Allradio Co., Ltd — 2 prefixes (MA-L)

A MAC address starting with 00:07:89 or 1C:EC:72 belongs to Allradio Co., Ltd, a South Korean network equipment manufacturer headquartered in Anyang, Gyeonggi-do. Both prefixes are registered to the identical company name and address in the IEEE registry, and independent research confirms a real, decades-old operating company — not a bare single-OUI shell — with a documented product line of exactly the kind of network hardware that consumes MAC address blocks.

Allradio's self-described product lines include Wi-Fi 6/6E access points (referenced on its own site as "GiGA Wi-Fi" home and enterprise APs), FTTH optical line terminals, LTE/5G repeaters and small cells, and 5G private-network terminals branded "Eum 5G." The company reports Korea Telecom (KT) as a long-running equipment customer, plus smaller engagements with LG U+ and SK Telecom — self-reported claims from Allradio's own corporate history page, not independently cross-checked.

The company traces to a 1980 founding as Sungmi Electronics, passing through several renames — Istel Systems, Dongwon Systems, Dongwon T&I, T&I E — before adopting the Allradio name in September 2018. Korean equipment maker HFR Inc. became its largest shareholder in 2016, and Allradio remains part of the HFR affiliate group, per Allradio's own history page.

IEEE's public OUI registry publishes no assignment date for either block; a "registration date" some MAC-lookup aggregators attach to 00:07:89 (e.g. October 2001) is a database timestamp, not an IEEE fact. Active Wi-Fi Alliance membership could not be confirmed — a directory listing for Allradio resolves to a live 404 on the Alliance's site. No CVEs or malware associations naming "Allradio" were found as of an August 2026 search; carrier-branded deployments may reduce vendor-name discoverability.

Analyst note

00:07:89 and 1C:EC:72 are both direct MA-L assignments to Allradio Co., Ltd, not sub-allocations of a shared IEEE base, so either prefix reliably identifies genuine Allradio-manufactured network gear — expect Wi-Fi APs, FTTH ONT/OLT, or LTE/5G repeater hardware, often deployed under Korean carrier branding (e.g. KT) rather than retailed under the Allradio name.
