MAC address vendor

Shenzhen MiaoMing Intelligent Technology Co.,Ltd — 12 prefixes (MA-L)

Primary prefix
8C:E4:DB
Block
MA-L
Status
Active

Summary

// what this is
Shenzhen MiaoMing Intelligent Technology is registered to MAC prefix 8C:E4:DB and 11 more in the IEEE OUI database. When a device's MAC address begins with 8C:E4:DB, that block was registered by Shenzhen MiaoMing Intelligent Technology — the OUI identifies the maker of the network hardware, which is not always the brand on the device.
// analyst note
Treat this vendor as an OEM WiFi/Bluetooth module maker likely embedded inside a white-label router, IoT, or smart-home product rather than a named consumer product line; security posture (default credentials, known vulnerabilities) is Unknown, not benign-by-default.
[ 01 ] — Context

About this vendor.

Updated  ·  Confidence: Medium

Shenzhen MiaoMing Intelligent Technology Co.,Ltd holds 12 separate IEEE MA-L OUI assignments, split evenly across two registrant addresses on file with IEEE: an earlier Dongguan/Tangxia Town address (six blocks) and a later Shenzhen/Longhua District address (six blocks), both under the same company name — one instance of which carries a registry-side double-space typo in the org string, a verbatim artifact rather than a distinct entity. This is not a bare single-OUI shell: the company also holds an active FCC grantee code (2AXHE) with eight distinct equipment filings spanning October 2020 through March 2026, all for WiFi/Bluetooth wireless communication modules built on third-party silicon (Realtek RTL8821CE/RTL8852BE, AICSemi AIC8800DL). That is real device corroboration behind the registry name, consistent with an EMS/module manufacturer whose two address groups reflect relocation or expansion over time rather than coincidence. Web-search background (self-reported, not independently confirmed) points to a company founded around January 2016. No default-credential or vulnerability reporting was found for this vendor in the sources checked, so its security posture is left Unknown rather than assumed benign.

Org name (registry, exact strings)
"Shenzhen MiaoMing Intelligent Technology Co.,Ltd" (Group A, 6 prefixes) and "Shenzhen MiaoMing Intelligent Technology Co.,Ltd" (double space, Group B, 6 prefixes — verbatim registry artifact, same company) [Confirmed] — the IEEE MA-L registry (local IEEE MA-L cache)
Registry / block class
MA-L for all 12 assigned blocks; no MA-M or MA-S entries found for this org [Confirmed] — the IEEE MA-L registry, the IEEE MA-M registry, the IEEE MA-S registry
Assigned prefixes — Group A (Longhua District, Shenzhen address
3F, Building 2, No. 1310, Kukeng Sightseeing Road, Kukeng Community, Guanlan Street, Longhua District, Shenzhen, Guangdong CN 518110): 8C:E4:DB, 74:83:A0, 50:61:7E, 38:7B:01, E8:95:05, 00:84:97 [Confirmed] — the IEEE MA-L registry, cross-referenced against the Wireshark manufacturer database
Assigned prefixes — Group B (Dongguan address
Chudong Science and Technology Park, 111 Shaxin Road, Tangxia Town, Dongguan City, Guangdong CN 523710): B8:99:AE, 40:8C:4C, 50:A1:32, 8C:EA:12, 2C:B0:FD, 38:CA:73 [Confirmed] — the IEEE MA-L registry, cross-referenced against the Wireshark manufacturer database
Company substance
not a bare single-OUI shell — 12 MA-L blocks plus an active FCC grantee code (2AXHE, 8 filings, Oct 2020–Mar 2026), all WiFi/Bluetooth wireless modules on Realtek RTL8821CE/RTL8852BE and AICSemi AIC8800DL chipsets [Confirmed] — fccid.io/2AXHE, fcc.report FCC-ID 2AXHE-WD8822CS filing
Device / usage context
OEM/EMS-style WiFi+Bluetooth communication modules (e.g. WD8822CS, WD-RTL8821CE, RTL8852BEM2) meant for embedding in other vendors' routers, IoT, and smart-home products — not a consumer end-device brand; no known-vulnerability or default-credential reporting found
[Likely] — fccid.io/2AXHE, fcc.report FCC-ID 2AXHE-WD8822CS
Company founding / identity
self-reported founding circa January 2016, HQ at the Longhua District Shenzhen address, described as an EMS provider making WiFi 2.4G+5.8G+11AC+BT modules — sourced from secondary aggregator (PatSnap), NOT independently confirmed via the company's own site (weidcn.com failed TLS certificate validation, cert presented was for a different domain)
[Likely] — discovery.patsnap.com/company/shenzhen-miaoming-intelligent-technology
Official website
could not be independently verified; the presumed official domain (weidcn.com) presented a mismatched TLS certificate during the research pass, so no working first-party site is confirmed [Unknown]
Allocated / registration date
no date for any of the 12 prefixes — IEEE's public OUI data (the IEEE MA-L registry) publishes no assignment/registration-date column at all; third-party per-prefix "date registered" values seen on lookup aggregators (e.g. maclookup.app, macaddress.io) are database first-seen artifacts, not IEEE facts, and are not recorded here
[Confirmed as absent] — the IEEE MA-L registry; maclookup.app (source of the caveat, not of a usable date)
IANA Reference
not applicable — this column applies to the port-numbers registry, not OUI/MA-L assignments [Confirmed]
Related vendors
none identified in the sources checked [Unknown]
