Summary

// what this is
ADB Broadband Italia is registered to MAC prefix A0:4F:D4 and 23 more in the IEEE OUI database. When a device's MAC address begins with A0:4F:D4, that block was registered by ADB Broadband Italia — the OUI identifies the maker of the network hardware, which is not always the brand on the device.

About this vendor.

Updated  ·  Confidence: Medium

ADB Broadband Italia is the Italian legal and manufacturing entity behind ADB — Advanced Digital Broadcast, later rebranded ADB Global — a telecom-equipment maker founded in 1995 that designs pay-TV set-top boxes and broadband residential gateways, now headquartered in Bellevue, Switzerland, with a long operating history in Italy and Poland. The cached IEEE registry (the IEEE MA-L registry) lists 24 distinct MA-L (24-bit) OUI blocks assigned to this exact organization name, all registered to a Milan address on Viale/Via Sarca (either number 222 or 336, postal code 20126) — no MA-M (the IEEE MA-M registry) or MA-S (the IEEE MA-S registry) blocks were found, so the registry class is MA-L only. Holding 24 separate prefixes is itself a substance signal: a shell registrant rarely burns that many blocks. Corroborating that substance, the vendor's own corporate site (adbglobal.com) describes current gateway hardware lines (Thunder7, ThunderAX) and an epiCentro middleware platform deployed on tens of millions of devices, while Italian ISPs including Fastweb and WINDTRE Business have documented ADB-branded CPE (VV4820 Fastweb Fibra VDSL2/fiber gateway, VV2222 ADSL2+VoIP modem, DV2200/DV2211 modems, VM5722) in their own support material. Wikipedia and industry press further corroborate ADB's set-top-box history, including a 2003 Italian digital-terrestrial STB launch tied to the RAI HDTV pilot. The registry data itself carries a few registrant-side anomalies worth flagging rather than silently correcting: one row shows a bogus duplicate postal code ("12345"), one has stray text ("pisacataway") appended to the address, and one lists country "US" despite a Milano street address — all present verbatim in IEEE's own published the IEEE MA-L registry, not introduced by this lookup. IEEE's registry publishes no assignment/registration date field at all, so no date is recorded for any of these 24 prefixes; third-party aggregators (maclookup.app, macaddress.io) show a "registered 1998 / updated 2019" style date, but that is a database-scrape artifact, not an IEEE fact, and is not carried into this entry.

IEEE assignment
24 MA-L prefixes → "ADB Broadband Italia", registered Milano, Italy [Confirmed] — the IEEE MA-L registry
Registry / block size
MA-L (24-bit OUI) only; no MA-M or MA-S blocks found for this org [Confirmed] — the IEEE MA-L registry, the IEEE MA-M registry, the IEEE MA-S registry (no matches)
Registered address
Viale/Via Sarca 222 or 336, 20126 Milano, IT (address string varies row to row in the registry, same physical location) [Confirmed] — the IEEE MA-L registry
Registry data anomalies (verbatim in source, not corrected)
one row carries a duplicate/bogus ZIP "12345"; one row has stray text "pisacataway" appended; one row lists country "US" despite the Milano street address [Confirmed] — the IEEE MA-L registry
Registration/assignment date
Unknown — IEEE's the IEEE MA-L registry has no date column (header is Registry, Assignment, Organization Name, Organization Address); no date is fabricated for this vendor [Confirmed] — the IEEE MA-L registry
IANA Reference
not applicable — this is an IEEE MAC-vendor registration, not an IANA protocol registry assignment
Company identity
ADB / Advanced Digital Broadcast (later ADB Global), founded 1995, pay-TV set-top-box and broadband-gateway maker, now HQ'd in Bellevue, Switzerland, with historical Italy/Poland operations [Confirmed] — adbglobal.com, en.wikipedia.org/wiki/Advanced_Digital_Broadcast
Company status
active (current product lines Thunder7, ThunderAX gateways; epiCentro middleware) [Confirmed] — https://www.adbglobal.com/broadband-gateways/, https://www.adbglobal.com/our-history/
Device types corroborated
DSL/fiber broadband gateways and routers (Fastweb VV4820, VV2222, DV2200/DV2211, WINDTRE VM5722) and pay-TV/IPTV set-top boxes (ADB-1761WF and earlier DTT-era units) [Confirmed] — https://www.fastweb.it/myfastweb/assistenza/guide/adb-dv2200/, https://www.windtrebusiness.it/supporto/servizi-e-configurazioni/adb-vm5722
Security context
no vendor-specific CVE or advisory surfaced for "ADB Broadband Italia" branded devices in this pass; only generic CPE/IPTV-STB risk-class commentary (default credentials, exposed management interfaces) appears on router-default-password aggregator sites, which is not a sourced vulnerability finding [Likely — generic class only, not vendor-specific] — https://www.router-reset.com/default-password-ip-list/ADB
Third-party date-artifact caveat
maclookup.app / macaddress.io show a "registered 1998 / updated 2019" style date; this is a database-scrape artifact, not an IEEE-published fact, and is intentionally not recorded as this entry's registration date
[Confirmed] — https://maclookup.app/vendors/adb-broadband-italia, https://macaddress.io/statistics/company/1942
