The question "which ASN are the clients coming from?" was exactly the reason I revived AWFFull — the new version adds an ASN table based on the DB-IP ASN Lite database :-)

To your point about it maybe being a paid feature: the DB-IP Lite files are free (CC-BY), so the ASN part doesn't have to cost anything — it's just not what the MaxMind-oriented tooling usually reaches for.

Sweet! After reading your reply I had a look and downloaded the DB-IP ASN Lite db also. From before I had the DB-IP City Lite db. And then making GoAccess use the ASN db was just a matter of adding the same --geoip-database argument again to GoAccess that I already use with the city db file path, but with the ASN db file path. As per the manual https://goaccess.io/man which even includes exactly using both city and ASN db together as an example :D

This is why it’s so great to share experiences on HN :) I wasn’t really planning on looking further into how to set up the ASN part but then after your comment I basically had no choice other than to have a look to see if the ASN Lite db file was the missing part and it was :D Thank you :)
