VXi Corporation — 2 prefixes (MA-L)

VXi Corporation holds two MA-L (24-bit OUI) blocks — 00:25:52 and 3C:68:16 — both registered to the same IEEE address, 271 Locust Street, Dover NH 03820, US. VXi was a professional-headset maker founded in 1989 in Dover, NH (later operating out of Lowell, MA) whose hardware embeds these OUIs: Bluetooth and DECT wireless headsets aimed at contact centers, unified-communications/office deployments, and high-noise mobile work such as trucking and fleet. The flagship lines are BlueParrott (mobile/high-noise) and VXi-branded UC/contact-center headsets; confirmed products on these prefixes include the BlueParrott B450-XT Bluetooth headset, the V200 DECT wireless headset system, and the Reveal Pro Office Bluetooth headset. These are audio peripherals, not networking gear — Bluetooth units carry a BT device address derived from the OUI and DECT base stations expose a standard Ethernet OUI on their USB/host interface. In October 2016, GN Audio A/S (GN Group / Jabra) acquired VXi and BlueParrott for roughly USD 35 million; VXi no longer operates independently, the BlueParrott brand survives under GN, and vxicorp.com now redirects (HTTP 301) to blueparrott.com. The Dover, NH address in the IEEE record is the original company location and is now closed. No CVEs or public vulnerabilities specific to VXi/BlueParrott products were found; the relevant risk surface is the generic one for professional Bluetooth audio peripherals (BT pairing attack classes such as BLUFFS/BIAS, and microphone exposure in sensitive environments), with no named advisory targeting these OUI prefixes.

IEEE assignment

2 prefixes → VXi Corporation, registered Dover, NH, US [Confirmed] — IEEE MA-L

Registry / block size

MA-L (24-bit OUI) for both 00:25:52 and 3C:68:16; no MA-M or MA-S assignments exist in the cached registries [Confirmed] — 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; any "date registered" on third-party tools is a database artifact, not an IEEE fact.

Analyst note

a globally-administered 00:25:52 or 3C:68:16 address identifies genuine VXi/BlueParrott audio hardware (now a GN/Jabra brand); these are headset peripherals, so expect them on Bluetooth/DECT/USB endpoints, not on switches or routers.
