MAC address vendor

IRay Technology — two distinct Chinese registrants sharing a near-identical name (3 MA-L prefixes)

Primary prefix
64:5E:2C
Block
MA-L
Status
Active

Summary

// what this is
IRay Technology is registered to MAC prefix 64:5E:2C and 2 more in the IEEE OUI database. When a device's MAC address begins with 64:5E:2C, that block was registered by IRay Technology — the OUI identifies the maker of the network hardware, which is not always the brand on the device.
// analyst note
Do not treat 'iray'/'IRay' as a single vendor for classification purposes — confirm which of the two entities a given prefix belongs to before attributing device type or company identity.

About this vendor.

Updated  ·  Confidence: Medium

"IRay Technology" is not one company in the IEEE registry — it is two. The cached MA-L data holds three matching blocks: 64:5E:2C and 90:74:9D, both registered to "IRay Technology Co., Ltd." at an identical Yantai, Shandong address, and a third, E0:79:C4, registered to "iRay Technology Company Limited" at a different address in Pudong, Shanghai. The Yantai pair maps to the InfiRay brand, a thermal-imaging and infrared-optics manufacturer founded 2009 that has since opened a US subsidiary and drawn US State Department sanctions coverage in 2024 over alleged dual-use exports to Russia — enough independent corroboration (a public brand identity, a US HQ, market-share reporting, sanctions press) to clear the bar for a real, documented vendor rather than a bare registration. The Shanghai registrant is a separate company making X-ray flat-panel detectors and digital-radiography components for medical and industrial imaging, with its own corporate site and trade-directory listings, but only one OUI block and single-source web corroboration. Because the two entities differ in legal name, address, and product line, this entry documents both explicitly rather than silently merging them, and downstream lookups should route by prefix rather than by the shared "iray" string.

IEEE assignment (Yantai)
64:5E:2C, 90:74:9D → "IRay Technology Co., Ltd." — 11th Guiyang St., Yantai, Shandong, CN 264000 [Confirmed] — the IEEE MA-L registry
IEEE assignment (Shanghai)
E0:79:C4 → "iRay Technology Company Limited" — Building 45, No. 1000, Jinhai RD., Pudong New Area, Shanghai, CN 201206 [Confirmed] — the IEEE MA-L registry
Registry / block size
MA-L (24-bit OUI) for all three prefixes; no matching MA-M or MA-S records for either entity [Confirmed] — the IEEE MA-L registry, the IEEE MA-M registry, the IEEE MA-S registry
Company identity (Yantai)
trades as InfiRay, founded 2009, thermal-imaging/infrared optics manufacturer (thermal cameras, infrared detectors, night-vision modules), opened a Texas branch (2020) and a US HQ (Dec 2023) [Likely, single web angle] — https://en.wikipedia.org/wiki/InfiRay, http://en.iraytek.com/
Security/geopolitical note (Yantai)
US State Department sanctioned Yantai IRay Technology Co., Ltd. on 1 May 2024 over alleged supply of dual-use thermal-scope/aerospace-relevant tech to entities in Russia; company is a subsidiary of Shanghai-listed Raytron

Company identity (Shanghai)
iRay Technology Company Limited, founded 2011, headquartered in Pudong (production in Zhangjiang and Taicang), makes X-ray flat-panel detectors and DR imaging solutions for medical/dental/veterinary/security/industrial use [Likely, single web angle] — https://www.iraygroup.com/site/company?lang=EN
Device types
Yantai → thermal-imaging cameras, infrared detectors, night-vision modules; Shanghai → X-ray flat-panel detectors, digital-radiography imaging components [Likely] — vendor sites above
Org status
both entities appear active (current corporate sites, current trade-directory listings) [Likely] — http://en.iraytek.com/, https://www.iraygroup.com/
Date fields
IEEE's the IEEE MA-L registry publishes no assignment/registration date for any of the three prefixes; none recorded [Confirmed] — the IEEE MA-L registry
Existing pipeline state
no prior /mac/vendor/iray-technology/, .CHECK.md, or this site's own enrichment records row existed before this cycle [Confirmed] — this site's own enrichment records, this site's own enrichment records
Disambiguation
the two registrants are almost certainly unrelated despite the shared "iray" name — different legal-entity strings ("Co., Ltd." vs "Company Limited"), different addresses/cities, and different product lines (thermal imaging vs X-ray) [Likely] — the IEEE MA-L registry, vendor sites above
Related vendors
none confirmed; Yantai entity is a subsidiary of Raytron (Shanghai Stock Exchange-listed parent) per sanctions coverage [Likely] — https://www.outdoorlife.com/gear/iray-parent-company-sanctions/
