Hewlett Packard Enterprise is the enterprise-infrastructure half of the 2015 HP split, and its MAC footprint is about 170 MA-L blocks that now all carry the single IEEE Organization Name "Hewlett Packard Enterprise" — covering both HPE's own servers/iLO management controllers and the wireless/switching gear of the acquired Aruba brand. This is a change worth noting: the blocks historically associated with Aruba (including the canonical Aruba OUI 00:0B:86) currently render in IEEE data under "Hewlett Packard Enterprise," reflecting a registry consolidation reflected in 2024. The string "Aruba, a Hewlett Packard Enterprise Company" (and the older "Aruba Networks") survives mainly as a Wireshark display alias and in lagging third-party lookup tools — not as the current IEEE registrant string — so tools that show "Aruba" are reading the Wireshark manuf note, while the raw IEEE Organization Name is "Hewlett Packard Enterprise." HPE acquired Aruba in 2015 and, more recently, Juniper Networks (that deal closed 2 July 2025), making Juniper a sibling brand within HPE Networking. Registered addresses cluster around Santa Clara (3333 Scott Blvd; 6280 America Center Dr). On the wire, an HPE OUI usually marks a ProLiant/Apollo server or its iLO out-of-band management port, an Aruba-lineage AP/controller/CX switch, or legacy Hewlett-Packard server gear; switching also carries the former 3Com/H3C lineage. For triage, all are expected on managed segments; an unexpected Aruba-lineage AP MAC can flag a rogue or shadow-IT access point.
- IEEE assignment
- ~170 prefixes → "Hewlett Packard Enterprise" (the single current IEEE Organization Name, covering both HPE server/iLO blocks and the former Aruba wireless/switching blocks) [Confirmed] — IEEE MA-L (IEEE-derived via maclookup.app, which separates the IEEE Organization Name from the Wireshark alias)
- Registry / block size
- MA-L; ~170 blocks (~2.85B addresses) all under "Hewlett Packard Enterprise" [Confirmed assignment] — maclookup.app (IEEE-derived; count is a current third-party snapshot and drifts). NOTE: IEEE's public OUI data publishes NO assignment/registration date (oui.csv columns are only Registry, Assignment, Organization Name, Organization Address); any "date registered" from third-party tools is a database artifact, not an IEEE fact.
- HQ / country
- 3333 Scott Blvd and 6280 America Center Dr, Santa Clara, CA, US (some blocks list Santa Clara CA 95054) [Confirmed] — IEEE MA-L
- Company status
- active; created in the 2015 HP split; acquired Aruba (2015) and Juniper Networks (closed 2025-07-02) [Confirmed] — hpe.com
- Device types
- ProLiant/Apollo servers, iLO management controllers, HPE/Aruba switches (incl. former 3Com/H3C lineage), Aruba-lineage access points and controllers [Confirmed] — maclookup.app
- Notable products

- Verified prefix sample (all render as "Hewlett Packard Enterprise" in current IEEE data)
- 90:20:C2, D0:4D:C6, 1C:28:AF, F4:2E:7F, 6C:C4:9F, 34:8A:12, 24:62:CE, EC:67:94, EC:02:73, EC:50:AA, plus the canonical historic Aruba OUI 00:0B:86 [Confirmed] — maclookup.app
- Special note
- REGISTRANT-STRING CORRECTION. Prefixes previously labeled "Aruba-registered" (D0:4D:C6, 1C:28:AF, F4:2E:7F, 6C:C4:9F, 34:8A:12, 24:62:CE, EC:67:94, EC:02:73, EC:50:AA) and the canonical Aruba OUI 00:0B:86 all currently carry the raw IEEE Organization Name "Hewlett Packard Enterprise." "Aruba, a Hewlett Packard Enterprise Company" / "Aruba Networks" persists as a Wireshark display alias and in lagging third-party tools, not as the current IEEE registrant string. [Confirmed] — maclookup.app
- Related vendors
- HP Inc. (sibling); Aruba (wireless brand/lineage within HPE, acquired 2015; now under the HPE IEEE registrant); Juniper Networks (acquired, closed 2025-07-02); 3Com/H3C (legacy switching lineage)
- Analyst note
- An HPE OUI typically marks a server or its iLO management port; an Aruba-lineage OUI marks enterprise wireless/switching infrastructure — both expected on managed segments, and an unexpected Aruba-lineage AP MAC can indicate a rogue or shadow-IT access point. Note that tools displaying "Aruba" are reading the Wireshark alias; the IEEE registrant is "Hewlett Packard Enterprise."
