I'd like to find a way to block websites like https://checkip.amazonaws.com or at least restrict them to the point they can no longer output my server's public IP address.
For example, if I do curl https://checkip.amazonaws.com my output would simply be 1.1.1.1 (or in other words, my IP address).
Is there a way to have an app that would inspect the output of each website my server tries to connect to and if the output contains a specific string, it automatically blocks it?
Thanks!
