ML vision Co.,LTD holds a single MA-L block, 9C:DE:4D, registered to a unit at Bucheon Techno Park in Gyeonggi-do, South Korea. The MA-L assignment is a 24-bit OUI carrying roughly 16.77 million addresses, confirmed in the IEEE oui.csv registry and absent from the MA-M (mam.csv) and MA-S (oui36.csv) files — so this is a full OUI block, not a fragment of a shared one. Beyond the registry line itself, the company keeps a low public profile: no vendor website, product catalog, company-registry filing, or funding announcement surfaced after an English- and Korean-language research pass. The name "ML Vision" and the Bucheon Techno Park address — a dense electronics-manufacturing cluster — are consistent with a machine-vision or smart-camera hardware maker, and a neighboring tenant in the same building (403-dong), Uhtek Co., Ltd., is a documented CCTV-camera exporter. That neighbor is contextual corroboration only: no direct link between ML Vision and Uhtek is confirmed, so device type stays Unknown pending vendor confirmation or physical inspection. A 9C:DE:4D address on a network is almost certainly genuine ML Vision hardware — the block is singly assigned with no evidence of sharing or spoofing — but the IEEE publishes no registration date for any OUI, so the 2022-08-03 date shown on third-party lookup tools is a database artifact and must never be presented as an IEEE fact.
- IEEE assignment
- 9C:DE:4D → ML vision Co.,LTD, MA-L block (24-bit OUI, ~16.77M addresses) [Confirmed] — IEEE oui.csv (enrichment/registries/oui.csv, line 441); maclookup.app/vendors/ml-vision-co-ltd
- Registry / block size
- MA-L; single assignment; present in oui.csv only, NOT in mam.csv (MA-M) or oui36.csv (MA-S) [Confirmed] — IEEE oui.csv. NOTE: IEEE's public OUI data publishes NO assignment/registration date; the 2022-08-03 value on maclookup.app is a third-party database artifact, not an IEEE fact, and must not be displayed as a registration date.
- Registered address
- #503, 403-dong, Bucheon Techno Park, 655, Pyeongcheon-ro, Bucheon-si, Gyeonggi-do, KR 14502 [Confirmed] — IEEE oui.csv
- Country
- South Korea (KR) [Confirmed] — IEEE oui.csv
- Allocated date
- Unknown — IEEE publishes none for OUIs; no first-party date available [Unknown] — IEEE oui.csv (no date column)
- Company status
- Unknown — no company-registry entry, active website, or funding announcement found; IEEE assignment confirms existence as of registration, and no evidence of dissolution found [Unknown] — research pass 2026-06-19 (no source)
- Device types
- Unknown — no products or device types confirmed in any public source. Name "ML Vision" implies machine-learning / computer-vision hardware (e.g. smart cameras, embedded AI vision devices); the Bucheon Techno Park address is shared with Uhtek Co., Ltd., a documented CCTV-camera exporter, weakly corroborating a camera/vision cluster, but no direct ML Vision–Uhtek association is confirmed [Unknown] — importgenius.com/suppliers/uhtek-co-ltd (neighbor only)
- Vendor website
- Unknown — no public website found after Korean and English search [Unknown] — research pass 2026-06-19 (no source)
- Industry
- Likely electronics / embedded hardware (vision or camera technology), inferred from company name and Gyeonggi-do Bucheon Techno Park location; not confirmed from public sources [Likely] — inference from IEEE registry address
- Security context
- No CVEs, public security incidents, or threat-intel references found for ML vision Co.,LTD or OUI 9C:DE:4D [Unknown] — research pass 2026-06-19 (no source). If device type is later confirmed as networked camera / embedded AI vision hardware, standard IP-camera hygiene applies (credential hardening, firmware updates, network segmentation) — a general class note, not a vendor-specific finding.
- Analyst note
- Low-public-profile Korean hardware company holding one MA-L OUI block. A 9C:DE:4D address is almost certainly genuine ML Vision hardware (no evidence of shared block or spoofing). Treat device type as Unknown. Do NOT display the maclookup.app 2022-08-03 date as an IEEE registration date. [Likely] — maclookup.app/vendors/ml-vision-co-ltd; IEEE oui.csv
