Advantech's MAC footprint spans two IEEE registrants that should be aliased to one brand: "ADVANTECH CO., LTD." (the Taiwan HQ entity; 2 blocks, about 33.6 million addresses) and "Advantech Technology (CHINA) Co., Ltd." (the China manufacturing arm; 3 blocks, about 50.3 million addresses). Verified samples include 00:D0:C9 and 74:FE:48 (Taiwan entity) plus 00:0B:AB and C4:00:AD (China entity). The Taiwan record lists an address in Taipei, Taiwan, while the China entity is registered at No.666 Han-Pu Rd., Yu-Shan, Kun-Shan, Jiangsu, China. These OUIs appear on industrial PCs (IPCs), embedded single-board computers, IoT gateways (the UNO and WISE series), panel PCs and HMI, industrial automation and I/O, and network appliances. Advantech is one of the world's largest industrial-computing vendors and a peer to Kontron and ADLINK. The key analyst point is that an Advantech OUI maps to the Advantech brand but may resolve to either the Taiwan or China registrant — both should be normalized to "Advantech." For triage, an Advantech OUI in ARP/DHCP almost always identifies Advantech-branded industrial or embedded hardware — IPCs, gateways, panel PCs — typically on OT/factory-floor or edge segments.

- Registry / block size
- MA-L; ~2 blocks (~33.6M) Taiwan + ~3 blocks (~50.3M) China [Confirmed] — maclookup.app (IEEE-sourced)
- HQ / country
- Taiwan entity — Taipei, Taiwan; China entity — No.666 Han-Pu Rd., Yu-Shan, Kun-Shan, Jiangsu 215316, China [Confirmed] — maclookup.app
- Company status
- active; one of the world's largest industrial-computing vendors [Confirmed] — advantech.com
- Device types

- Notable products
- UNO/WISE IoT gateways, industrial PCs, panel PCs/HMI
- Verified prefix sample
- 00:D0:C9, 74:FE:48 (Taiwan); 00:0B:AB, C4:00:AD (China) [Confirmed] — maclookup.app
- Special note
- Two distinct registrants (Taiwan HQ + China manufacturing) — alias both to "Advantech." Peer to Kontron/ADLINK. The IEEE registry publishes no assignment dates, so none is stated here. [Confirmed]
- Related vendors
- Kontron, ADLINK (embedded/industrial-computing peers)
- Analyst note
- An Advantech OUI in ARP/DHCP almost always identifies Advantech-branded industrial/embedded hardware — IPCs, gateways, panel PCs — typically on OT/factory-floor or edge segments; both Taiwan- and China-entity prefixes resolve to Advantech.
