Infomark Co., Ltd. — 3 prefixes (MA-L)

A MAC address beginning with 00:1E:31, 58:65:E6, or 88:40:67 belongs to Infomark Co., Ltd., a South Korean manufacturer of WiMAX and LTE mobile routers, CPE, M2M communication modules, and GPS-tracking wearable phones for children.

Infomark Co., Ltd. is a KOSDAQ-listed (ticker 175140) smart-communications-equipment maker headquartered in Seongnam, South Korea, incorporated 24 Jan 2002. It reported roughly 37 employees and about KRW 31.3 billion in revenue for fiscal year 2024, and describes itself as exporting to around 30 countries.

The company holds three dedicated MA-L (24-bit) OUI blocks — 00:1E:31, 58:65:E6, and 88:40:67 — filed from three different Korean addresses that track office moves as the company grew. None of the three sits under a shared IEEE Registration Authority base such as 70:B3:D5 or 8C:1F:64; each is a company-owned block in its own right.

Products tied to the registrant name include WiMAX and LTE mobile routers, USB modem dongles, and the JooN1/JooN2 line of kids' wearable phones with an SOS button and GPS tracking. Infomark has claimed a 2009 world-first WiMAX mobile router and an 8.2mm "world's thinnest" router, the IMW-C1000W, released in 2013.

One device tied to this registrant carries a documented vulnerability: the INFOMARK IMW-C920W router, deployed by Bulgaria's Max Telecom, shipped a bundled miniupnpd 1.0 daemon vulnerable to CVE-2013-0229 and CVE-2013-0230, a remote denial-of-service flaw in SSDP M-SEARCH handling. NVD attributes both CVEs to the third-party MiniUPnPd component, not to Infomark's own firmware — Infomark shipped the vulnerable library, it did not author the flaw.

No CVE naming Infomark as vendor is recorded in the NVD as of an August 2026 search, and no malware, botnet, or data-breach association surfaced in an August 2026 web search. IEEE's the IEEE MA-L registry publishes no assignment date for any of the three blocks; per-prefix dates shown on third-party lookup sites are database artifacts, not IEEE facts, and are not recorded here.

Analyst note

A MAC beginning 00:1E:31, 58:65:E6, or 88:40:67 identifies genuine Infomark Co., Ltd. hardware — WiMAX/LTE routers, CPE, M2M modules, or GPS wearable phones. None of the three blocks sits under a shared IEEE-RA base, so each is a full company-owned assignment. The one documented device vulnerability (IMW-C920W, CVE-2013-0229/0230) traces to a bundled third-party UPnP daemon, not Infomark's own firmware code. [Confirmed]
