Blocky

Blocky is a DNS proxy and ad-blocker for the local network written in Go. It provides network wide adblocking similar to Pi-hole while offering additional features (and it's in nixpkgs).

Configuration Examples

services.blocky = {

   enable = true;
   settings = {
     port = 53; # Port for incoming DNS Queries.
     upstream.default = [
       "https://one.one.one.one/dns-query" # Using Cloudflare's DNS over HTTPS server for resolving queries.
     ];
     # For initially solving DoH/DoT Requests when no system Resolver is available.
     bootstrap.Dns = {
       upstream = "https://one.one.one.one/dns-query";
       ips = [ "1.1.1.1" "1.0.0.1" ];
     };
     #Enable Blocking of certian domains.
     blocking = {
       blackLists = {
         #Adblocking
         ads = ["https://raw.githubusercontent.com/StevenBlack/hosts/master/hosts"];
         #Another filter for blocking adult sites
         adult = ["https://blocklistproject.github.io/Lists/porn.txt"];
         #You can add additional categories
     };
     #Configure what block categories are used
     clientGroupsBlock = {
       default = [ "ads" ];
       kids-ipad = ["ads" "adult"];
     };
   };
 };

Adding Additional Functionality

To add a cache of DNS Requests and Prefetching add:

caching = {

 minTime = "5m";
 maxTime = "30m"
 prefetching = true;

};
