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 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.
