Adonit Corp. Ltd. — F4:6A:BC (MA-L)

Adonit Corp. Ltd. holds the MA-L block F4:6A:BC, registered to a Taipei, Taiwan address (Rm. A, 9F, No.107 Sec.4 Ren-Ai Rd.). Adonit is a privately held consumer-electronics company founded in 2010 — its Kickstarter-launched Jot stylus line put it on the map — with dual presence in Austin, Texas and Taipei; the OUI registration name "Adonit Corp. Ltd." is the Taiwan-registered legal entity. The hardware behind this block is consumer stylus pens: capacitive and active Bluetooth styluses for iPad, Android, and Windows Surface touchscreens, plus more recent USB-C wired styluses. The Bluetooth product lineage runs back to the Jot Touch (2012), an early pressure-sensitive Bluetooth stylus. Independent corroboration that Adonit ships Bluetooth radio hardware comes from the FCC: grant ZCC-J10008 covers a Bluetooth stylus operating 2402–2480 MHz at roughly 0.5 mW conducted power (authorized 2016-10-18, tested by TÜV Rheinland Taiwan). For asset-classification work, a device presenting F4:6A:BC on a globally-administered address is genuine Adonit hardware; the usual MA-L caveats apply (a per-prefix "date registered" on third-party tools is a database artifact, not an IEEE fact). No Adonit-specific CVEs or public security advisories were found; general BLE privacy considerations (peripheral tracking via persistent Bluetooth addresses) apply to any BLE stylus but nothing Adonit-attributed is documented as of June 2026.

IEEE assignment

F4:6A:BC → Adonit Corp. Ltd. [Confirmed] — IEEE MA-L (row MA-L,F46ABC,Adonit Corp. Ltd.), corroborated by https://maclookup.app/vendors/adonit-corp-ltd

Registry / block size

MA-L (24-bit OUI) [Confirmed] — IEEE MA-L; present only in the IEEE MA-L registry (not the IEEE MA-M registry/MA-M, not the IEEE MA-S registry/MA-S). 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); maclookup.app's "First Seen 2013-07-29 / Last Modified 2015-11-17" are third-party database artifacts, not IEEE facts.

FCC corroboration

FCC ID ZCC-J10008 — Bluetooth stylus, 2402–2480 MHz, ~0.5 mW conducted, authorized 2016-10-18, tested by TÜV Rheinland Taiwan Ltd. Confirms Adonit ships Bluetooth radio hardware. [Confirmed] — https://fccid.io/ZCC-J10008

Allocated date

Unknown — IEEE publishes no OUI registration date; left null (no fabrication) [Unknown]

Security context

no Adonit-specific CVEs or advisories found; general BLE peripheral-tracking privacy risk applies to any BLE stylus but nothing Adonit-attributed is documented as of June 2026 [Confirmed (absence-of-evidence, not a guarantee)] — https://fccid.io/ZCC-J10008, https://en.wikipedia.org/wiki/Adonit

Analyst note

F4:6A:BC on a globally-administered address = genuine Adonit hardware; OUI alone won't see Wi-Fi devices that present randomized/locally-administered MACs, and absence of the prefix doesn't prove "not Adonit." Sole MA-L block registered to this entity per third-party lookup.
