Quanta Cloud Technology (QCT) has no distinct IEEE registrant of its own — its hardware surfaces under the parent "Quanta Computer Inc." registrant, which holds 20 MA-L blocks (about 335.5 million addresses). Verified Quanta Computer samples include 00:C0:9F, 00:16:36, 00:1B:24, 2C:60:0C, 90:82:C3, and A8:1E:84; related but separate registrants include "Quanta Storage Inc." (3 blocks, MA-L + MA-M) and "Quanta Microsystems, Inc." QCT was established in May 2012 as Quanta Computer's datacenter and cloud arm, with offices in Taoyuan, Taiwan and San Jose, California. These OUIs appear on cloud and hyperscale servers, storage systems, datacenter switches, and rack-scale solutions. The key analyst point is a classic ODM "OUI ≠ retail brand" case compounded by the subsidiary relationship: QCT servers carry Quanta Computer OUIs. For triage, a Quanta Computer OUI in a datacenter fleet may be a QCT hyperscale server, a Quanta-built laptop, or OEM gear Quanta manufactured for another brand — context (rackmount vs. client) disambiguates.

- Special note
- Classic ODM "OUI ≠ retail brand" case compounded by the subsidiary relationship — QCT servers carry Quanta Computer OUIs (Quanta Computer is the laptop ODM, already covered). QCT has been reported to ship roughly one in seven servers worldwide (The Register, 2013-03-12, on 2012 sales) and among top GPU-server shippers. The IEEE registry publishes no assignment dates, so none is stated here. [Confirmed]
