Solidigm Technology — 2 prefixes (MA-L)

Solidigm Technology holds two separate IEEE MA-L blocks, AC:A3:2F and C8:D6:B7, both registered to the same Longmont, Colorado address. Solidigm is not a startup shell registration — it is the SK hynix-owned entity formed from SK hynix's acquisition of Intel's NAND flash and SSD business, a deal that closed in two phases (the first in December 2021, the final phase completing March 27, 2025). The company designs and ships enterprise and datacenter SSDs, inheriting product lines and engineering from the former Intel storage group. Two independently-assigned OUI blocks under one org name is itself a substance signal beyond a bare single-OUI registration, and is corroborated by an independent third-party MAC-vendor lookup returning the same organization name for both prefixes. Solidigm also runs its own security-advisory program, publishing CVE-numbered SSD firmware advisories (e.g., a March 2025 advisory spanning CVE-2024-47967 through CVE-2024-47974), and Dell has separately issued a PowerEdge advisory (DSA-2022-203) for Solidigm SSD firmware vulnerabilities — further evidence this is an actively maintained hardware vendor rather than a dormant registrant. No source ties either specific OUI to an observed Ethernet-attached device, so device type for these particular blocks stays unconfirmed.

IEEE assignment

AC:A3:2F and C8:D6:B7 → "Solidigm Technology," registered 1921 Corporate Center Circle, Suite 3B, Longmont, CO 80501, US [Confirmed] — IEEE MA-L (sourced from https://standards-oui.ieee.org/oui/oui.csv)

Registry / block size

MA-L (24-bit OUI) × 2 distinct blocks under the same org name; no MA-M or MA-S (28-/36-bit) blocks found for this org [Confirmed] — the IEEE MA-L registry, the IEEE MA-M registry, the IEEE MA-S registry (no matches in the latter two)

Registration dates

not published. IEEE's MA-L data has no date column; do not infer or attribute a "date registered" to IEEE for either block. [Confirmed] — IEEE the IEEE MA-L registry column set (Registry, Assignment, Organization Name, Organization Address only)

Company background

Solidigm is the SK hynix-owned entity formed from SK hynix's acquisition of Intel's NAND memory and SSD business; first phase closed December 2021, final phase closed March 27, 2025 [Confirmed] — https://news.solidigm.com/en-WW/212943-sk-hynix-completes-the-first-phase-of-intel-nand-and-ssd-business-acquisition/, https://www.tomshardware.com/pc-components/ssds/intel-and-sk-hynix-close-nand-business-deal-intel-gets-usd1-9-billion-sk-hynix-gets-ip-and-employees

Registered address corroboration

1921 Corporate Center Circle, Suite 3B, Longmont, CO — confirmed as an active Solidigm office site (alongside HQ in Rancho Cordova, CA, and a San Jose office) [Likely] — https://hwaddress.com/company/solidigm/

Company status

active [Confirmed] — https://www.solidigm.com

Vendor-name corroboration

independent third-party lookup (macvendors.com) returns "Solidigm Technology" for both AC:A3:2F and C8:D6:B7, corroborating the name mapping only (no date taken from this source) [Confirmed] — https://api.macvendors.com/AC:A3:2F:00:00:00, https://api.macvendors.com/C8:D6:B7:00:00:00

Device types

Unknown — no sourced evidence ties AC:A3:2F or C8:D6:B7 specifically to an observed Ethernet-attached product; Solidigm's general business is enterprise/datacenter SSDs, but whether these OUIs sit on drives, enclosure-management NICs, or general corporate equipment is unconfirmed [Unknown]

Notable products

enterprise/datacenter SSDs (inherited Intel NAND/SSD product lines) [Likely] — https://www.solidigm.com

Security context

Solidigm publishes its own CVE-numbered SSD firmware advisories, e.g. a March 2025 advisory covering CVE-2024-47967–CVE-2024-47974; Dell separately issued DSA-2022-203 for Solidigm SSD vulnerabilities in PowerEdge servers [Confirmed] — https://www.solidigm.com/support-page/support-security.html, https://www.dell.com/support/kbdoc/en-us/000203265/dsa-2022-203-dell-poweredge-server-security-update-for-solidigm-ssd-vulnerabilities

Analyst note

two independent MA-L assignments to the same active, security-advisory-publishing SSD vendor clears the abstention bar for a single-OUI shell registration; device-type claims for these two specific prefixes should stay unconfirmed pending a packet-capture or forum sighting.
