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:
Settings » Connections and Share » Private DNS- made sure it is off (it takes priority when set)Settings » WiFi » [My local network] » DNS1and entered my router's IPAfter 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
nslookupwill use 8.8.8.8, but I suspect it takes it from Termux environment that doesn't sync with android settings.
