VIZIO holds about 16 MA-L blocks registered as "Vizio, Inc" at 39 Tesla, Irvine, CA. Verified samples include C4:1C:FF, A0:6A:44, 2C:64:1F, 3C:9B:D6, 00:BD:3E, E8:38:A0, and CC:95:D7. These OUIs appear on smart TVs (the SmartCast platform), soundbars, and streaming hardware. VIZIO was acquired by Walmart — announced 20 February 2024 and closed 3 December 2024 (~$2.3 billion, ~$11.50/share); VIZIO became a wholly-owned Walmart subsidiary and was delisted from the NYSE. A factual privacy note relevant to device identification: VIZIO's business includes significant automatic content recognition (ACR) data collection, and on 6 February 2017 VIZIO agreed to pay $2.2M to settle FTC and New Jersey charges that it collected ACR viewing data from 11 million smart TVs without consent. Walmart's stated rationale for the acquisition centers on SmartCast ACR data for its Walmart Connect advertising business. For triage, a VIZIO OUI is a smart TV or soundbar (extremely common in the US); given the ACR data history, treat it as a privacy/egress-relevant consumer AV device on managed networks and segment from corporate assets.
