Ubiquoss Inc — 3 prefixes (MA-L)

A MAC address beginning with 00:07:70, 70:30:5D, or BC:76:F9 belongs to Ubiquoss Inc, a South Korean network-equipment manufacturer, and most plausibly identifies carrier or enterprise network-infrastructure gear such as an Ethernet switch or fiber-access device rather than a consumer product.

Ubiquoss holds three separate IEEE MA-L (/24) blocks — 00:07:70, 70:30:5D, and BC:76:F9 — all registered to the identical company name and South Korea address. Multiple independent OUI grants tied to one identifiable company with a documented product line separate an active vendor from a bare single-block registration.

Founded in 2000 and headquartered in Seongnam-si, Gyeonggi-do, South Korea, Ubiquoss is listed on the KOSDAQ exchange under ticker 264450. The company builds carrier and enterprise network-access equipment — L2/L3 Ethernet switches, GPON/EPON FTTH gear (including the CM-6024A GPON-MDU switch), LTE mobile-backhaul switches, and VDSL2/G.hn DSL products — sold to telecom operators, cable/system operators, and enterprises.

One vendor-specific vulnerability is recorded in the NVD as of an August 2026 search: CVE-2018-10024, a critical (CVSS v3.0 9.8) cleartext-credential exposure in the ubiQuoss Switch VP5208A, disclosed in April 2018. This vendor is unrelated to Ubiquiti Inc., the much larger US company behind UniFi and EdgeRouter — generic vulnerability or name searches for "Ubiquiti" surface unrelated results that should not be attributed to Ubiquoss.

Security context

one vendor-specific CVE recorded in the NVD as of an August 2026 search — CVE-2018-10024 (ubiQuoss Switch VP5208A, cleartext-credential exposure via a world-readable file, CWE-522, CVSS v3.0 9.8), disclosed 2018-04-09 [Confirmed] — nvd.nist.gov, tarlogic.com

CVE search completeness

based on one NVD keyword-search API query plus general web search; a second vulnerability database was not additionally cross-checked [Likely] — nvd.nist.gov (keywordSearch=Ubiquoss)

Analyst note

three independently-registered OUI blocks plus a documented, verifiable carrier/enterprise product line place this vendor above the bare single-OUI-registration threshold; a MAC under these three prefixes indicates carrier or enterprise network-access equipment, not consumer hardware
