D-Link International — 60 prefixes (MA-L), Singapore registrant

"D-Link International" is one of several separately-registered IEEE registrants in the D-Link corporate family, and it is a distinct legal entity from "D-Link Corporation" (Taipei, Taiwan), "D-Link Systems, Inc." (Irvine, CA), "D-Link Middle East FZCO" (Dubai), and the two Shanghai entities. In the cached IEEE MA-L registry it holds 60 assignments (~1.0 billion addresses) under the org string exactly "D-Link International", all pointing at the Singapore address 1 International Business Park, #03-12 The Synergy, Singapore 609917. No MA-M or MA-S blocks are registered under this exact org name. These OUIs surface on the same consumer/SMB gear the D-Link brand is known for — routers, switches, wireless access points, mydlink IP cameras, and DNS-series NAS — sold through D-Link's international distribution arm. For triage, a D-Link OUI on a corporate network can flag an unsanctioned consumer router, AP, or camera, and the brand's recurring default-credential and legacy-EOL exposure pattern makes such devices worth investigating as shadow IT.

IEEE assignment

60 prefixes → D-Link International, registered Singapore [Confirmed] — IEEE MA-L

Registry / block size

MA-L only (24-bit OUI); 60 IEEE prefixes (~1.0B addresses); no MA-M/MA-S under this exact org name [Confirmed] — IEEE MA-L (the IEEE MA-L registry / the IEEE MA-M registry / the IEEE MA-S registry). 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" (e.g. maclookup.app's "January 5, 2010") is a third-party database artifact, not an IEEE fact.

HQ / country

1 International Business Park, #03-12 The Synergy, Singapore 609917, SG (registry address) [Confirmed] — IEEE MA-L. One outlier record (OUI C8D3A3) lists country code "US" instead of "SG"; treated as a source data-entry error, same Singapore registrant.

Company status

active (part of the active D-Link brand) [Confirmed] — dlink.com

Device types

Registration date

Unknown / not applicable — IEEE publishes no OUI registration dates; no date column exists in the registry CSVs. Third-party "date registered" figures are database artifacts and are not recorded. [Confirmed] — IEEE the IEEE MA-L registry

IANA reference

Not applicable / blank — IANA Reference is not a field for IEEE OUI/MA-L assignments [Confirmed]

Security / analyst note

D-Link consumer/SMB devices as a brand have a documented, ongoing pattern of default-credential and legacy-EOL security issues (e.g. hardcoded Telnet creds, IMEI-derived default admin passwords, DNSChanger-style config hijacks, Mirai-variant botnet targeting of legacy routers). These are brand-wide, not confirmed as isolated to International-registered prefix blocks. A D-Link OUI on a corporate network warrants scrutiny as possible shadow IT.
