Cloud Network Technology Singapore Pte. Ltd. — 57 prefixes (MA-L)

Cloud Network Technology Singapore Pte. Ltd. is a Foxconn (Hon Hai Precision Industry) subsidiary that holds 57 MA-L OUI blocks in the IEEE registry — roughly 956 million assignable addresses. Despite the "Singapore" in its legal name, the IEEE registry address is physical China: B22 Building, No. 51 Tongle Road, Shajing Town, Nanning, Guangxi (CN 530007). That split is typical of the entity's role: incorporated in Singapore (UEN 201716332H, as "Foxconn Cloud Network Technology Singapore Pte. Ltd.", registered 12 June 2017) for holding and investment purposes, but operating as an OEM/ODM manufacturer of networking and Wi-Fi hardware out of mainland China. Because it is a component supplier rather than a consumer brand, this OUI does not appear on "Cloud Network Technology"-branded gear; it surfaces inside the network interfaces of finished third-party products — Sony PlayStation 5 consoles, Sony smart TVs, and HP and Samsung laptops are commonly reported. For network operators, a MAC in one of these blocks indicates an embedded Wi-Fi/NIC module from a Foxconn-supplied device; it should be correlated against the expected device inventory rather than read as a vendor name on the network. No CVEs, threat-actor attribution, or security incidents specific to these OUI blocks were found in public sources as of June 2026. One status nuance worth recording: the Singapore entity is listed as "Amalgamated" in the ACRA register (i.e. merged into another Foxconn group entity), yet it continues to appear under its original name in IEEE OUI data and third-party MAC lookups.

IEEE assignment

57 prefixes → CLOUD NETWORK TECHNOLOGY SINGAPORE PTE. LTD. (IEEE CSV stores the name all-uppercase), registry address in Nanning, Guangxi, China [Confirmed] — IEEE MA-L (enrichment/registries/oui.csv)

Registry / block size

MA-L (24-bit OUI, ~16M addresses each); holds 57 IEEE prefixes (~956M addresses total) [Confirmed registry class — IEEE oui.csv; Likely on the 57 count from maclookup.app, a third-party snapshot that drifts] — maclookup.app. NOTE: IEEE's public OUI data publishes NO assignment/registration date (oui.csv columns are only Registry, Assignment, Organization Name, Organization Address); any "date registered" on third-party tools (e.g. the April 2020–May 2026 spread shown by aggregators) is a database artifact, not an IEEE fact.

HQ / country

B22 Building, No. 51 Tongle Road, Shajing Town, Jiangnan District, Nanning, Guangxi Province, China (CN 530007) — this is the IEEE registry address; the legal incorporation is in Singapore [Confirmed] — IEEE MA-L (enrichment/registries/oui.csv)

Parent company

Foxconn / Hon Hai Precision Industry Co., Ltd. The Singapore entity (UEN 201716332H, "Foxconn Cloud Network Technology Singapore Pte. Ltd.", incorporated 12 June 2017) is an operating/holding subsidiary used for OEM networking hardware and investment functions [Confirmed] — sgpbusiness.com, sg.ltddir.com, marketscreener.com

Company status

"Amalgamated" in the Singapore ACRA register (merged/consolidated into another legal entity; ACRA snapshot last updated March 2026). The entity still appears under its original name in IEEE OUI records and third-party MAC lookups. [Confirmed for the ACRA listing; single-source third-party register] — sg.ltddir.com

Device types

embedded Wi-Fi/networking modules and NICs in third-party consumer and commercial electronics — Sony PlayStation 5, Sony smart TVs, HP and Samsung laptops, plus routers and switches. OEM component supplier, so the OUI appears inside finished devices, not on standalone branded gear. [Confirmed the OEM role; specific device attributions are from user-forum and trade-data reports, Likely] — whirlpool.net.au forum, wpgholdings.com, panjiva.com

Vendor website

no independent public-facing product site for this legal entity; it is a Foxconn subsidiary and the parent group site is https://www.foxconn.com [Likely] — foxconn.com, sg.ltddir.com

Registration date

Unknown — IEEE publishes no OUI registration dates; no date data exists in the cached IEEE registries, and third-party "date registered" values are database artifacts [Confirmed there is no IEEE date] — IEEE oui.csv

IANA reference

not applicable — no IANA RFC reference applies to this OUI entry; the column stays blank [Confirmed] — IEEE MA-L

MA-M / MA-S assignments

none — no MA-M (mam.csv) or MA-S (oui36.csv) blocks found for this organization [Confirmed] — enrichment/registries/mam.csv, oui36.csv

Verified sample prefixes (all MA-L)

A8:3B:76, 30:03:C8, D8:80:83, DC:E9:94, 4C:23:38, DC:56:7B, 48:45:E6, F4:4E:B4 [Confirmed] — IEEE MA-L (enrichment/registries/oui.csv)

Security context

no known CVEs, threat-actor attribution, or public security incidents specific to these OUI blocks (as of June 2026). Devices in these blocks are most likely legitimate embedded Wi-Fi/NIC modules; treat an unfamiliar MAC as an inventory-correlation task, not an automatic indicator of compromise. [Confirmed — absence of public reports] — whirlpool.net.au forum

Analyst note

a MAC in these blocks identifies a Foxconn-manufactured embedded network interface inside a finished product (often Sony/HP/Samsung gear), not a device branded "Cloud Network Technology." The legal entity is Singapore-registered but China-operated and now amalgamated; OUI data still carries the original name.
