This was requested a few times over the years by email and in the forums.
We could process a new simple report: the top 100 (or 500) IP adresses with: number of actions, bounce rate, etc.
This would help find bots, automated requests, or discover bugs in the tracking or other things.
I propose a new report, available only to the Super User and Admin user, displayed in Visitors>Ip Adresses.
This proposal is important and useful in the statistic tools.
Today i search this report type for the diagnostic.
Just released a small plugin providing such an report: https://plugins.piwik.org/IPReports
