besides not being able to provide IPv6 country data there is an address range missing from the USofA for cloudflare IP4
Please arrange for the XG database to be updated.
Also when will the XG country database include IPv6?
I'll check this with the concerned team and get it updated accordingly.
XG uses MAXMINDGeoIP database for GeoIP ip2country. Upon checking IP classification for 188.8.131.52/16 subnet, found that MAXMIND database does not have details for any IP for the said subnet.
I'd request to raise a classification request with MAXMIND team, once their database will get updated we can let the concerned team know to update Sophos ip2country DB accordingly.
I have submitted a request via email as requested by their site.
