Blink by Amazon — 5 prefixes (MA-L)

A MAC address beginning with 70:AD:43, 74:13:48, F0:74:C1, 74:AB:93, or 3C:A0:70 belongs to Blink, the Amazon-owned smart home security camera brand — typically seen on Blink's indoor/outdoor cameras, video doorbells, or the Sync Module hub that bridges them to Wi-Fi.

Blink began as an independent company (legal entity Immedia Semiconductor, Inc.) and became "Blink, An Amazon Company" after Amazon's December 2017 acquisition; the registry name "Blink by Amazon" and the legacy Immedia legal string both trace to that lineage. The org holds five distinct MA-L blocks, all registered to the same North Reading, MA address, with no MA-M/MA-S blocks found under this name.

Product coverage is concrete: Blink Outdoor 2K+, Blink Mini 2K+, Blink Indoor, Blink Video Doorbell, Blink Arc, and the Blink Home Monitor App with Alexa integration. Confirmed independently by both the official site and a third-party privacy review, which also notes Blink is cloud-dependent by default and has a documented CVE history in older camera firmware.

IEEE assignment

5 MA-L prefixes → "Blink by Amazon" (Immedia Semiconductor, Inc. or its affiliates), registered 100 Riverpark Drive, North Reading, MA, US 01864 [Confirmed] — the IEEE MA-L registry (local IEEE-derived cache), cross-checked against https://maclookup.app/vendors/blink-by-amazon (matching all 5 prefixes)

Registry / block size

MA-L (24-bit OUI) x5 blocks; no MA-M/MA-S blocks found for this org — a similarly-named "Blink Services AB" (Sweden) sits in the unrelated MA-S table and "EBlink" (France) in MA-M [Confirmed] — the IEEE MA-S registry, the IEEE MA-M registry

Registration dates

no IEEE-published assignment date exists for any of the 5 blocks; third-party crawl dates shown on maclookup.app (spanning 2020-04-09 through 2026-04-02) are database index timestamps, not IEEE facts, and are not recorded here

[Confirmed absence / dates left Unknown] — IEEE publishes no OUI assignment dates; https://maclookup.app/vendors/blink-by-amazon

Security/privacy context

cloud-dependent by default (video routes to AWS-hosted Blink cloud unless a local Sync Module is used); vendor claims AES-256 at rest and TLS in transit; disclosed CVE history in Blink XT2 firmware including a sync-module command-injection flaw, patched at firmware >=2.13.11 [Likely — CVE coverage is several years old and not re-verified against current firmware] — https://threatpost.com/amazon-blink-smart-camera-flaws/150962/, https://cisomag.com/amazons-blink-smart-security-cameras-vulnerable-to-attacks/

Unrelated namesake caution

joinblink.com (employee-communications SaaS) is a distinct company also branded "Blink," unrelated to this OUI registrant [Confirmed] — web research pass, no citation needed (absence of registry overlap)

Related vendors

Amazon.com, Inc. (parent; may hold separate OUI registrations under its own name, not covered by this entry) [Likely] — inferred from acquisition history
