China Dragon Technology — 32 prefixes (MA-L); Shenzhen Wi-Fi module ODM, OUI ≠ device brand

China Dragon Technology holds 32 MA-L blocks registered to "China Dragon Technology Limited", a Shenzhen, Guangdong fabless/ODM maker of Wi-Fi and wireless communication modules. The cached IEEE registry shows two address strings for the same registrant — the older "B4 Bldg. Haoshan 1st Industry Park, Shenzhen Guangdong CN 518104" and a more detailed "B4 Building, No.3 First Industrial Zone, Nanpu Road, Lao Community, Xinqian Street, Baoan District, Shenzhen CN 518100" — both in Bao'an District, Shenzhen, differing only in street detail and postcode, consistent with an address update across registration rounds. Verified sample prefixes include 00:7E:56, 04:39:26, 0C:CD:D0, E0:51:D8, and E0:75:26. The key analyst point is the module pattern: a China Dragon OUI identifies a China Dragon Wi-Fi module, not the brand on the box. The company's primary output is 2.4 GHz and dual-band (2.4/5 GHz) 802.11b/g/n/ac modules — some with Bluetooth 5.0 combo radios — certified under FCC grantee code ROW as Single Modular Approval components for integration into host devices. These modules turn up inside IP surveillance cameras (RTSP/ONVIF PTZ models such as the V360 Pro), smart-home appliances, and other white-label IoT endpoints. For triage, a China Dragon address in DHCP or switch tables most likely means a consumer IoT device whose embedded Wi-Fi module came from China Dragon as an OEM component — a normal supplier scenario, not inherently a rogue-device signal.

IEEE assignment

32 prefixes → "China Dragon Technology Limited", registered Shenzhen, Guangdong, China [Confirmed] — IEEE MA-L (32 MA-L rows confirmed in the cached registry)

Registry / block size

MA-L (24-bit OUI); 32 blocks. No MA-M (the IEEE MA-M registry) or MA-S (the IEEE MA-S registry) assignments exist for this registrant [Confirmed] — IEEE MA-L; cross-checked the IEEE MA-M registry and the IEEE MA-S registry (no hits). Third-party tallies vary slightly (maclookup.app 32, hwaddress.com 34) — the IEEE registry is authoritative.

HQ / country

Shenzhen, Guangdong, China — two registry address variants: "B4 Bldg. Haoshan 1st Industry Park, Shenzhen Guangdong CN 518104" and "B4 Building, No.3 First Industrial Zone, Nanpu Road, Lao Community, Xinqian Street, Bao'an District, Shenzhen CN 518100"

[Confirmed] — IEEE MA-L; address also echoed by hwaddress.com

Company status

active (OEM/ODM wireless-module supplier) [Likely] — FCC grants under grantee code ROW active across multiple recent filings; no official corporate site for the Shenzhen entity positively confirmed

Device types

2.4 GHz and dual-band (2.4/5 GHz) Wi-Fi modules (802.11b/g/n, 802.11ac), Wi-Fi/BT5.0 combo modules; embedded into IP cameras, smart-home appliances, and IoT endpoints [Confirmed] — fccid.io (grantee ROW: e.g. ROW-C4ESP3200, ROW-CDW61822CE, ROW-61821CE)

Notable products

OEM Wi-Fi / Wi-Fi+BT combo modules (Single Modular Approval); end products include IP surveillance cameras (RTSP/ONVIF, V360 Pro PTZ and similar) [Confirmed] — fccid.io; ispyconnect.com / camlytics.com camera databases

Verified prefix sample

00:7E:56, 04:39:26, 0C:CD:D0, E0:51:D8, E0:75:26 (all MA-L) [Confirmed] — IEEE the IEEE MA-L registry; maclookup.app, hwaddress.com

Allocated date

Unknown — IEEE publishes no assignment/registration dates for MA-L OUI blocks, and no date data is present in the cached registry. Per-prefix "registration dates" shown by third-party tools (maclookup.app, hwaddress.com) are database artifacts, not IEEE facts, and are NOT recorded here.

[Confirmed] — IEEE the IEEE MA-L registry columns are Registry, Assignment, Organization Name, Organization Address only

FCC grantee code

ROW (confirmed across multiple filings: ROW-C4ESP3200, ROW-CDW61822CE, ROW-61821CE, ROW-B18188F2C) [Confirmed] — fccid.io

Special note

Module-OUI flag. A China Dragon OUI identifies a China Dragon Wi-Fi/BT module REGARDLESS of device brand (same pattern as AzureWave/Tuya/Espressif). Commonly embedded in white-label IoT and IP cameras. No CVE or threat-actor attribution specific to this vendor was found; generic low-cost-IoT risks (default credentials, weak update cadence) apply.

[Likely] — umatechnology.org; no vendor-specific advisory located

Related vendors

peer Wi-Fi/BT module ODMs (AzureWave, Tuya) — not registrant-linked. Note "China Dragon IT Limited" (Hong Kong, chinadragonhk.com) is a DISTINCT company, not the IEEE registrant. [Likely] — chinadragonhk.com

Analyst note

A China Dragon address most likely indicates a consumer IoT device (smart camera, smart plug, smart appliance) whose embedded Wi-Fi module came from China Dragon as an OEM component; the end-user brand is usually unrelated. Use for module-level fingerprinting, not brand attribution; not inherently rogue.
