How to determine all the resources used by the site?

Question

System administration

When you open any site, different content is additionally loaded - widgets from one IP, some counters from another, advertising banners from a third, etc. Is there a tool that can give a complete list of IPs and domains that are loaded along with the rest of the site by the domain (or IP) of the site? The question is related to the fact that it is required to give the computer access to a certain site (forbid the rest). The task is solved, but the required site is not always loaded / not all / stupid for a long time, because. uses some other external resources, they will also need to be resolved, the question is in determining this list of resources.
