Different BIND/DNS responses by IP/NETWORK/VLAN etc. (security!)


view "trusted" {
 match-clients { 192.168.0.0/24; }; // allowed network
  recursion yes;
  // allowed zone - or forwarded zone
  zone "example.com" {
   type master;
   file "example.com";
  };
 };


view "banned" {
 match-clients {"any"; }; // all other networks
 recursion no;
 // zone disabled or forwarded
 zone "example.com" {
   type master;
   file "example.com";
  };
 };
