ProCurve Networking by HP — 9 prefixes (MA-L)

ProCurve Networking by HP was Hewlett-Packard's enterprise networking division, and the name appears on nine MA-L OUI blocks in the IEEE registry (00:16:B9, 00:1B:3F, 00:23:47, 00:24:A8, 00:25:61, 00:26:F1, B4:39:D6, C0:91:34, F0:62:81). Eight of the nine are registered to 60 Alexandra Terrace, Singapore 118502; the lone exception, 00:16:B9, carries the older Roseville, California address (8000 Foothills Blvd, Roseville, CA 95747, US) where HP's networking business originated in 1979. The ProCurve brand was active roughly 1998–2010 and was applied chiefly to managed Ethernet switches across edge, distribution, core, datacenter, and blade form factors, along with routers, wireless access points (after HP's 2008 acquisition of Colubris Networks), and network security appliances. The brand is now defunct: HP renamed the unit "HP Networking" in 2010 after acquiring 3Com, and in 2015 the networking operations were folded into Aruba Networks under Hewlett Packard Enterprise, marketed today as HPE Aruba Networking. For traffic analysis, a ProCurve MAC reliably indicates managed enterprise/campus infrastructure — a switch, router, or AP — rather than a consumer or IoT endpoint; these devices support MAC authentication, ACLs, and NAC. As with every IEEE OUI, no registration date is published by IEEE; any "date registered" shown on third-party lookup tools is a database artifact, not an IEEE fact.

IEEE assignment

9 MA-L prefixes → "ProCurve Networking by HP" [Confirmed] — IEEE MA-L

Registry / block size

MA-L (24-bit OUI); 9 IEEE prefixes found, no MA-M or MA-S/oui36 blocks under this name [Confirmed] — IEEE the IEEE MA-L registry / the IEEE MA-M registry / the IEEE MA-S registry (no hits in the latter two). NOTE: IEEE's public OUI data publishes NO assignment/registration date (the IEEE MA-L registry columns are only Registry, Assignment, Organization Name, Organization Address); any "date registered" on third-party tools is a database artifact, not an IEEE fact.

HQ / country

SG (primary registry country); US for the single Roseville-registered block [Confirmed] — IEEE MA-L

Company / brand status

defunct brand. Active ~1998–2010; renamed "HP Networking" in 2010 after the 3Com acquisition; networking moved under Aruba Networks (HPE) in 2015, now HPE Aruba Networking [Confirmed] — en.wikipedia.org/wiki/ProCurve, en.wikipedia.org/wiki/HPE_Networking

Parent company

Hewlett-Packard (HP), now Hewlett Packard Enterprise (HPE); networking division originated at HP Roseville, CA in 1979 [Confirmed] — en.wikipedia.org/wiki/ProCurve

Device types

managed Ethernet switches (edge, distribution, core, datacenter, blade), routers, wireless access points (post-2008 Colubris acquisition), network security appliances — enterprise/campus LAN infrastructure [Confirmed] — en.wikipedia.org/wiki/ProCurve, en.wikipedia.org/wiki/HPE_Networking

Notable deployment

ProCurve 2524 switches were used aboard the International Space Station [Likely] — en.wikipedia.org/wiki/ProCurve

Vendor site

no standalone ProCurve domain remains; successor landing page is https://www.hpe.com/us/en/networking.html [Likely] — hpe.com

Security context

enterprise-grade managed hardware; supports MAC authentication, ACLs, IPS, and NAC (ClearPass). A ProCurve OUI in traffic = managed infrastructure (switch uplink/management port, router, or AP), not a consumer/IoT endpoint

Analyst note

"ProCurve Networking by HP" is a legacy brand name; newer HPE switches register under "Hewlett Packard Enterprise" or "Aruba" OUIs, so this entry will not cover the full HPE switch fleet — treat it as the ProCurve-era subset.
