Leviton Manufacturing Co., Inc. — 2 prefixes (MA-L)

Leviton Manufacturing Co., Inc. holds two confirmed IEEE MA-L (24-bit) blocks under that exact registered name — 00:07:A6 (New Orleans, LA) and 00:1E:C6 (Tualatin, OR) — with a punctuation-only variance between the two registry rows (one carries a trailing period, one does not) that reflects the same organization, not two companies. A third, adjacent OUI, 00:05:2F, is registered to a distinctly-named entity, "Leviton Network Solutions" of Bothell, WA; because the org string differs from "Leviton Manufacturing Co., Inc.," it was excluded from this vendor slug and is flagged here only as a probable related/sister registration. Beyond the bare registrations, Leviton shows verifiable company substance: it currently ships Decora Smart Wi-Fi switches and dimmers (Matter/Alexa/Google/Apple Home compatible, with a user-facing MAC-lookup support article), a Network Solutions division selling structured copper/fiber cabling for data centers (expanded via the 2021 Berk-Tek acquisition), commercial wireless lighting controls and occupancy sensors, and AcquiSuite/Energy Monitoring Hub submetering appliances — the last of which is the subject of a 2025 CISA ICS advisory.

IEEE assignments

00:07:A6 → "Leviton Manufacturing Co., Inc." (New Orleans, LA); 00:1E:C6 → "Leviton Manufacturing Co., Inc" (Tualatin, OR) [Confirmed] — IEEE MA-L, the IEEE MA-L registry, :38398

Registry / block size

MA-L (24-bit) only; no MA-M or MA-S blocks found for any Leviton org variant in the official IEEE registries [Confirmed] — the IEEE MA-M registry, the IEEE MA-S registry (checked, no match)

Org name variance

the two blocks differ only by a trailing period in the registry string ("Co., Inc." vs "Co., Inc"); treated as the same organization [Confirmed] — the IEEE MA-L registry, :38398

Related but excluded org

00:05:2F → "Leviton Network Solutions", 2222 222nd Street S.E., Bothell, WA 98021 — a differently-named registrant, not folded into this entry [Confirmed exists / Likely related] — the IEEE MA-L registry

Possible MA-S block (unconfirmed)

a third-party "the Wireshark manufacturer database"-style database lists 00:50:C2:30:E0/36 as Leviton, but this block does NOT appear in the official IEEE MA-S file (the IEEE MA-S registry) checked for this entry — treated as an unverified conflict, not recorded as confirmed

[Unknown] — the IEEE MA-S registry (no match); web angle citing a generic "the Wireshark manufacturer database file"

Dates

no assignment/registration date is published by IEEE for any of the three Leviton-family rows; correctly left null, not sourced from third-party "date registered" scrapes [Confirmed] — the IEEE MA-L registry

Security context

CISA ICS advisory ICSA-25-198-01 (CVE-2025-6185) — reflected XSS in Leviton AcquiSuite and Energy Monitoring Hub submetering appliances; no known public exploitation reported to CISA. Advisory identifier and product scope confirmed via CISA ICS advisory listing; the specific CVSS base score is not asserted here (search-snippet sourcing only; a numeric figure is omitted rather than published unverified)

Analyst note

two confirmed MA-L blocks plus multiple currently-shipping, IP-connected product lines and a CISA advisory clear the abstain-on-shells bar — this is not a bare single-OUI registration.
