Internet Exchange route servers would be another case that would appear
unused to the broader internet, but shouldn't use a private ASN.

I'm amazed at the number of AS numbers that are assigned, but not actively

'not actuvely being used' ... how would you (or anyone) know? what if they
were used only on some internal part of a large public network which never
leaked beyond their borders/uses? What if the ASN is used on a large
private network? (for instance.. where I know of several such things).
