No network connection when using mobile data

[DCsunset]

Hi,

When the phone is connected to WiFi, commands running in nix-on-droid have access to Internet.
But if I switch to mobile data, no Internet connection can be made (i.e. cannot connect to any IP address), while Termux still has Internet access.

Only special network thing in here is DNS, so, check that your mobile operator doesn't block nix-on-droid default DNS.

Thanks for the pointer. After further investigation, I found that it's indeed the DNS issue, which is mentioned in #2.
My case might be a bit different because it seems that my mobile operator only supports IPv6. That's why the hard-coded 1.1.1.1 and 8.8.8.8 fail to work.

If it's hard to get the the upstream DNS directly, is it okay to at least add an IPv6 DNS resolver to resolv.conf? It would help the people who have access to IPv6 only.

Or I think a better way is to expose the DNS config so the user can overwrite it.
