I get many matches on this particular OUI. Are all of these records current or what?

I believe this the matches are technically correct based on a search parameter of 30:0A:60 , however, I have identified a bug that that would cause the same results to be shown even if you searched a full MAC address. Essentially, the MA-M registry is a 28 bit registry but the entries are going in as /24 and shouldn't be. I will work on this and push out an update.
