I am trying to block all connections to microsoft ip addresses. I only occasionaly boot windows and don’t want it phoning home. I tried disabling the net interfaces in device manager but windows just re-enables them and send god only knows what back to their servers. I don’t like relying on disconnecting the ethernet cable each time I boot windows because I forget to.
I found this list on their site. I didn’t verify if the ips match though.
Another way to solve this problem might be to block your MAC address at a router level (then unblock while booting).
Thanks for the list. I will try the mac address block on the router idea for windows and set a non default mac address when linux boots.
Windows will eventually retry those calls once it has internet.
