SFR — 12 prefixes (MA-L)

SFR holds 12 separate IEEE MA-L (24-bit OUI) assignments, all registered to "SFR" with no MA-M or MA-S allocations found in the companion registries. SFR is a major French telecommunications operator — a subsidiary of Altice France with roughly 26 million mobile subscribers — currently the subject of a 2026 acquisition agreement (reported at ~€20.35B) under which Bouygues, Iliad/Free, and Orange would divide its assets, per Bouygues' own investor materials and independent telecom-press coverage. Most of the 12 prefixes trace to SFR's Boulogne-Billancourt or La Plaine Saint-Denis facilities, with one outlier registered at a Nanterre address, and the registry data itself carries visible inconsistencies (spelling, punctuation, and postal-code variants) across otherwise-identical addresses — a source artifact, not a normalization choice. The prefixes correspond to SFR's residential "SFR Box" gateway hardware line, and the firmware has documented reflected-XSS history, though exact CVE identifiers could not be independently confirmed from a blocked source.

IEEE assignment

12 MA-L prefixes registered to "SFR" — 8C:94:CC, CC:2D:1B, 60:35:C0, 6C:61:F4, E4:5D:51, 00:17:33, 00:25:15, E0:A1:D7, 00:1D:16, 30:7E:CB, 44:CE:7D, 24:95:04 [Confirmed] — the IEEE MA-L registry

Registry / block size

MA-L only; zero matches in the IEEE MA-M registry (MA-M) and zero matches in the IEEE MA-S registry (MA-S) [Confirmed] — the IEEE MA-L registry, the IEEE MA-M registry, the IEEE MA-S registry

Registered addresses

11 of 12 prefixes cluster around either "12 rue Jean-Philippe Rameau CS 80001, La Plaine Saint Denis, FR 93634" or "Quai du Point du Jour, Boulogne-Billancourt, FR" (rendered 3 slightly different ways in the source registry — spelling, punctuation, postal code); one prefix (44:CE:7D) is at "5 Rue Noel Pons, Nanterre, FR 92000"

Security context

multiple reflected-XSS issues documented against "SFR Box Router" firmware (branch NB6-MAIN-R3.3.4) across three independent vulnerability trackers; specific CVE IDs and disclosure dates Unknown — the primary tracker (cvedetails.com) returned HTTP 403 on fetch [Likely] — https://www.cvedetails.com/vulnerability-list/vendor_id-13165/SFR.html, https://vulners.com/search/vendors/sfr/products/sfr%20box%20router%20firmware?score=4, https://vulmon.com/searchpage?q=sfr

Date-registered caveat

IEEE's public the IEEE MA-L registry publishes no assignment/registration date column for any of these 12 prefixes; per-prefix "date registered" values shown by third-party tools (e.g. maclookup.app) are database/crawl artifacts, not IEEE facts, and are not recorded as registration dates here
