RuggedTek Hangzhou Co., Ltd — C8:C1:3C (MA-L)

RuggedTek Hangzhou Co., Ltd holds a single IEEE MA-L block, C8:C1:3C, registered to an address in the Zhejiang University National Science Park in Hangzhou, Zhejiang Province, China — a university-affiliated technology and startup zone that hosts many of the area's hardware ODMs. The registration is confirmed first-party in IEEE's public OUI listing and reproduced in the Wireshark the Wireshark manufacturer database database, and it is echoed by the usual third-party MAC vendor mirrors (maclookup.app, macvendorlookup.com, hwaddress.com), all of which return the same organization name and Hangzhou address. Beyond the registry record itself, this vendor leaves an unusually thin public footprint: no vendor website resolves for "RuggedTek Hangzhou," there is no discoverable product catalog, and the several similarly-named companies that do surface in search (Ruggtek, RuggedTech Systems, Rugged Tech Co. Ltd) are distinct entities that should not be conflated with this OUI holder. The "RuggedTek" name and the Hangzhou industrial-park location are consistent with the rugged/industrial handheld and tablet segment concentrated in that region, but that is a naming inference, not corroborated device-type evidence, so the actual device type stays Unknown rather than being asserted. No CVEs, CISA advisories, or Shodan exposure reports were found for this organization or for OUI C8:C1:3C, and no deployed device population is identifiable, so the security posture is likewise unknown rather than clean-by-claim. A note on dating: third-party MAC databases display a "first sighting" of 2010-01-05 and a "last modified" of 2015-11-17 for this prefix, but those are database artifacts of the scraping service — IEEE publishes no registration date for OUI/MAC assignments — and must not be presented as an IEEE-sourced registration date.

IEEE assignment

C8:C1:3C → RuggedTek Hangzhou Co., Ltd [Confirmed] — IEEE MA-L (line 594); Wireshark the Wireshark manufacturer database

Registry / block size

MA-L (24-bit OUI; ~16.7M addresses), single block [Confirmed] — IEEE the IEEE MA-L registry; maclookup.app

HQ / country

Zhejiang University National Science Park, Hangzhou, Zhejiang, CN 310013 [Confirmed] — IEEE the IEEE MA-L registry; macvendorlookup.com

Country

China (CN) [Confirmed] — IEEE the IEEE MA-L registry; macvendorlookup.com

Company status

Unknown — no vendor website, corporate registry record, or product catalog discoverable for "RuggedTek Hangzhou Co., Ltd"; the registry entry is the only confirmable trace [Unknown] — no source (searches returned only distinct, similarly-named entities)

Device types

Unknown — the name and Hangzhou industrial-park location are consistent with rugged/industrial handhelds and tablets, but no catalog or corroborating evidence confirms a device type [Unknown] — no source (naming inference only, not asserted)

Vendor website

Unknown — no site resolves for this entity; ruggedtek.com and near-variants belong to unrelated companies (Ruggtek, RuggedTech Systems, Rugged Tech Co. Ltd) [Unknown] — no source

Verified prefix (MA-L, RuggedTek Hangzhou Co., Ltd)

C8:C1:3C [Confirmed] — IEEE the IEEE MA-L registry; hwaddress.com; macvendorlookup.com

Security context

No CVEs, CISA advisories, or Shodan exposure reports found for RuggedTek Hangzhou Co., Ltd or OUI C8:C1:3C; no identifiable deployed device population, so posture is unknown rather than clean [Unknown] — no source

No-IEEE-date note

IEEE's public OUI data (the IEEE MA-L registry columns: Registry, Assignment, Organization Name, Organization Address) publishes NO assignment/registration date. Third-party tools showing a "first sighting" 2010-01-05 / "last modified" 2015-11-17 are reporting database artifacts, not IEEE facts.

Analyst note

A C8:C1:3C address reliably identifies a RuggedTek Hangzhou-registered interface, but with no public product line the OUI alone does not tell you what kind of device it is; treat device-type guesses as unconfirmed.
