DataFab Systems Inc. — 2 prefixes (MA-L)

A MAC address starting with 00:30:FF or 00:25:D9 belongs to DataFab Systems Inc., a Taiwan-based manufacturer best known for flash-memory card readers, writers, and interface adapters. Both prefixes are dedicated MA-L (24-bit OUI) assignments registered solely to this organization — neither is a shared IEEE Registration Authority base block, so either range legitimately points to DataFab-made hardware rather than a pool of unrelated vendors.

DataFab Systems is a real, identifiable company rather than a bare registration. A Taiwan business-directory profile describes it as founded in 1992 and OTC-listed on Taiwan's TAISDAQ market under stock code 6199 since November 2002, with ISO 9001:2000 and ISO 14001:2004 certifications reported. Its product line is corroborated independently: archived manuals and driver pages document CompactFlash, PCMCIA, USB 2.0, ExpressCard, and FireWire card readers/adapters, and a DataFab reader was reviewed alongside a PQI product in early-2000s hardware press.

The two OUI assignments carry different registered addresses — Room #1910, 19F, No. 333, Taiwan, TW R.O.C. for 00:30:FF, and 385-3 Hongzun Road, Pingzhen City, Taoyuan County, TW 32466 for 00:25:D9 — consistent with a later re-registration rather than two unrelated firms sharing a name. No live corporate website was found in this pass, so current operating status (active vs. dormant/dissolved) is Unknown.

IEEE's public IEEE MA-L registry exposes no assignment or registration date; any "registered on" date shown by third-party lookup tools for these prefixes is a database artifact, not an IEEE fact, and is not reproduced here. No CVE or NVD record was found for DataFab or DataFab Systems as of an August 2026 search, and no malware/trojan association surfaced in general web search — treated as an unconfirmed negative, not a confirmed-clean verdict, given the age of the hardware.

Verified sample prefixes (both MA-L, DataFab Systems Inc.)

00:30:FF, 00:25:D9 [Confirmed] — the IEEE MA-L registry 0030FF, the IEEE MA-L registry 0025D9

Date caveat

IEEE's MA-L registry publishes no assignment/registration date; third-party "registered on" dates for these prefixes are database artifacts, not IEEE facts [Confirmed] — the IEEE MA-L registry 0030FF, the IEEE MA-L registry 0025D9

Special note

Both prefixes are dedicated, non-pooled assignments to a single named organization — a MAC in either range indicates DataFab-manufactured hardware, unlike shared IEEE-RA base blocks (e.g. 70:B3:D5) that must never be attributed to one vendor

[Confirmed] — the IEEE MA-L registry 0030FF, the IEEE MA-L registry 0025D9

Related vendors

None identified [Unknown]

Analyst note

A MAC in the 00:30:FF or 00:25:D9 range identifies DataFab Systems-manufactured storage-peripheral hardware; the company's current operating status could not be confirmed, so treat as legacy/likely-discontinued consumer hardware rather than an actively supported product line
