Sercomm France Sarl — 4 prefixes (MA-L)

A MAC address beginning with 2C:08:23, 2C:93:FB, 34:17:DD, or 54:EC:B0 belongs to Sercomm France Sarl, the IEEE-registered French entity behind networking gear manufactured by Sercomm Corporation, a Taiwan-headquartered ODM. No single device model has been publicly documented for any of these four specific prefixes, so identification stops at the vendor/manufacturer level rather than a named product.

Sercomm France Sarl holds four separate MA-L (48-bit) OUI assignments in the IEEE registry, all sharing the same Issy-les-Moulineaux, France address — a repeat-registration pattern consistent with an active manufacturer rather than a one-off allocation. No MA-M or MA-S blocks were found under this registrant name.

The registrant is the French arm of Sercomm Corporation, founded in 1992 and headquartered in Taipei. Sercomm designs and manufactures DOCSIS cable modems, PON/fiber ONTs, DSL/FTTH and 4G/5G fixed-wireless-access CPE, Wi-Fi routers and mesh systems, and IoT/security cameras supplied to ISPs and telecom operators worldwide.

Sercomm-built equipment carries a documented security history at the corporate-group level: a hidden TCP/32764 diagnostic backdoor found in Sercomm-made routers OEM'd to Linksys and Netgear (2013-2014, re-introduced after an initial patch), CVE-2021-27702 in an Etisalat-branded router, CVE-2021-44080 in the h500s, and a 2025 advisory covering further vulnerabilities in Sercomm wireless routers. None of these sources ties the flaws to a specific one of these four French-registered prefixes.

Analyst note

multi-OUI French registrant with corporate substance via its Taiwan parent's well-documented ODM product line; treat any single-prefix device claim as unverified until a source names a specific model against one of these four blocks.
