OP is stating that "apps and devices" may circumvent DNS blocking by resorting to DoH. You can run your own DoH server, and you can even advertise it via your DHCP server, but clients ("apps and devices") do not need to accept the supplied servers for their own configuration.
- randomhodler84 4y agoA lot of things are possible, but are they done? I am yet to hear of any examples of hardcoded DNS servers. I believe this to be too fragile to implement.
- random1temp2 4y agoLeague of Legends hardcodes 8.8.8.8.
- randomhodler84 4y agoThank you for the example, probably 53/udp, which one can set up a NAT rule to direct all outgoing 53 to the local filtering DNS resolver.
- autoexec 4y agoThey don't even have to be hardcoded, they just have to ignore anything you specify or not give you any option to specify your own. As long as a device manufacturer can push updates to your device (even by IP address) they can regularly update their chosen DNS servers when needed. Honestly though, for many devices I doubt they'd even bother. Companies seem to have little trouble taking the position that if your device is more than a few years old you're insane for expecting them to still support it and you should have already thrown it away and bought another one.
