HPRO — 2 prefixes (MA-L)
Summary
- // what this is
- HPRO is a registered holder in the IEEE OUI (MAC address) database. An OUI identifies the maker of a device's network hardware — which is not always the brand on the device.
- // analyst note
- Two confirmed same-name OUI assignments plus a same-address sibling registration are the substance basis for this entry; company identity beyond the bare 'HPRO' registry string is a Likely inference (Harman Professional), not IEEE-confirmed. Do not conflate with 'HPRO-Video' or with the unrelated Taipei-based 'HIGHPRO INTERNATIONAL R&D CO.'
About this vendor.
HPRO holds two confirmed MA-L OUI assignments — 50-EE-87 and 60-A1-FE — both registered to the identical organization name "HPRO" at 8500 Balboa Blvd, Northridge, CA 91329, US. That address is not disclosed by IEEE as belonging to any larger corporate name, but it independently and repeatedly resolves, across an FCC equipment filing, a Yelp business listing, a Dun & Bradstreet company profile, and a Northridge chamber-of-commerce directory entry, to Harman Professional, Inc., the Samsung-owned professional audio/AV division of Harman International Industries (parent to JBL Professional, AMX, BSS, Crown, and Soundcraft). Harman's own marketing materials use "HPro" as informal shorthand for "Harman Professional," reinforcing the inference — though this remains an inference rather than an IEEE-published fact, since the registry field itself records only the bare string "HPRO." A third, separately-named OUI, D0-C6-BE ("HPRO-Video"), shares the same building address but carries a distinct organization-name registration; it is treated here as a likely sibling brand rather than folded into this entry. No device model, product line, or CVE has been publicly tied to any of the three prefixes.

- Related but distinct registration (not part of this entry)
- D0-C6-BE → org name "HPRO-Video", same building address, separate IEEE org-name string — kept as a sibling/adjacent registration, not merged into vendor-hpro [Confirmed] — the IEEE MA-L registry
