What this result means

These records show the organisation named by the IEEE Registration Authority for each prefix. A match can support device identification, but it does not prove the device model, present owner or network operator. Subsidiaries and acquired product lines may appear under different registry names.

The lookup service tests the most specific assignment first. See OUI, MA-L, MA-M and MA-S explained for the difference between prefix sizes.
