D-Link's MAC footprint spans three IEEE registrants that should be unified in the pipeline: "D-Link Corporation" (about 27 MA-L blocks, ~453M addresses; Taipei, Taiwan), "D-Link International" (Singapore), and "D-Link （Shanghai）Limited Corp." — the last of which introduces MA-M blocks alongside MA-L. The verified sample prefixes below all sit under "D-Link Corporation" specifically. These OUIs appear on consumer/SMB routers, switches, wireless access points, IP cameras (mydlink), and NAS. D-Link is extremely common in consumer/SOHO settings worldwide. For triage, a D-Link OUI on a corporate network may signal an unsanctioned consumer router, access point, or camera — a common shadow-IT finding worth investigating.
- IEEE assignment
- ~27 prefixes → D-Link Corporation (Taipei); plus D-Link International (Singapore) and D-Link （Shanghai）Limited Corp. [Confirmed] — IEEE MA-L
- Registry / block size
- MA-L (D-Link Corporation); D-Link （Shanghai） adds MA-M; ~27 blocks under D-Link Corporation (~453M); last updated 2025-11-26 (maclookup.app API 'updated' field) [Confirmed] — maclookup.app (IEEE-derived). NOTE: IEEE's public OUI data publishes NO assignment/registration date (oui.csv columns are only Registry, Assignment, Organization Name, Organization Address); any "first registered" date from third-party tools is a database artifact, not an IEEE fact.

- Special note
- Three registrant entities (Corporation / International / Shanghai) — unify them in enrichment; the Shanghai entity introduces MA-M blocks. The sample prefixes above belong to "D-Link Corporation" specifically; keep "D-Link International" and "D-Link （Shanghai）Limited Corp." backed by their own prefixes rather than assuming these samples belong to them.

- D-Link International, D-Link （Shanghai）Limited Corp.
- Analyst note
- Extremely common in consumer/SOHO settings; a D-Link OUI on a corporate network may signal an unsanctioned consumer router/AP/camera (shadow IT).
