MAC address vendor

Genexis — 7 prefixes (MA-L); European fiber CPE, OUI = brand / ISP-supplied

Primary prefix
00:0F:5D
Block
MA-L
Status
Active

Summary

// what this is
Genexis is registered to MAC prefix 00:0F:5D and 6 more in the IEEE OUI database. When a device's MAC address begins with 00:0F:5D, that block was registered by Genexis — the OUI identifies the maker of the network hardware, which is not always the brand on the device.
// analyst note
A Genexis OUI in a European residential/SMB context indicates an FTTH gateway or ONT — classify as carrier-supplied fiber CPE.

About this vendor.

Updated  ·  Confidence: High

Genexis holds 7 MA-L blocks (about 117.4 million addresses) registered in the Netherlands across three registrant name variants: "Genexis B.V." (34:E3:80, 94:3F:0C, 34:D5:09, 58:00:32) and "Genexis BV" (00:0F:5D, 00:0F:94), both at Lodewijkstraat 1A, Eindhoven, plus "Genexis International B.V." (BC:62:D2) at Maria Hoop — a sibling entity in the same corporate family, consolidated here. These OUIs appear on FTTH and fiber gateways, GPON/XGS-PON ONTs, residential gateways, and Wi-Fi, supplied to European ISPs. Genexis is a European fiber-CPE specialist, and its gear is both brand-mapped and commonly ISP-supplied — Genexis fiber CPE is common in European FTTH deployments, often carrier-branded. For triage, a Genexis OUI in a European residential or SMB context indicates an FTTH gateway or ONT — classify it as carrier-supplied fiber CPE.

IEEE assignment
7 prefixes → "Genexis B.V." (34:E3:80, 94:3F:0C, 34:D5:09, 58:00:32) + "Genexis BV" (00:0F:5D, 00:0F:94) + "Genexis International B.V." (BC:62:D2), Netherlands [Confirmed] — IEEE the IEEE MA-L registry
Registry / block size
MA-L; 7 blocks (~117.4M addresses) [Confirmed] — IEEE the IEEE MA-L registry
HQ / country
Lodewijkstraat 1A, Eindhoven, NL 5652AC (6 of 7 blocks; two legacy rows spell it "Lodewijktraat"); Waldfeuchterbaan 124, Maria Hoop, NL 6105 BP (Genexis International B.V., BC:62:D2 only) [Confirmed] — IEEE the IEEE MA-L registry
Registrant-variant note
"Genexis B.V." and "Genexis BV" are the same registrant at the same Eindhoven street address (punctuation variant). "Genexis International B.V." is a separately-named sibling entity at a second NL address, consolidated here as one vendor lineage — the distinction is disclosed rather than flattened. Two legacy rows carry a country-code typo ("SE" for NL); registry noise, not a different country.
