How can I set a custom DNS server within Nixos?

Question

I've not found much information in the manual.

I've tried to manually modify the file /etc/resolv.conf however this seems to be overwritten by something?

How can I achieve this?

What file path should this line be added to?

@JayWhitsitt Everything in NixOS should be configured via /etc/nixos/configuration.nix (unless you use flakes), so you should add it there. See nixos.org/manual/nixos/stable/index.html#sec-changing-config and nixos.org/manual/nixos/stable/index.html#ch-configuration for more info.

  environment.etc = {
    "resolv.conf".text = "nameserver 192.168.0.32\n";
  };

Adding the above to my /etc/nixos/configuration.nix seems to work.
