HP Inc. — ~42 (HP Inc.) + ~150 (legacy Hewlett Packard) prefixes (MA-L)

The canonical slug vendor-hp derives from the IEEE registrant string "HP Inc." — the slug normaliser strips the "Inc" token, leaving "hp" — so this entry is the PCs-and-printers half of the company that split on 1 November 2015 into HP Inc. and Hewlett Packard Enterprise. The OUI footprint reflects that history in a way that matters for enrichment. Only about 42 blocks carry the clean "HP Inc." registrant string, all 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. An HP printer or an older HP PC will therefore 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 covers consumer and commercial PCs and laptops (EliteBook, ProBook, Pavilion, Spectre, Omen, OmniBook, Z/ZBook workstations) and the large LaserJet/OfficeJet/DeskJet/ENVY printer line. All registrations here are MA-L; no MA-M or MA-S blocks exist for any HP entity. For triage, an HP printer OUI on a user VLAN is normal, but it is worth checking against the print-server inventory for rogue-printer detection, and HP LaserJet firmware carries a critical 2025 RCE (CVE-2025-26506) that makes prompt patching policy material on flat segments. This entry is the client/printer side only — servers, networking, storage, and Aruba live under the separate HPE entry. Data-quality trap: a prior master entry exists under the non-canonical key vendor-hp-inc for this same registrant; the checker should reconcile (rename to vendor-hp or alias) rather than double-publish.

IEEE assignment

~42 prefixes → HP Inc. (Spring, TX, US) + ~150 legacy prefixes → Hewlett Packard [Confirmed] — IEEE MA-L (the IEEE MA-L registry local snapshot: exactly 42 "HP Inc." rows, 150 "Hewlett Packard" rows)

Registry / block size

MA-L only; HP Inc. registrant ~42 blocks (local the IEEE MA-L registry); maclookup.app reports ~43 — minor count drift expected as the registry updates. No MA-M (the IEEE MA-M registry) or MA-S (the IEEE MA-S registry) assignments exist for any HP entity. [Confirmed assignments] — IEEE MA-L, maclookup.app (IEEE-derived; third-party counts are a current snapshot and drift). 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 (e.g. maclookup.app shows "26 July 2019") is a database artifact, not an IEEE fact.

HQ / country

10300 Energy Dr (also "10300 Energy Drive"), Spring, TX 77389, US — the single modern HP Inc. address across all 42 current blocks. Legacy "Hewlett Packard" blocks are multi-valued (e.g. 11445 Compaq Center Drive, Houston, TX; oldest blocks at Palo Alto / Cupertino MS 42LE addresses) and belong to the separate legacy registrant string.

Special note

Most legacy "Hewlett Packard" blocks predate the 2015 split and were not cleanly re-attributed; only ~42 carry the "HP Inc." string. The three IEEE registrant strings — "HP Inc.", "Hewlett Packard", "Hewlett Packard Enterprise" — produce three distinct slugs (vendor-hp, vendor-hewlett-packard, vendor-hewlett-packard-enterprise). "HP Inc." and legacy "Hewlett Packard" are both the PCs/printers side; neither is HPE.

Slug / coverage trap

A finalized master entry already exists under the non-canonical key vendor-hp-inc ("HP Inc. (+ legacy Hewlett Packard)", DONE 2026-06-06) covering this same registrant. The NEXT-BATCH queue flagged vendor-hp as uncovered because the canonical slug for "HP Inc." is hp, not hp-inc. Reconcile (rename the master key to vendor-hp or add an alias/redirect) rather than publishing two pages for the same vendor.

Security context

HP LaserJet firmware carries CVE-2025-26506 (CVSS:4.0 9.2, Critical) — unauthenticated network-reachable stack buffer overflow via malicious PostScript print jobs on LaserJet Pro/Enterprise/Managed; HIGH attack complexity; patched via HP Security Bulletin HPSBPI04007; NOT on CISA KEV and no verified public PoC as of June 2026. Companion CVE-2025-26507/26508 (CVSS 8.3 each). Historical: CVE-2021-39238 (High) font-parsing flaw across 150+ MFP models, patched Nov 2021. HP Wolf Security data: only ~36% of IT teams patch printer firmware promptly.

Analyst note

An "HP Inc." MAC on the wire is typically a consumer/commercial PC/laptop or a printer/MFP — routine on user and print VLANs, not enterprise infrastructure (no iLO/switches; that's HPE). A printer OUI on a user VLAN is normal but worth verifying against print-server inventory for rogue-printer detection; given CVE-2025-26506, treat unpatched HP printers on flat/uncontrolled segments as a lateral-movement risk and enforce prompt firmware patching.
