Variscite LTD holds two MA-L blocks (about 33.5 million addresses) registered to "Variscite LTD" at 15 Ismargad St, Kiryat Gat, Israel 8202041 — F8:DC:7A and 54:0B:B6 — both carrying that same registry address. Variscite is a long-established Israeli embedded-hardware company that designs and manufactures ARM-based System-on-Modules (SoMs): compact compute modules in the VAR-SOM, DART, and VAR-SMARC families built on NXP i.MX 6/7/8/9 and TI Sitara AM62 SoCs. It does not ship finished consumer products; its modules are integrated by OEMs onto carrier boards inside industrial IoT gateways, medical devices, agricultural and control systems, multimedia players, and point-of-sale equipment, where the MAC-addressed interface is the SoM's onboard Wi-Fi or Ethernet (or an Ethernet PHY on the carrier board). The analyst point is the module pattern: a Variscite OUI identifies a Variscite SoM regardless of the brand on the enclosure, so it flags an ARM embedded-Linux device — most often industrial, medical, or IoT — rather than a specific product. Variscite SoMs carry NXP hardware security (ARM TrustZone, High Assurance Boot/HABv4, the CAAM crypto accelerator, and on i.MX 9 the EdgeLock secure enclave), newer SMARC modules add an embedded TPM aimed at EU Cyber Resilience Act and FIPS 140-3 readiness, and in February 2025 Variscite partnered with Check Point to offer the Quantum IoT Protect Nano Agent across its SoM line. No Variscite-specific CVE surfaced in this research pass; the threat surface is standard embedded Linux (kernel, BSP drivers, OTA channel). For triage, a Variscite OUI in ARP/DHCP means an ARM SoM-based embedded device built on Variscite silicon-on-module — classify it as industrial/embedded, not as a specific brand, and treat it as the device class that warrants firmware-update and BSP-currency checks.
- IEEE assignment
- 2 prefixes → Variscite LTD, registered Kiryat Gat, Israel [Confirmed] — IEEE MA-L (file:enrichment/registries/oui.csv lines 7172, 22929)
- Registry / block size

- Verified prefix sample (all MA-L)
- F8:DC:7A, 54:0B:B6 [Confirmed] — file:enrichment/registries/oui.csv
- Special note
- Module-OUI flag. A Variscite OUI identifies a Variscite SoM regardless of the brand on the enclosure; the modules are embedded by OEMs into industrial/medical/IoT hardware, so a Variscite OUI indicates an ARM embedded-Linux device of that class, not a specific product. The IEEE registry publishes no assignment dates, so none is stated here. [Confirmed]
- Security context
- Variscite SoMs include NXP hardware security — ARM TrustZone, High Assurance Boot (HABv4), CAAM crypto acceleration, and the EdgeLock secure enclave on i.MX 9; newer VAR-SMARC modules add an embedded TPM targeting EU Cyber Resilience Act (CRA) and FIPS 140-3 readiness. In February 2025 Variscite partnered with Check Point Software to offer Check Point Quantum IoT Protect (Nano Agent) across its SoM line (firmware-level protection vs. DoS, malware, botnets, zero-day exploits). OTA/update ecosystem partners include Foundries.io, Sequitur Labs, JFrog (formerly Upswift), and Mender. No Variscite-specific CVE was found in this research pass; residual risk is the standard embedded-Linux surface (kernel, BSP drivers, OTA channel).

- Analyst note
- A Variscite OUI in ARP/DHCP means an ARM SoM-based embedded device built on Variscite silicon-on-module — most often industrial, medical, or IoT hardware running embedded Linux. Classify it as industrial/embedded, not a specific brand, and treat it as the device class that warrants firmware-update and BSP-currency checks. The brand on the enclosure is unknown from the OUI.
