Ipip Database plugin is not included in any Countly edition. You can download the plugin from here to upload and enable in your own Countly instance.
Countly depends on Maxmind database for IP geo-location, the process of mapping an IP address to corresponding physical location as city and country. However, this database is not accurate enough to be used for applications with majority of their userbases in China.
This plugin makes Countly use IPIP database for the IP geo-location process.
