``` nix
{
  networking.useDHCP = false;
  networking.interfaces.eth0 = {
    ipv4.addresses = [{
      address = /*"00.00.000.00"*/;
      prefixLength = /*00*/;
    }];
  };
  networking.defaultGateway = /*"00.00.000.000"*/;
  networking.nameservers = [ /*"0.0.0.0" "0.0.0.0"*/ ];
  networking.firewall = {
    enable = true;
    allowedTCPPorts = [ /*00 00 000*/ ];
  };
}
```

That's gitignored `neru-networking.nix`
better not to share it carelessly right? hehehe
