Huawei holds the largest OUI footprint in this batch: about 1,378 blocks (~23.1 billion addresses) under "HUAWEI TECHNOLOGIES CO.,LTD", plus about 630 more under the consumer-focused "Huawei Device Co., Ltd." Registrations span MA-L blocks and CID (Company Identifier) assignments, and addresses cluster around Shenzhen (Bantian, Longgang District) and Dongguan (Songshan Lake). These OUIs appear on smartphones (Mate/P-series), enterprise routers and switches, carrier/telecom base-station gear, and a wide range of consumer devices. Huawei's chip subsidiary HiSilicon designs the Kirin and Ascend SoCs; HiSilicon-attributed OUIs are harder to surface and many Huawei/HiSilicon-powered devices fall under the much larger parent allocation. A piece of context that matters for where these OUIs turn up: Huawei's networking and 5G gear has been banned or phased out of mobile networks by the US, UK, Australia, New Zealand, Japan, and Taiwan, and the UK set an end-of-2027 removal deadline for Huawei equipment in 5G networks — so finding a Huawei networking OUI in a regulated carrier or enterprise environment may warrant policy review. For triage, a Huawei OUI may be a handset, a CPE router, or carrier infrastructure, and the device class can't be assumed from the OUI alone.
- IEEE assignment
- ~1,378 prefixes → HUAWEI TECHNOLOGIES CO.,LTD (Shenzhen); ~630 → Huawei Device Co., Ltd. (Dongguan) [Confirmed] — IEEE MA-L + CID
- Registry / block size
- MA-L plus CID; parent ~1,378 blocks (~23.1B addresses); Huawei Device ~630 blocks [Confirmed assignments] — maclookup.app (IEEE-derived; counts are a current third-party snapshot and drift). NOTE: IEEE's public OUI data publishes NO assignment/registration date (oui.csv columns are only Registry, Assignment, Organization Name, Organization Address); any "date registered" from third-party tools is a database artifact, not an IEEE fact.

- Analyst note
- A Huawei OUI may be a handset, a CPE router, or carrier infrastructure; in regulated enterprise environments an unexpected Huawei networking OUI warrants policy review.
