Sony Home Entertainment & Sound Products Inc — 3 prefixes (MA-L)

A MAC address starting with 14:3F:A6, 94:DB:56, or 38:18:4C belongs to Sony Home Entertainment & Sound Products Inc, a Sony Group business unit that made TV and home-audio hardware, and is typically seen on Sony consumer electronics such as Bravia televisions and soundbars.

All three prefixes are direct MA-L grants to the identical registrant name and Tokyo address in the IEEE registry — not sub-allocations of a shared IEEE base, so identification against these three specific blocks is reliable. A fourth, related registration (6C:B2:27, Sony Video & Sound Products Inc) shares the same address and is likely a predecessor or sibling entity, though no primary source confirms the exact corporate relationship.

The entity itself was formed 2019-04-01 from a merger of Sony Visual Products Inc. and Sony Video & Sound Products Inc., per a GSMArena news report corroborated by a Sony-affiliate retailer announcement (the latter reachable only via search snippet, direct fetch 403'd). It was later folded back into Sony Electronics Corporation / Sony Corporation in a subsequent reorganization; sources disagree on whether that happened in 2020 or 2021, so the exact date is Unknown.

No source ties a specific captured device to any of these three prefixes — the TV/home-audio device-class attribution is inferred from the entity's documented business scope, not from a device sighting, and should not be upgraded past Likely. No CVEs, vulnerable-firmware reports, or abuse associations were found for this vendor or these prefixes.

Registration dates

Unknown — IEEE's public OUI data (the IEEE MA-L registry: Registry, Assignment, Organization Name, Organization Address) publishes no date field. Third-party lookup sites showed per-prefix "registered" dates (14:3F:A6 → 2020-10-29; 38:18:4C → 2019-04-22; 94:DB:56 → 2020-01-10) but these are database artifacts, not IEEE facts, and are not asserted as registration dates here.

Security/abuse notes

Analyst note

These three prefixes are direct, non-shared MA-L grants to one named Sony entity, so identification against 14:3F:A6, 94:DB:56, and 38:18:4C specifically is reliable; the device-class call (TV/home-audio) is a scope inference, not a confirmed sighting, and should not be over-stated in downstream copy.
