This plugin adds support for MaxMind GeoIP2 database.
Currently supported databases:
will this geoip2-plugin will work flawlessly within piwik (which has already geoip1 integrated)?
It was working as core (mentioned erlier PR https://github.com/piwik/piwik/pull/10431 ) and it's currently working without problems on my company instance using current 3.x-dev branch
will there be any conflicts between both?
None observed, it shows as another Location Provider
how do I know which data piwik uses really?
Check your settings - currently used location provider is marked
(on screen there are unknown values because site was accessed from intranet IP address)
You can also reattribute older data using console command:
do geoip2 plugin benefit from piwiks autofetch/-update for geoip1 databases?
At this time - no, but it is planned as soon as i get access to Maxmind account so i can test it.
