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?

    Not sure about e/OS but generally on android you can set DNS when connecting to Wifi.
    So you should be able to change that in Settings » WIFI » [Your local network] » DNS

      Did you ever tested it? Because in any android device I got, it always “default” to 8.8.8.8 - google’s one. I have to connect to a vpn do get local ips being resolved. I just don’t get it, is this normal?

        I don’t have a custom DNS server configured, but that’s what I tested:

        • Went to Settings » Connections and Share » Private DNS - made sure it is off (it takes priority when set)
        • Went to Settings » WiFi » [My local network] » DNS1 and entered my router’s IP

        After that it started to use my ISP’s DNS servers (preconfigured in router) instead of CloudFlare 1.1.1.1 (what was default on my android when connecting to WiFi

          Yes but how do you know that is using that? I mean, did you try to resolv a local address? I have test it using a Terminal (termux) - If I use did and seems to report all the time, regardless of which connection and despite setting my local DNS setting on a static configuration for the wifi. Is this the same for you? can you share some screenshot?

            I visited http://ipleak.net/ to check which dns is used.
            In Termux nslookup will use 8.8.8.8, but I suspect it takes it from Termux environment that doesn’t sync with android settings.

              Are you sure? I believe that using ipleak.net will provide you with a detailed report of your public IP address, DNS servers, WebRTC status, and other network-related information. However, it will not show you the internal DNS server you are using within your local network.

              You are right that Android’s system-wide DNS settings (e.g., those configured in Wi-Fi or mobile network settings) are not automatically applied to Termux. Termux runs in a sandboxed environment and manages its own network configuration. I will try changing Termux but keep in mind that the reason I checked Termus is because local dns resolution do not work on all my android devices, I can resolv local addresses only if I connect to my home network remotely using a vpn.

                I believe that using ipleak.net […] will not show you the internal DNS server you are using within your local network.

                You’re right. It won’t show internal one. As I mentioned I don’t have internal DNS server set up, so I only used it to check whether changing DNS in wifi settings will actually take effect, and it did. That’s why I believe setting it to internal one should take effect as well.

                I may try to setup custom DNS in my local network when I have some free time.
