Kingston Technology Company, Inc. — 2 prefixes (MA-L)

A MAC address starting with 00:C0:F0 or 00:26:B7 belongs to Kingston Technology Company, Inc., typically seen on 1990s-era Ethernet networking hardware such as the EtheRx line of 10/100 hubs and switches rather than Kingston's better-known memory or USB products.

Both prefixes are confirmed as separate MA-L (24-bit OUI) assignments in the IEEE registry, registered to the same organization at the same Fountain Valley, California address — the exact HQ of Kingston Technology Corporation, the large, well-documented American memory and storage manufacturer founded in 1987.

Kingston's core business today is DRAM modules and USB flash drives, not networking gear, so these OUIs most plausibly trace to Kingston's now-discontinued networking hardware division of the 1990s. No IEEE assignment date exists for either prefix; any third-party "date registered" figure is a database artifact, not an IEEE fact.

No CVE or security advisory found in an August 2026 search ties directly to Kingston's networking hardware or to either OUI specifically. Documented Kingston security history involves unrelated USB flash-drive products (host-side password-bypass flaws, circa 2009-2010), not Ethernet hardware.

IEEE assignment

00:C0:F0 and 00:26:B7 → Kingston Technology Company, Inc., registered Fountain Valley, CA, US [Confirmed] — the IEEE MA-L registry 00C0F0, the IEEE MA-L registry 0026B7

Registry / block size

MA-L (24-bit OUI); two confirmed assignments; no MA-M or MA-S entries found for this organization [Confirmed] — the IEEE MA-L registry, the IEEE MA-M registry, the IEEE MA-S registry

HQ / country

17600 Newhope Street, Fountain Valley, CA 92708, US [Confirmed] — the IEEE MA-L registry 00C0F0

Company status

active — Kingston Technology Corporation, founded 1987 by John Tu and David Sun [Confirmed] — https://en.wikipedia.org/wiki/Kingston_Technology

Device types

1990s Ethernet networking hardware (EtheRx hubs/switches) plausible for these OUIs; parent company's current products are DRAM modules and USB flash drives [Likely] — https://www.ebay.com/p/74066774, https://en.wikipedia.org/wiki/Kingston_Technology

Notable products

EtheRx 10/100 Ethernet hub/switch line (e.g. KND1610TX), DRAM memory modules, DataTraveler USB flash drives [Likely] — https://www.ebay.com/p/74066774

Verified sample prefixes (both MA-L, Kingston Technology Company, Inc.)

00:C0:F0, 00:26:B7 [Confirmed] — the IEEE MA-L registry

Registration date

Unknown — IEEE's public OUI data contains no assignment/registration date field; any third-party "date registered" is a database artifact [Confirmed] — the IEEE MA-L registry, https://www.adminsub.net/mac-address-finder/kingston

Special note

Two independently-registered MA-L blocks at the same address confirm this is not a bare single-OUI shell registration; no shared-base IEEE-RA allocation is involved, and no third OUI is confirmed beyond these two [Confirmed] — the IEEE MA-L registry

Related vendors

none confirmed

Analyst note

A MAC starting 00:C0:F0 or 00:26:B7 identifies Kingston Technology Company, Inc. hardware, most plausibly from its discontinued 1990s networking division rather than its current memory/storage product lines; no security or malware association was found for either prefix.
