ADB Italia — 2 prefixes (MA-L)

A MAC address beginning with 10:5A:F7 or 8C:59:C3 was assigned by IEEE to a registrant recorded as "ADB Italia," based at Viale Sarca 222 in Milan, Italy. That address is shared with the separate, already-verified registrant "ADB Broadband Italia" (24 prefixes), which independently traces to ADB Global, an active telecom-equipment maker of broadband gateways and pay-TV set-top boxes. Hardware carrying either prefix is therefore likely, though not independently confirmed, ADB-family equipment.

IEEE's cached registry (the IEEE MA-L registry) lists exactly two MA-L blocks for the org-name string "ADB Italia" (the source field carries a trailing space): 10:5A:F7 and 8C:59:C3. Both rows are byte-identical in registrant name and address, with none of the transcription anomalies — bogus ZIP codes, stray text, mismatched country — found on some rows of the sibling "ADB Broadband Italia" registration. No MA-M or MA-S block was found for this org string.

Whether "ADB Italia" is the same legal entity as "ADB Broadband Italia" is not documented outright; a Dun & Bradstreet search snippet places an "ADB ITALIA SRL" on the same street (telecom-equipment production, incorporated 2004), but the source page itself errored on direct fetch, so this rests on a snippet, not a primary-source read. A same-named Italian directory listing was checked and excluded — it resolved to an unrelated tire retailer at that address.

No CVE names "ADB Italia" directly. One NVD-confirmed flaw, CVE-2018-13110, affects the broader ADB Global gateway line (Epicentro platform, models DV2210, P.RG AV4202N, VV2220, VV5522) but isn't confirmed to trace to either of these two prefixes specifically. Most web hits for "ADB" plus a vulnerability keyword concern the unrelated Android Debug Bridge tool (e.g. CVE-2026-0073) and must not be attributed to this vendor.

IEEE assignment

2 MA-L prefixes → "ADB Italia" (trailing space in source), registered Milan, Italy [Confirmed] — the IEEE MA-L registry 105AF7, 8C59C3

Registry / block size

MA-L (24-bit OUI) only; no MA-M or MA-S blocks found for this org string [Confirmed] — the IEEE MA-L registry, the IEEE MA-M registry, the IEEE MA-S registry (no matches)

Registered address

Viale Sarca 222, 20126 Milano, IT — identical on both rows, no anomalies [Confirmed] — the IEEE MA-L registry

Registration/assignment date

Unknown — IEEE's the IEEE MA-L registry has no date column (header: Registry, Assignment, Organization Name, Organization Address) [Confirmed] — the IEEE MA-L registry

Third-party date-artifact caveat

maclookup.app shows "first registration 16 March 2016" for 8C:59:C3 and "last updated 17 November 2016" for 10:5A:F7; these are database-scrape artifacts, not IEEE facts, and are not recorded as this entry's registration date [Confirmed] — https://maclookup.app/vendors/adb-italia

IANA Reference

not applicable — this is an IEEE MAC-vendor (OUI) registration, not an IANA protocol-registry assignment

Company identity

not independently documented as a standalone entity; the registered address matches the already-verified sibling registrant "ADB Broadband Italia," which traces to ADB Global (Advanced Digital Broadcast), an active telecom-equipment maker founded 1995, now HQ'd in Bellevue, Switzerland

[Likely] — /mac/vendor/adb-broadband-italia/, https://www.adbglobal.com/our-history/

Company identity (secondary signal)

a Dun & Bradstreet search snippet for "ADB ITALIA SRL" places it on the same street (telecommunications-equipment production/wholesale, ~25 employees, incorporated 2004); the source page itself returned an error on direct fetch, so this is snippet-only corroboration, not a primary-source read [Likely] — https://www.dnb.com/business-directory/company-profiles.adb_italia_srl.0425aec818bee2615f5dcc985a3082a1.html (search-snippet only; page errors on direct fetch)

Sources checked and excluded

an Italian business-directory listing for a same-named entity resolved to an unrelated tire retailer at that address; a Northdata page mixed a French SIREN registry identifier with this Italian address — both excluded as unreliable, not cited as fact

Device types corroborated

broadband gateway/router (DSL-fiber CPE) and pay-TV/IPTV set-top box — family-level corroboration via the ADB Global product line and the sibling entry; not confirmed to trace to these 2 specific prefixes [Likely] — /mac/vendor/adb-broadband-italia/, https://nvd.nist.gov/vuln/detail/CVE-2018-13110

Security context

CVE-2018-13110 (NVD, published 2018-07-06, CVSSv3 7.5 HIGH) is a privilege-escalation flaw in ADB Global broadband gateways (Epicentro platform; models DV2210, P.RG AV4202N, VV2220, VV5522) — corporate-family-level context, not confirmed against these 2 specific prefixes; no advisory names "ADB Italia" directly as of an August 2026 search [Confirmed CVE exists; Likely relevance to this registrant] — https://nvd.nist.gov/vuln/detail/CVE-2018-13110

Term-collision caution

most web/CVE search results for "ADB" plus a vulnerability keyword concern the unrelated Android Debug Bridge tool (e.g. CVE-2026-0073, a wireless-ADB auth-bypass affecting Android 14-16) and must not be attributed to this vendor

Related vendors

ADB Broadband Italia (same Milan address, separate 24-prefix registration, already DONE); ADB — Advanced Digital Broadcast SA, Switzerland (separate OUI set, vendor-adb); Advanced Digital Broadcast (Taiwan entity, 1 prefix, vendor-advanced-digital-broadcast) — no prefix overlap with any of the three

[Confirmed no overlap] — /mac/vendor/adb/, /mac/vendor/adb-broadband-italia/, /mac/vendor/advanced-digital-broadcast/

Analyst note

two confirmed OUI blocks plus a same-address match to a verified real company are enough substance to finalize this entry, but the "ADB Italia" ↔ "ADB Global" corporate link itself rests on an address match and a snippet-only business-directory read, not a document that states the relationship outright — treat device, product, and security claims here as family-level, not prefix-confirmed
