    Is there a way to apply DNS settings system wide and not only for a specific network?

      The only thing you could do is apply this DNS settings to the modem/router in order to force every connected device to use the CloudFlare service, so you don’t have to set up every single device as well.

    Yes my question as well, on my MacBook Pro it seems to retain the manual settings when I change routers, but not on my iPhone.
    Also what happens on mobile networks?

      I am having the same problem. The changes work on my iMac but not on my iPhone.

        Use a VPN. Select the same DNS server.
        Then everytime you use the VPN, the DNS server is set for you.

    Some of us have routers supplied by an ISP; and some of these routers have DNS numbers baked in.

    This is the case with my current Xfinity router (yea, I’ve checked; cannot change the DNS numbers).

    So, the question is: if I set up these Cloudflare numbers on my Mac, how do I know that the router isn’t using its own DNS addresses, and not the Cloudflare ones I specify on my mac?

    Go to the config page of your router, DHCP, DHCP settings, then change the DNS numbers to whatever you want. Click save, depending on the router it may require a reboot. Personally I would not switch to this until more is known. OpenDNS is doing quite well at the moment for me

      As I said, some of these routers have unchangeable DNS addresses; they point to the ISP servers (Xfinity in this case).
