Session Based Measure Not IP Based

Hello,
I have an issue. We are using Piwik for a bank’s intranet platforms. Bank’s headquarter is OK, every client have unique IP address and measurement is quite true. However, branches have a different system and they are using one IP per branch, so I can not measure actual visitor counts. I see each actions under same IP.

So, I think I need to measure session number, bot IP address.
Is it possible or is there any other way to measure actual visitor count?
Thanks in advance.

Hi,

Are doing log analysis or using the tracking script on your intranet pages ?

The most common approach is to use the tracking script which doesn´t rely on IP-addresses.
