If you want to track traffic from specific IP addresses, for example for corporate clients which are having access based on an IP address exclusion in a Composer Experience, you can use a Non-site action card in your Experience for that.
For this, you can create a separate monitoring Experience just for tracking those users, that would target an audience coming from a certain IP address and triggers a Non-site action card.
Then, the traffic can be tracked in the Flow report, where you will be able to see the number of executions on your site from customers coming from the specified IP address/es.
