I’m using e/os and I want to be sure that, when connected to my local network, my local dns server is used, however, no matter what I do, my phone always use google’s one. Is there any way to fix this?
I’m using e/os and I want to be sure that, when connected to my local network, my local dns server is used, however, no matter what I do, my phone always use google’s one. Is there any way to fix this?
how do we get phones to see local DNS records?
like every other devices I supposed…but it doesn’t work in any mobile I got. the dns server stay google’s one no matter what you do.
I had the same problem in my network and the solution is not easy.
Many, but many android apps are using Google dns servers just to leak the location of the phone (using the nearest geographical Google server).
The only way I found it was to instsll an opnsense router and redirect requests to port 53 to the internal dns server.
DoT (dns over tls) is blocked because it can not be redirected
DoH (dns over https) is (almost) imposible to block and still is a hole in current systems.
Good luck solving this
You can block DoH by using a comprehensive blocklist of DoH domains. Both NextDNS and ControlD do this.
