Blocking ip addresses on iOS.

Questions
1

Hi there,
My goal is to block ip addresses like “8.8.8.8” on my iOS device. I use a custom DNS profile, but WhatsApp always bypasses it. In the App Privacy Report, I always see WhatsApp calling the ip address “8.8.8.8” directly. Basically, WhatsApp bypasses the DNS profile. Is there a way to block ip addresses with a profile? Also, I don’t want to block the ip on a firewall in my network, because I also have mobile data and when I’m not at home, I want the ip being blocked as well.
