Dear Maintainer, The current version of 'asn', as shipped with Debian, contains a bug due to a changed URL in an API. This specifically targets the '-g' option. The cause and fix are known and documented here: https://github.com/nitefood/asn/issues/89 Description by the author: Apparently the RIPE IPmap API URL changed. I'll push the fix shortly, but in the meantime you can try changing this line from: ipmap_output=$(docurl -m15 -s "https://ipmap.ripe.net/api/v1/locate/all?resources=$ipmap_targets") to ipmap_output=$(docurl -m15 -s "https://ipmap-api.ripe.net/v1/locate/all?resources=$ipmap_targets") and bulk geolocation should be working fine. Can this fix be added in the package please ? Thanks !
