The Million Plus Resolver Challenge - Instructions

Bind 9.x Authoritative

For BIND 9.x authoritative servers, apply the following global options:

  options {
      recursion no;
      additional-from-cache no;
  };

Bind 9.x Caching

For BIND 9.x caching servers, additionally create access control lists and use "views" to explicitly permit a limited set of source addresses from your trusted network issue queries to your caching server:

  # example only, replace 192.0.2.0/24 a list of your CIDR blocks
  acl "trusted" {
      192.0.2.0/24;
  };

  options {
      recursion no;
      additional-from-cache no;
      allow-query { none; };
  };

  view "trusted" in {
      match-clients { trusted; };
      allow-query { trusted; };
      recursion yes;
      additional-from-cache yes;
  };
