This one creates a directory with the same name as the PS4 update so the system can't create the update file.  You only need to apply this once to have it continue working as long as you don't delete the created directory. The DNS blocking stops the domain from resolving, this means the system cannot find the update to download because the URL points to the wrong IP address.  While this also stops telemetry data and other data being sent to/from Sony it requires that you be running, or connected to, the DNS.  Although if the DNS you have set is down you just won't be able to access any domain name and will still be safe. Do both.
