2026 FCC order banning new imports of affected foreign-produced routers (no recall of deployed units); June 2026 DoD added TP-Link to Chinese-military-linked entities list; Texas state-device ban (Jan 2026) and state AG deceptive-marketing lawsuit (Feb 2026) [Confirmed] — tp-link.com/us/press/security-advisory, fcc.gov NSD-Routers0326, en.wikipedia.org/wiki/TP-Link, app.opencve.io, cvedetails.com/vendor/11936

Global scale (vendor self-reported)

Special note

Two registrant strings should both be normalized to "TP-Link"; newer devices increasingly carry the "TP-Link Systems Inc" OUIs [Confirmed] — IEEE MA-L

Related vendors

TP-Link Systems Inc (US/global parent) and TP-LINK TECHNOLOGIES CO.,LTD. (China entity) — same brand family; Mercusys (TP-Link sub-brand)

Analyst note

A TP-Link OUI on a corporate network often signals an employee-introduced consumer router/AP or smart-home gadget — a common shadow-IT and rogue-AP finding; weigh the June-2026 US import-ban/military-entity-list context when assessing discovered TP-Link gear.
