QLogic Corporation — 6 prefixes (MA-L)

QLogic Corporation holds six confirmed MA-L OUI assignments (00:0E:1E, 00:1B:32, 00:24:FF, 00:C0:DD, 00:E0:8B, F4:E9:D4), all registered directly to "QLogic Corporation" rather than to a subsidiary or reseller — a multi-prefix footprint that clears the single-OUI-shell bar. Founded in 1992 as a spinoff from Emulex, QLogic built its business on enterprise storage-networking hardware: Fibre Channel host bus adapters (HBAs), Fibre Channel-over-Ethernet converged network adapters, iSCSI adapters, Ethernet NICs, and the SANbox line of Fibre Channel switches — datacenter and SAN gear, not consumer devices. Five of the six blocks carry the company's long-standing Aliso Viejo, CA registry address; one (00:E0:8B) sits at a nearby Laguna Hills Dr. address, and one (00:C0:DD) is registered to an Eden Prairie, MN address, likely reflecting a different site or acquired product line at registration time — the exact reason isn't confirmed in available sources. QLogic traded on NASDAQ as QLGC until Cavium, Inc. acquired it for roughly $1B in 2016; Cavium itself was folded into Marvell Technology Group in 2018, and QLogic-branded HBA/CNA product documentation is now hosted under marvell.com. A lookalike to avoid when enriching nearby entries: 00:14:05 is registered to "OpenIB, Inc." (address reads c/o QLogic, Mountain View) and was excluded here as not an exact QLogic org match. As with all IEEE MA-L data, no registration date is published for any of the six blocks; any per-prefix "date registered" surfaced by third-party lookup tools is a database artifact, not an IEEE fact.

Company status

acquired — Cavium, Inc. bought QLogic (~$1B, announced June 2016 / closed August 2016); Cavium merged into Marvell Technology Group in 2018; QLogic-branded product lines continue under Marvell today [Confirmed] — https://www.sec.gov/Archives/edgar/data/0000918386/000119312516682628/d239663dex992.htm , https://www.fibre-systems.com/news/cavium-diversifies-qlogic-acquisition , https://www.sec.gov/Archives/edgar/data/1175609/000156459018004100/cavm-10k_20171231.htm

Device types

Fibre Channel HBAs, Fibre Channel-over-Ethernet CNAs, iSCSI adapters, Ethernet NICs, SANbox Fibre Channel switches — enterprise/datacenter SAN gear, not consumer hardware [Confirmed] — https://en.wikipedia.org/wiki/QLogic , https://www.marvell.com/content/dam/marvell/en/public-collateral/fibre-channel/marvell-fibre-channel-adapters-qlogic-series-2800-user-guide.pdf

Device-context corroboration

a live 00:C0:DD-prefixed MAC observed on a QLogic QLE8142 Ethernet adapter; SANbox 5800V/5602 Fibre Channel switches documented as retail/resale products [Likely] — https://forums.freebsd.org/threads/qlogic-qle8142-ibmx-unstable-on-freebsd-and-windows.76345/ , https://itinstock.com/qlogic-sanbox-5800v-24-port-active-8gb-fc-1u-switch-1x-psu-sb5800v-08a8-80707-p.asp

Dates caveat

IEEE's public MA-L registry publishes no per-OUI assignment/registration date; maclookup.app's displayed per-prefix "registration dates" and aggregate "22 April 1998" figure are third-party database artifacts, not IEEE facts, and are not recorded here as dates

Security context

legitimate enterprise B2B storage-networking hardware; no elevated abuse/botnet risk profile found in sources checked; current firmware/driver support and CVEs for these product lines are now filed under Marvell rather than QLogic [Likely] — https://www.sec.gov/Archives/edgar/data/1175609/000156459018004100/cavm-10k_20171231.htm , https://www.marvell.com/content/dam/marvell/en/drivers/release-2023-04-21/documentation/marvell-fibre-channel-adapters-qlogic-series-qconvergeconsole-cli-user-guide.pdf

Analyst note

an OUI hit on any of these 6 prefixes indicates legacy or still-in-service Fibre Channel/CNA/iSCSI enterprise hardware, most likely inside a corporate SAN or server — not a consumer/IoT device. [Confirmed reasoning from device-type sources above]
