ADVANTECH CO., LTD. — 2 prefixes (MA-L); industrial / embedded computing, OUI = brand

A MAC address beginning with 00:D0:C9 or 74:FE:48 belongs to ADVANTECH CO., LTD., the Taipei-headquartered parent company of the Advantech industrial- and embedded-computing group, and typically appears on industrial PCs (IPCs), embedded single-board computers, IoT gateways (the UNO and WISE series), panel PCs and HMI, industrial automation and I/O modules, and network appliances.

The IEEE registry assigns exactly two MA-L blocks to this legal-entity string — roughly 33.6 million addresses — and no MA-M or MA-S sub-allocations. Both records carry Taipei, Taiwan addresses. Advantech is one of the world's largest industrial-computing vendors and a direct peer to Kontron and ADLINK.

The wider Advantech corporate family holds several other IEEE registrant strings that are RELATED but legally distinct and must not be merged into this entry: Advantech Technology (CHINA) Co., Ltd. (the Kunshan, Jiangsu manufacturing subsidiary, which holds 00:0B:AB, C4:00:AD, CC:82:7F and 28:87:AF), Advantech Czech (C4:B1:6B), Advantech AMT Inc. of Canada (00:0E:02), and the similarly-named but unrelated Korean entity ADVANTECH TECHNOLOGIES CO.,LTD (00:14:53). Each is registered separately with IEEE and is covered by its own entry.

For triage, an 00:D0:C9 or 74:FE:48 address in ARP/DHCP almost always identifies Advantech-branded industrial or embedded hardware — IPCs, gateways, panel PCs — typically on OT/factory-floor or edge segments. A sibling Advantech-family prefix indicates the same brand but a different registrant, so resolve the specific prefix rather than assuming this record.

Special note

OUI = BRAND. This entry covers the Taiwan parent registrant ONLY. Advantech Technology (CHINA) Co., Ltd. (00:0B:AB, C4:00:AD, CC:82:7F, 28:87:AF) is a related but distinct IEEE registrant with its own entry — do not fold its prefixes into this record. Peer to Kontron/ADLINK. [Confirmed]

Analyst note

An 00:D0:C9 or 74:FE:48 address in ARP/DHCP almost always identifies Advantech-branded industrial/embedded hardware — IPCs, gateways, panel PCs — typically on OT/factory-floor or edge segments. Sibling Advantech-family prefixes resolve to the same brand but to different registrants, and a MAC prefix is trivially spoofable, so don't rely on it for access control.
