Inteno Broadband Technology AB — 4 MA-L prefixes

A MAC address beginning with 00:22:07, 20:1F:31, 44:D4:37, or 60:03:A6 belongs to Inteno Broadband Technology AB, a Swedish manufacturer of residential and operator-grade broadband customer-premises equipment. Devices carrying these prefixes are typically fiber ONTs/IADs, DSL or fiber residential gateways, and VoIP-enabled WLAN routers rather than general consumer electronics or IT infrastructure gear.

Inteno holds four separate IEEE MA-L assignments, all registered to the same Skärholmen, Sweden address — a signal of real manufacturing volume rather than a single opportunistic registration. The company shipped named hardware lines (FG101, DG200/DG201/DG400, EG200/EG400-R1/EG500) documented in independent product manuals, distinguishing it from shell registrants with no traceable product.

Corporate history places Inteno Group, backed by Accent Equity, acquiring Seliro and its subsidiary Tilgin, before merging with (or being acquired by) Genexis Group AB to form a combined European connected-home CPE supplier spanning the Inteno, Tilgin, iopsys, Seliro, and Genexis brands. Current DNS/TLS certificate chains for genexis.se, genexis.eu, iopsys.eu, tilgin.com, and fiberxport.eu independently corroborate this shared group structure.

Multiple independently-sourced CVEs affect named Inteno models: CVE-2019-13140 (EG200 JUCI ACL misconfiguration exposing a 3DES key), a 2016 CWMP/TR-069 certificate-validation flaw on EG500/FG101/DG201 enabling MITM firmware replacement, and a DG400 denial-of-service via crafted random-MAC packets. These findings are consistent with the general severity profile of consumer/operator CPE routers, not exotic IoT-botnet-grade abuse.

IEEE assignment

4 MA-L prefixes → Inteno Broadband Technology AB, registered Skärholmen, SE 127 39, Sweden [Confirmed] — IEEE MA-L

Registry / block size

MA-L (24-bit OUI); 4 IEEE prefixes [Confirmed] — IEEE OUI registry. NOTE: IEEE's public OUI data publishes NO assignment/registration date (the IEEE MA-L registry columns are only Registry, Assignment, Organization Name, Organization Address); any "date registered" on third-party tools is a database artifact, not an IEEE fact.

Analyst note

A substantive multi-OUI manufacturer with traceable corporate history and independently-documented CVEs, not a bare shell registration — appropriate to finalize as a consolidated vendor entry rather than leave as a 410.
