Hi nusenu,
thanks for getting in touch again.
Are there plans to add AS names for these regions as well or will this not improve in the near future (before 2022)?
I have not yet looked at JPNIC in detail. If they provide a feed similar to RIPE, AFRINIC, or APNIC, integrating it should be done pretty quickly. (Same goes for TWNIC and KRNIC, since I am not sure whether their information is mirrored back to APNIC...)
LACNIC is - well - tedious. Perhaps we are going to scrape RIPEstat for missing AS names, where we would have this RIR covered. Personally, I would consider this the last option, but I don't think they will allow us to fetch the complete information from their servers.
(This remains a task for ARIN as well, since we are still missing some country information for suballocations there.)
Having a lot of other ${dayjob}-related things on my plate, I cannot give you an ETA for all of this. Let's hope it won't become 2022. :-)
Sorry for this rather vague answer.
Thanks, and best regards, Peter Müller
