Shenzhen KTC Technology — 4 prefixes (3 MA-L + 1 MA-M)

The slug vendor-shenzhen-ktc consolidates several IEEE allocations held by Shenzhen KTC Technology, a publicly-listed (Shenzhen Stock Exchange: 001308) Chinese flat-panel display manufacturer founded in 1995 in Longgang District, Shenzhen. The registry shows the company under slightly varying legal names — "SHENZHEN KTC TECHNOLOGY CO.,LTD", "SHENZHEN KTC TECHNOLOGY GROUP", and "SHEN ZHEN KTC TECHNOLOGY.,LTD." — but all point to the same physical address corridor along Wuhe Road/Street in the Bantian/Buji area, so a single vendor entry is more useful than separate near-duplicate per-prefix pages. Three MA-L blocks (E4:65:64, F4:ED:5F, C8:61:D0) and one MA-M block (B0:C5:CA:7xx) belong to this vendor. KTC's product line is display hardware: passive consumer and gaming monitors under the KTC brand (no network connectivity) and Android-based smart interactive flat panels (IFPs) under the wholly-owned Horion subsidiary (LAN, 2.4/5 GHz Wi-Fi, Android 13, remote management). The practical consequence for network work: a KTC/Horion MAC on a managed network most plausibly identifies a Horion IFP in an education or enterprise install — an Android IoT-class device with a meaningful attack surface — rather than a passive gaming monitor. A common data-quality trap to avoid: the Swedish "KTC AB" entry (MA-L 00:23:4C) is a completely different entity and does NOT belong to this vendor.

IEEE assignment

4 prefixes → Shenzhen KTC Technology (CO.,LTD / GROUP legal-name variants), registered Shenzhen, Guangdong, CN [Confirmed] — IEEE MA-L / MA-M (enrichment/registries/oui.csv, mam.csv)

Registry / block size

MA-L (24-bit OUI) for E4:65:64, F4:ED:5F, C8:61:D0; MA-M (28-bit) for B0:C5:CA:7xx [Confirmed] — IEEE registry files. NOTE: IEEE publishes NO assignment/registration date for MA-L/MA-M/MA-S prefixes (registry columns are only Registry, Assignment, Organization Name, Organization Address); any "date registered" on third-party tools is a database artifact, not an IEEE fact.

HQ / country

Wuhe Road/Street area, Bantian / Buji, Longgang District, Shenzhen, Guangdong, CN. Postal codes 518100 (CO.,LTD entries) and 518129 (GROUP entries) [Confirmed] — IEEE registry address fields

Company status

active; publicly listed on Shenzhen Stock Exchange 2022-03-18, stock code 001308; founded 1995 [Confirmed] — en.wikipedia.org/wiki/KTC_Technology, ktc.cn/en

Device types

gaming and consumer LCD/Mini-LED monitors (KTC brand, passive/non-networked); Android-based smart interactive flat panels (Horion brand — networked: LAN, 2.4/5 GHz Wi-Fi, Android 13, RS-232, NFC screen mirroring); LCD TVs, commercial/digital signage, medical displays, smart mirrors, tablets, portable screens [Confirmed] — en.wikipedia.org/wiki/KTC_Technology, ktc.cn/en, global.horion.com

Verified sample prefixes

E4:65:64 (MA-L), F4:ED:5F (MA-L), C8:61:D0 (MA-L), B0:C5:CA:7 (MA-M) [Confirmed] — IEEE registry files; E4:65:64 and F4:ED:5F also corroborated by third-party aggregators [Likely] — uic.io, udger.com, hwaddress.com

Brands / subsidiaries

KTC (consumer/gaming monitors); KTCPLAY (gaming brand, ktcplay.com); Horion (wholly-owned subsidiary est. 2015, interactive flat panels, global.horion.com)

Security note

No CVEs or disclosed vulnerabilities found for KTC or Horion products in a targeted search as of June 2026. Security surface is relevant for the networked Horion IFP line (Android 13, Google EDLA-certified, LAN+Wi-Fi, remote power/message management, NFC mirroring, Google Play access) — treat as Android IoT class in segmentation. Consumer/gaming KTC monitors are non-networked and carry negligible network risk. [Confirmed] — global.horion.com, sauditk.com (Horion 75M5A Pro spec)

IANA reference

none — no IANA protocol assignments found for this vendor [Confirmed]

Data trap

Swedish "KTC AB" (MA-L 00:23:4C) is a DIFFERENT entity and is NOT Shenzhen KTC [Confirmed] — IEEE registry

Analyst note

A KTC/Horion OUI on a managed network most plausibly identifies a Horion interactive flat panel (education/enterprise); the U/L caveats of MAC randomization apply on Wi-Fi as with any vendor, so OUI alone is not authoritative for inventory.
