PT Han Sung Electoronics Indonesia — 4 prefixes (MA-L)

A MAC address beginning with B0:4B:BF, 30:3F:5D, 78:00:A8, or DC:F3:4C belongs to PT Han Sung Electoronics Indonesia, an Indonesian contract manufacturer registered in the Batik Lippo industrial zone near Cikarang, West Java. Trade-data records place the company in the remote-control and consumer-electronics-accessory supply chain, though the exact end product carrying these addresses is not independently confirmed.

The IEEE OUI registry lists the organization name as "PT HAN SUNG ELECTORONICS INDONESIA" — the apparent misspelling of "Electronics" as "Electoronics" is the genuine IEEE-registered spelling, not a repository transcription error. Two independent third-party OUI mirrors (udger.com, maclookup.app) reproduce the identical spelling and registered address, corroborating it. The registered address is JL. Palem 1 Blok DS-6, Kawasan Industri Batik Lippo Cikarang, Desa Cibatu, Kecamatan Cikarang Selatan, Bekasi, Jawa Barat 17550, Indonesia.

This entry clears the vendor-substance bar on two independent grounds: the same registrant holds four separate IEEE MA-L blocks under one name and address (not a bare single-OUI shell), and trade-data aggregators (Matchory, Volza, ImportGenius) independently identify it as an active supplier, listing STARION U.S.A. — a known remote-control OEM — as a top verified customer, with LG Electronics entities appearing among trading partners. This supports, but does not prove, that the OUIs serve wireless remote-control or similar accessory hardware.

No CVEs, security advisories, botnet activity, or default-credential reports were found tied to this vendor or its four prefixes. IEEE's public OUI data publishes no registration date for any assignment; a third-party aggregator shows "registered on 14 July 2016" for B0:4B:BF, but that is a database-scrape artifact, not an IEEE fact, and is not recorded here as one.

Analyst note

Four OUI blocks under one registrant plus independent trade-data corroboration clears the single-OUI-shell bar; end-device mapping (remote-control accessories) is a plausible inference from customer data, not a confirmed fact.
