About this vendor.

Updated  ·  Confidence: High

A MAC address beginning with 48:5F:99, 28:3A:4D, or 0C:96:E6 belongs to Cloud Network Technology (Samoa) Limited, an IEEE-registered OUI holder that functions as an OEM network-module registration entity within the Hon Hai Precision Industry (Foxconn) corporate group, rather than as a standalone consumer-facing brand.

The company holds a Legal Entity Identifier (LEI 2549001OR2EQQFA3Q216) issued by the Samoa International Finance Authority (registration authority RA000509), incorporated 19 December 2017, with its registered address held via corporate-services agent Vistra (Samoa) Limited — a structure typical of an offshore holding/registration subsidiary rather than an empty shell.

LEI reference data shows the entity is directly and ultimately consolidated by Hon Hai Precision Industry Co., Ltd. (Foxconn), LEI 30030004CM3GSZXX7O56, a relationship dated 29 May 2017. It sits alongside sibling "Cloud Network Technology" OUI-holding entities, including a Singapore Pte. Ltd. (57 MA-L prefixes, already a DONE entry in this registry) and a USA Inc., each registering network hardware for Foxconn-manufactured products.

No device model is documented specifically for the Samoa entity, but a third-party reference describing the Foxconn "Cloud Network Technology" OUI family frames the role generically: the registrant holds the OUI while the network module itself "can be manufactured by an original equipment supplier and installed inside a router, television, computer, streaming device, appliance, or other connected product" — matching the OEM-supplier pattern documented for the Singapore sibling.

The entity's LEI status is LAPSED as of 27 November 2023, which is common for smaller non-trading subsidiaries and not itself a red flag. No CVE, malware, or threat-actor attribution was found for this OUI in a targeted security search; this is an absence-of-evidence result, not a clean-bill guarantee.

Special note
IEEE's public MA-L data publishes no assignment/registration date field; third-party "date registered" values (e.g. 05 April 2018, 13 June 2018) are database-scrape artifacts, not IEEE facts. The company's Samoa incorporation date (19 Dec 2017) is a separate, non-IEEE registry fact.
