New H3C — ~134 prefixes (MA-L); enterprise networking, OUI = brand (complex 3Com/HP/HPE/Unigroup lineage)
Summary
- // what this is
- New H3C Technologies is registered to MAC prefix
1C:AB:34and 133 more in the IEEE OUI database. When a device's MAC address begins with1C:AB:34, that block was registered by New H3C Technologies — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- A New H3C OUI in ARP/switch/DHCP tables is enterprise/campus infrastructure or a server — a high-value managed asset, especially common in China/APAC networks; the OUI maps to the H3C brand, not HPE/Aruba.
About this vendor.
New H3C holds about 134 MA-L blocks registered as "New H3C Technologies Co., Ltd" at 466 Changhe Road, Binjiang District, Hangzhou, Zhejiang, China — by far the largest registrant in this batch, with an aggregate space of roughly 2.2 billion addresses. Verified samples include 1C:AB:34, 30:7B:AC, 74:EA:C8, 38:AD:8E, 04:40:A9, and 90:5D:7C. These OUIs appear on campus and enterprise switches, routers, Wi-Fi access points, firewalls, servers, storage, and hyper-converged systems. H3C has one of the most tangled lineages in networking: it was incorporated in 2003 as a Huawei-3Com joint venture, 3Com bought out Huawei's stake (2007), HP acquired 3Com (announced 2009-11-12 at $7.90/share, ~$2.7B enterprise value, closing 2010), HP/HPE then sold 51% of a newly formed "New H3C" to Tsinghua Holdings' Unisplendour (~$2.3B net, closing May 2016) while retaining 49%, and on 2023-05-26 HPE signed an agreement to sell its remaining 49% to Unisplendour International (UNIS), with Caixin reporting a $3.5B cash price. The OUIs sit with the present-day New H3C entity, not with HPE/Aruba. For triage, a New H3C OUI is enterprise/campus infrastructure or a server — a high-value managed asset, especially common in China/APAC networks — and the OUI maps to the H3C brand, so do not infer HPE/Aruba despite the shared history.
