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?

    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.

        Ok, I did test it.

        1. I set up DNS server on my PC using Technitium.
        2. I add zone a.local and add record with device A’s IP.
        3. I add zone b.local and add record with device B’s IP.
        4. On device A (Android 11) I go to Setting » WiFi and set DNS to PC’s IP.
        5. On device B (Android 13) I go to Settings » WiFi and:
          • Change IP to static
          • Change both DNS1 and DNS2 to PC’s IP.
        6. I ran some file served over http on both devices.
        7. I visit http://a.local/ on device B ❯ A’s Files accessed
        8. I visit http://b.local/ on device A ❯ B’s Files accessed

        Everything works.

        Note:

        • it took DNS server about 1min to add the records (idk why).
        • It seems devices caches NAME_NOT_RELOVED so if it failed it will be cached as such for at least a few minutes.
