Hi,
I've been in contact with upstream (ipfire).
Please update to an ipfire database version generated after 9 Jul 2021 23:10:48 UTC this should solve the major part of the issue, at least for ARIN space which was missing.
I would appreciate if you update the db file regularly (ideally automatically) and allow users to easily learn when you update and what version you use.
Thanks for improving onionoo's ASN data.
kind regards, nusenu
