How to connect analytics or metrics without being tied to a specific domain?

Question

Google Analytics

There is a task to hang a metric or analytics on a site whose IP is referenced by a large number of domains. We wanted to analyze the behavior of visitors and distinguish data by domain. But metrics and analytics require setting a specific URL, what should I do?

Answer 1

Set the Metrica, in the counter settings you can list the list of domains from which to collect data. Place this counter on all domains. IP has nothing to do with it.

Answer 2

By default, GA eats any domains
Yes, and Metrica too - there is a checkmark in the settings like "limit data only to this domain"
In general, do not worry and set it as it is.
