Hello Peter,
All location databases and their corresponding database.txt dumps generated after Fri, 9 Jul 2021 23:10:48 UTC should now include AS names for ARIN space. Just thought you might want to know. :-)
I do indeed, thank you for the update and the notification!
Please drop us a line here in case of any questions, bugs, or comments.
I'll be able to check the improved data coverage once the torproject updated to a version containing the data and will be able to report back here and maybe we can even tackle the LACNIC region as well.
kind regards, nusenu
