ARP Table not identifying Dell OUI: 74:78:27

[trdeal]

Is it possible to modify or update to a later version the resource which is referenced by ARP table so that I can add missing Vendor mac prefix entries. Using maclookup.app I found that the 74:78:27 was assigned to Dell on 23rd September 2020, so it is not new being nearly three years old. Which raises the question how frequently the vendor mac prefix resource is updated.
