MAC address vendor

Hongkong Nano IC Technologies Co., Ltd — 2 prefixes (MA-L)

Primary prefix
54:03:84
Block
MA-L

Summary

// what this is
Hongkong Nano IC Technologies is registered to MAC prefix 54:03:84 and 1 more in the IEEE OUI database. When a device's MAC address begins with 54:03:84, that block was registered by Hongkong Nano IC Technologies — the OUI identifies the maker of the network hardware, which is not always the brand on the device.
// analyst note
Multiple OUI assignments plus a verifiable (if thin) corporate registration distinguish this from a bare single-block shell; treat device/product claims as Unknown absent further corroboration.

About this vendor.

Updated  ·  Confidence: Medium

Hongkong Nano IC Technologies Co., Ltd holds two IEEE MA-L blocks, 54:03:84 and 28:31:7E, both registered to the same organization name and the same Wan Chai, Hong Kong address, which rules out a coincidental name collision between the two allocations. A Hong Kong company-registry aggregator separately shows a company of a closely matching name (CR No. 2107951) incorporated 2014-06-12 and still marked "Live" as of its most recent annual return, though that registry entry lists a different registered address (Causeway Bay rather than Wan Chai) and gives no business-activity classification or director information — so the corporate substance behind the two OUI blocks is confirmed to exist but is thin. No official company website, product line, chipset, or device teardown referencing either prefix turned up in general or IoT/camera-forum-targeted search, so this entry should not be read as describing an identifiable consumer product line — only a real, multi-block IEEE registrant with a verifiable but sparse corporate footprint. A distinct, unrelated vendor with a similar name, "HangZhou Nano IC Technologies Co., Ltd" (DC:22:6F, mainland China), must not be merged into this slug.

IEEE assignment
54:03:84 and 28:31:7E → "Hongkong Nano IC Technologies Co., Ltd" [Confirmed] — the IEEE MA-L registry
Registry / block size
MA-L (24-bit OUI) for both blocks [Confirmed] — the IEEE MA-L registry
Registered address
Rm. 19C, Lockhart Centre, 301-307 Lockhart Rd., Wan Chai, Hong Kong, CN 999077 (identical on both blocks, minor punctuation variance between rows) [Confirmed] — the IEEE MA-L registry
No MA-M / MA-S blocks found under this org name [Confirmed] — the IEEE MA-M registry, the IEEE MA-S registry
Company registry status
"Hongkong Nano IC Technologies Co., Limited," CR No. 2107951, incorporated 2014-06-12, private company limited by shares, status "Live," most recent annual return 2025-06-12; registered address given as Lee Garden One, 33 Hysan Avenue, Causeway Bay — differs from the OUI-registration address and is unexplained [Likely] — https://www.ltddir.com/companies/hongkong-nano-ic-technologies-co-limited/ (third-party aggregator, not the official HK e-Registry)
Device types / notable products
Unknown — no official website, product page, datasheet, or device/forum reference to either prefix found [Unknown]
Allocation date
Unknown — IEEE the IEEE MA-L registry has no date column and publishes no assignment date. Third-party aggregators (maclookup.app, uic.io) show scrape/crawl dates (~2016-10 for 54:03:84, ~2020-01 for 28:31:7E) that are database artifacts, not IEEE facts, and are not recorded as registration dates here
[Confirmed] — the IEEE MA-L registry; https://maclookup.app/vendors/hongkong-nano-ic-technologies-co-ltd
Related-but-distinct vendor
"HangZhou Nano IC Technologies Co., Ltd" (DC:22:6F, mainland China) shares a similar name but is a separate legal entity in a different city — do not merge into this slug [Confirmed] — the IEEE MA-L registry, the Wireshark manufacturer database cross-reference
Analyst note
two independently-assigned MA-L blocks plus a real (if thin) Hong Kong corporate registration is enough to distinguish this from a bare single-block shell, but the total absence of product, device, or website corroboration means claims about what hardware ships under this vendor name should stay Unknown.
