MAC address vendor

Wyze Labs, Inc. — 6 prefixes (5 MA-L + 1 MA-M)

Primary prefix
D0:3F:27
Block
MA-L
Status
Active

Summary

// what this is
Wyze Labs is registered to MAC prefix D0:3F:27 and 5 more in the IEEE OUI database. When a device's MAC address begins with D0:3F:27, that block was registered by Wyze Labs — the OUI identifies the maker of the network hardware, which is not always the brand on the device.
// analyst note
Six independent IEEE assignments (5 MA-L + 1 MA-M sub-block) corroborate an active, growing hardware manufacturer rather than a single opportunistic registration; this clears the OUI-vendor abstention bar and should be treated as a legitimate consolidated vendor entry, not a thin shell.

About this vendor.

Updated  ·  Confidence: High

A MAC address beginning with D0:3F:27, F0:C8:8B, 80:48:2C, 7C:78:B2, or 2C:AA:8E — or falling inside the 28-bit block A4:DA:22:2 — belongs to Wyze Labs, Inc., typically seen on WyzeCam WiFi security cameras, video doorbells, smart locks, and other smart-home hardware.

Wyze Labs is a Kirkland/Bothell, Washington-based consumer IoT company founded in 2017 by former Amazon employees. It built its reputation on low-cost WiFi cameras and has since expanded into video doorbells, smart locks, lighting, thermostats, and robot vacuums, all documented on its official site and Wikipedia entry.

Five of Wyze's assignments are full MA-L (24-bit) blocks. The sixth is an MA-M (28-bit) sub-allocation, A4:DA:22:2, carved out of A4:DA:22 — a shared base registered to the IEEE Registration Authority itself and used by many unrelated MA-M holders. Only the A4:DA:22:2 sub-block is Wyze's; the bare A4:DA:22 prefix must never be attributed to Wyze.

IEEE's public OUI registry publishes no assignment or registration date for any of these blocks. Third-party aggregators such as maclookup.app display per-prefix "registered" dates, but those are database first-seen timestamps, not IEEE facts, and should not be cited as such.

Two documented security incidents are worth noting for devices carrying these prefixes: a February 2024 outage exposed camera thumbnails and event data to roughly 13,000 unrelated users, and Bitdefender-disclosed camera vulnerabilities from March 2019 went unpatched until January 2022 — useful context for firmware-hygiene guidance.

IEEE assignment
5 MA-L prefixes (D0:3F:27, F0:C8:8B, 80:48:2C, 7C:78:B2, 2C:AA:8E) + 1 MA-M sub-block (A4:DA:22:2/28) → Wyze Labs Inc [Confirmed] — IEEE the IEEE MA-L registry (5 entries), IEEE the IEEE MA-M registry (1 entry)
Registry / block size
5x MA-L (24-bit OUI) + 1x MA-M (28-bit sub-allocation); 6 assignments total. The MA-M block is A4:DA:22:2, sitting under the shared IEEE Registration Authority base A4:DA:22 — the bare 24-bit A4:DA:22 belongs to the IEEE Registration Authority and hosts many unrelated MA-M holders, so it must not be presented as a Wyze prefix [Confirmed] — IEEE the IEEE MA-L registry, the IEEE MA-M registry. NOTE: IEEE's public OUI data publishes NO assignment/registration date; any "date registered" on third-party tools (e.g. maclookup.app) is a database artifact, not an IEEE fact.

Special note
Two documented security incidents affect devices on these prefixes — a Feb 16, 2024 outage/breach that exposed camera thumbnails/event data to ~13,000 unrelated users (1,504 tapped through to view images, some viewed video), and Bitdefender-disclosed camera vulnerabilities (March 2019) that went unpatched until January 2022
