Both AS lack an "aut-num" object in JPNIC, which is why there is no parseable information
for them at hand in there. Not sure where RIPEstat gets their description from...

Anyways, ARIN, LACNIC and a better approach to missing data is on my list for next week.
I'll see what we can to then.

Thanks, and best regards,
