HP Inc. is the PCs-and-printers half of the company that split on 1 November 2015 into HP Inc. and Hewlett Packard Enterprise, and its OUI footprint reflects that history in a way that matters for enrichment. Only about 42 blocks carry the clean "HP Inc." registrant string (at 10300 Energy Dr, Spring, TX); the bulk of HP's older allocations — about 150 blocks — remain under the legacy "Hewlett Packard" name and were never cleanly re-attributed at the split. The practical consequence is that an HP printer or an older HP PC will frequently resolve to the legacy name rather than to "HP Inc.," so both strings should be normalized to HP Inc. in the pipeline. Device-wise this entry covers consumer and business PCs and laptops (EliteBook, ProBook, Pavilion, Spectre, Omen) and the large LaserJet/OfficeJet/DeskJet printer line. All registrations here are MA-L. For triage, an HP printer OUI on a user VLAN is normal, but it's worth checking against the print-server inventory for rogue-printer detection. This entry is the client/printer side only — servers, networking, and Aruba live under the separate HPE entry.
- IEEE assignment
- ~42 prefixes → HP Inc. (Spring, TX, US) + ~150 legacy prefixes → Hewlett Packard [Confirmed] — IEEE MA-L
- Registry / block size
- MA-L only; HP Inc. registrant ~42 blocks; legacy Hewlett Packard registrant ~150 blocks [Confirmed assignments] — maclookup.app (IEEE-derived; counts are a current third-party snapshot and drift). 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
- 10300 Energy Dr, Spring, TX 77389, US (modern HP Inc. address). Legacy "Hewlett Packard" blocks are multi-valued (e.g. 9C:7B:EF lists 11445 Compaq Center Drive, Houston, TX; oldest 1990s blocks associate with 3000 Hanover Street, Palo Alto, CA) [Confirmed] — IEEE MA-L

- Device types
- consumer/business PCs and laptops, printers/MFPs [Confirmed] — maclookup.app
- Notable products
- EliteBook, ProBook, Pavilion, Spectre, Omen (clients); LaserJet, OfficeJet, DeskJet (printers)
- Verified prefix sample
- 64:4E:D7 → HP Inc.; 9C:7B:EF → legacy Hewlett Packard [Confirmed] — maclookup.app
- Special note
- Most legacy "Hewlett Packard" blocks predate the 2015 split and were not cleanly re-attributed; only ~42 blocks carry the "HP Inc." string. Normalize both to HP Inc. "Hewlett-Packard Company" is the historical predecessor name (a distinct current hyphenated IEEE registrant string was not independently confirmed this round — [Unverified]). Distinct from the separate "Hewlett Packard Enterprise" (HPE) registrant. [Confirmed] — maclookup.app/vendors/hewlett-packard
- Related vendors
- Hewlett Packard Enterprise (sibling, same 2015 split); Hewlett-Packard Company (historical predecessor)
- Analyst note
- Treat both "HP Inc." and legacy "Hewlett Packard" OUIs as HP Inc. client/printer assets; a printer OUI on a user VLAN is normal but worth verifying against print-server inventory for rogue-printer detection.
