This was suggested by a Piwik chinese user by email:
Hi Piwik, I am a Piwik developer from china, and we have a problem in GEO IP. we found lot of visitors IP where from China was not correct , we suggest Piwik to provide IP database option which is popular in China. Their website is https://www.ipip.net/?l=EN . we hope Piwik to improve the precision of GEO IP . Thanks
This could be done as a plugin on the Marketplace but I also wanted to note the idea here in an issue.
Any update? Is this available?
@dieskim sadly not.I have currently no personal need
I think this would be something for piwik
Only "enhancing" the visitor data with the geo data is easy. But the integration with piwik is a bit more work
