The notes explain that diagnostic telemetry data is sent to settings-win.data.microsoft.com. Privacy advocates note that this is hard-coded, so blocking access via the hosts doesn't work.
So what does that mean? Are they saying the IP Address is hard coded? Usually I block this kind of stuff in the DNS not the hosts file. I'm assuming that they are not doing a lookup and going direct to the IP Address. If that is the case, why don't these articles list the relevant IP Addresses to be blocked by a firewall?
