You don’t even need to run your own DoH server to take advantage of this new feature there are plenty of public DoH servers and websites with pre-built configuration profiles. VPN is tricky to set up correctly, can be somewhat flakey while using cellular data, and negatively impacts both device battery life and connection speed. Previously, the only way around a cellular carrier’s hard-coded DNS settings was to use a VPN to tunnel your traffic - a massive hassle. You’re no longer stuck using whatever DNS server your cellular carrier maintains. With iOS 14 (and macOS Big Sur) now natively supporting DoH, you can now force your device to use a custom DNS server - even while you’re using cellular data. DNS over HTTPS (DoH) is a relatively new protocol for performing DNS queries over the HTTPS protocol.
