Portwell — 1 prefix (MA-L); industrial / embedded computing, OUI = brand
Summary
- // what this is
- Portwell is registered to MAC prefix
00:90:FBin the IEEE OUI database. When a device's MAC address begins with00:90:FB, that block was registered by Portwell — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- A 00:90:FB device is almost certainly Portwell industrial/embedded hardware — an industrial PC, network appliance, or COM-module-based system, not a consumer device.
About this vendor.
Portwell holds a single MA-L block — 00:90:FB (about 16.8 million addresses) — registered as "PORTWELL, INC." at 7F-4, No. 160, Sec. 6, Taipei, Taiwan; the company's U.S. arm, American Portwell Technology, operates from Fremont, California, but no separate "American Portwell" IEEE registrant surfaced, so this Taiwan HQ block covers the brand. These OUIs appear on industrial PCs, embedded single-board computers, COM modules, network-security appliances, and edge-computing platforms. Portwell is a peer to Advantech, Kontron, ADLINK, Axiomtek, IEI, and AAEON. The key analyst point is that a Portwell OUI maps cleanly to the Portwell brand. For triage, a 00:90:FB device is almost certainly Portwell industrial or embedded hardware — an industrial PC, network appliance, or COM-module-based system — not a consumer device.
