How to track Unique Visitors based on the Visitor ID cookie, instead of using IP Address?
Piwik PRO by default will track a Unique Visitor based on the Visitor ID cookie (if visitor supports cookies) and/or matches the user fingerprint collected from the IP address and user device information (in cases when a visitor does not support cookies).
There are some situations when tracking Unique Visitors on the VIsitor ID cookie does not work as expected (for instance when you use Piwik PRO on an Intranet and all visitors have the same IP address)

Of course, it will be up to you to pass the correct value in the ‘USER_ID_HERE’ place.
