NextDNS

NextDNS is a commercial DNS provider with a subscription model. The DNS resolution is highly configurable

Installation and configuration

It is necessary to install the nextdns package in addition to enabling the service. Otherwise it is not possible to (de-)activate it.

To install NextDNS its necessary to enable the service and supply the link to the subdomain of the configuration (abcdef will use abcdef.dns.nextdns.io). The cache-size is optional. Default for cache-size is not using a cache at all.

services.nextdns = {

 enable = true;
 arguments = [ "-config" "abcdef" "-cache-size" "10MB" ];

};

Activation

NextDNS needs to be activated after a NixOS rebuild. It can be activated manually or by configuration.

Manual activation

sudo nextdns activate

Activation by configuration

systemd.services.nextdns-activate = {
    script = ''
      /run/current-system/sw/bin/nextdns activate
    '';
    after = [ "nextdns.service" ];
    wantedBy = [ "multi-user.target" ];
  };
