(nethserver) How to add a domain to white List

[zsconsulting]

First of all my apologies if you find the question silly but I am very "green" in these things. :)

I am using nethserver 7 and i noticed that the domain analytics.google.com is in the list.
As I need access to this domain, I would like to know how to add it to the whitelist / exception list.

Thank you in advance for your patience and support.
