Thomson Telecom Belgium — 9 prefixes (MA-L)

Thomson Telecom Belgium is the Edegem (Antwerp), Belgium-registered CPE manufacturing arm behind the Thomson "Speedtouch" and Technicolor "TG"-series residential DSL/VDSL/cable gateways — the ADSL2+/VDSL2 modem-routers with built-in VoIP and the DOCSIS cable modems that ISPs across Europe and North America bundled with broadband service through the 2000s and 2010s. The entity's registration footprint is unusually large for a single-country subsidiary: nine distinct IEEE MA-L blocks, all tied to the same organization name and street address, versus the single-block norm for most vendors. That multi-block footprint, combined with a decade-plus paper trail of user manuals, retailer listings, and CVE history, distinguishes this from a bare shell registration. Parent company Thomson SA rebranded to Technicolor in 2010, and the Belgian CPE unit's product lines continued under Technicolor branding before the connected-home business was ultimately spun off and rebranded Vantiva in 2023–2024 — meaning the legal entity behind these OUIs has almost certainly changed name/ownership since the blocks were first assigned, even though the hardware and OUIs remain in active field use. A neighboring prefix, 00:07:C3, is registered to the plain org name "Thomson" and is NOT part of this Belgian entity's block set; it is excluded here to avoid conflating two related-but-distinct IEEE registrations.

IEEE assignment

9 distinct MA-L blocks registered to "Thomson Telecom Belgium" [Confirmed] — https://services13.ieee.org/RST/standards-ra-web/rest/assignments/?registry=MA-L&text=Thomson+Telecom+Belgium

Prefixes (all MA-L)

00:0E:50, 00:14:7F, 00:18:F6, 00:1D:68, 00:1F:9F, 00:24:17, 00:26:44, 00:90:D0, 08:76:FF [Confirmed] — the IEEE MA-L registry (local cache, cross-checked against IEEE REST API)

Registered address / country

Prins Boudewijnlaan 47, B-2650 Edegem, Antwerp, Belgium [Confirmed] — IEEE MA-L (the IEEE MA-L registry + REST API)

MA-M / MA-S blocks

none found under this org name [Confirmed] — the IEEE MA-S registry (local cache)

Related-but-distinct registration

00:07:C3 is registered to plain org name "Thomson" (likely Thomson S.A., France) — not this Belgian entity, deliberately excluded from this entry's prefix set [Confirmed] — https://services13.ieee.org/RST/standards-ra-web/rest/assignments/?registry=MA-L&text=Thomson+Telecom+Belgium

Company lineage / status

Thomson Telecom Belgium was the Belgian CPE division of Thomson SA; Thomson SA rebranded to Technicolor in 2010 and the unit's products continued as "Technicolor Delivery Technologies Belgium" / Technicolor Connected Home, later spun off and rebranded Vantiva (2023–2024) — so this legal entity name is likely no longer active on its own [Likely] — https://maclookup.app/vendors/thomson-telecom-belgium, https://usermanual.wiki/Technicolor-Delivery-Technologies-Belgium/TG789VN/html

Device types

ADSL/VDSL2 residential gateways with integrated VoIP, DOCSIS cable modems [Confirmed] — https://www.provu.co.uk/technicolor-tg585.html, https://usermanual.wiki/Technicolor-Delivery-Technologies-Belgium/TG670/html

Notable products

Speedtouch and Technicolor TG-series gateways (TG585, TG588v, TG670, TG784, TG789vn, TG789vac), DOCSIS modems (DCM476, TC7200) [Confirmed] — https://www.provu.co.uk/technicolor-tg588v-v2.html, https://www.amazon.com/Technicolor-DCM476-Digital-updated-firmware/dp/B00FPPFUBE

Security context

CERT/CC VU#913565 (CVE-2023-31808) documents hard-coded service accounts on the Technicolor TG670 permitting full WAN administrative takeover; CERT/CC states the vendor did not respond to coordinated disclosure, patch status unclear. Older TG585/TG588/TC7200-family devices carry separate documented auth-bypass/XSS/info-disclosure issues.

Registration/assignment date

not published by IEEE for any of the 9 blocks; correctly left null rather than sourced from third-party lookup tools [Confirmed absence] — no citation (absence of a field, not a claim)

Assignment-date caveat

maclookup.app displays per-prefix "registration dates" (e.g. 00:90:D0 → 2000-11-09) that are third-party database artifacts from that site's own scrape history, not IEEE-published facts, and are not recorded here as allocated dates [Confirmed] — https://maclookup.app/vendors/thomson-telecom-belgium

Website

no current live official site identified for this specific legal entity (absorbed into Technicolor/Vantiva lineage) [Unknown] — not cited (no source found)

Analyst note

9-block, well-documented, actively-CVE-tracked CPE vendor — substantive registration, not a shell. Treat this OUI on a LAN as legacy/EOL consumer ISP-CPE hardware with an above-average history of remotely exploitable vulnerabilities.
