Clear the DNS cache on your windows machines and home router first perhaps. Block it, then reboot after clearing cache.

They may have even further consolidated these endpoints into something else. I went through this exercise last year after network debugging a family members game that was hanging, only to find Akamai was down in my area for the activity endpoint. It is a never-ending arms race of whack-a-mole.

Another thing you can do is clear cache on your windows machine and router, then reboot and watch DNS requests as you launch applications. If they merged activity into a common endpoint, you should still see the requests.
