Panasonic Corporation AVC Networks Company — 7 prefixes (MA-L)

Panasonic Corporation AVC Networks Company is a networking- and AV-equipment-focused division of Panasonic, registered to seven distinct MA-L (24-bit) OUI blocks in the IEEE registry: 00:1B:D3, 04:20:9A, 20:C6:EB, 70:58:12, 8C:C1:21, A8:13:74, and CC:7E:E7. All seven share the same registered address (1-15 Matsuo-cho, Kadoma, Osaka, Japan 571-8504), with only minor punctuation and capitalization differences across rows — a pattern consistent with one organization registering multiple blocks over time rather than seven unrelated companies. The division's product lines historically cover network/IP security cameras, network video recorders (NVRs), and AV/communication encoders and decoders; the surveillance line has since been rebranded under Panasonic's i-PRO spinoff, which continues to publish security advisories referencing this legacy hardware lineage, including CVE-2025-36513 (a CSRF issue affecting WV-series camera models) and CVE-2025-32730 (a hardcoded encryption key in the i-PRO Configuration Tool). No CVE record ties directly to a specific OUI prefix — vulnerability disclosures attach to firmware and model numbers, not MAC address blocks — so that linkage stays unverified. IEEE's public OUI registry publishes no assignment or registration date for any of the seven blocks; third-party aggregator "date registered" values, where present, are database artifacts rather than IEEE facts and are excluded from this entry's dated fields. A direct fetch of the raw IEEE oui.txt registry was blocked (HTTP 418) during this research session, so the prefix list here is cross-checked against a third-party aggregator rather than independently re-derived from the live IEEE source.

IEEE assignment

7 MA-L prefixes → "Panasonic Corporation AVC Networks Company" [Confirmed] — the IEEE MA-L registry (cached IEEE MA-L listing)

Registry / block size

MA-L (24-bit OUI); 7 confirmed blocks, 0 MA-M / 0 MA-S (oui36) blocks under this exact org name [Confirmed] — the IEEE MA-L registry, the IEEE MA-M registry, the IEEE MA-S registry

Registered address

1-15 Matsuo-cho, Kadoma, Osaka, JP 571-8504 (minor punctuation/capitalization variants across rows) [Confirmed] — the IEEE MA-L registry

Verified prefixes (all MA-L, same org name)

00:1B:D3, 04:20:9A, 20:C6:EB, 70:58:12, 8C:C1:21, A8:13:74, CC:7E:E7 [Confirmed] — the IEEE MA-L registry

Company substance

identifiable Panasonic business division (not a bare single-OUI registration), corroborated by 7 same-name OUI assignments plus documented corporate/product context [Likely] — https://maclookup.app/vendors/panasonic-corporation-avc-networks-company, https://holdings.panasonic/global/corporate/investors/pdf/20140917_presentation_e.pdf

Device types

network/IP security cameras, NVRs, AV/communication encoders and decoders; surveillance line later rebranded under the i-PRO spinoff [Likely] — https://security.panasonic.com/products/wv-v1330l1/, https://i-pro.com/products_and_solutions/en/surveillance/solutions/technologies/cyber-security/psirt/security-advisories

Security context

documented CVEs for this product lineage (CVE-2025-36513 CSRF on WV-series cameras; CVE-2025-32730 hardcoded encryption key in i-PRO Configuration Tool); no CVE ties to a specific OUI/MAC prefix, that linkage is Unknown [Likely] — https://i-pro.com/products_and_solutions/en/surveillance/solutions/technologies/cyber-security/psirt/security-advisories, https://holdings.panasonic/global/corporate/product-security/psirt/advisories.html

Date registered

Unknown for all 7 blocks — IEEE's public OUI data (the IEEE MA-L registry columns: Registry, Assignment, Organization Name, Organization Address) carries no date field; a third-party aggregator's per-prefix "registration date" is a database artifact, not an IEEE fact, and is not attributed here

[Confirmed absence] — the IEEE MA-L registry, https://maclookup.app/vendors/panasonic-corporation-avc-networks-company

IEEE direct verification

Unknown — a direct fetch of standards-oui.ieee.org/oui/oui.txt returned HTTP 418 (blocked) this session; the prefix list is corroborated via the cached local registry copy plus a third-party aggregator cross-check rather than a live independent IEEE re-fetch
