I no longer blindly trust the numerous connections that occur at night and during the day that always go to "content" and "push" servers like:
a23-33-37-54.deploy.akamaitechnologies.com st11p01st-courier001-bz.push.apple.com ve-in-f113.1e100.net
These always happen at night when no one is using the computer. I do not have iCloud enabled.
So I would like to block these. Is there an effective way to do that?
I tried setting these as keywords to block in my wifi router that that doesn't seem to work, perhaps because these sites are not being accessed by a browser.
However this will not block direct access to an IP address e.g. https get from 18.104.22.168:443.
How can I block an IP range?
Thanks for any clues.
