Disabling Recursive loopkups in Bind

If you own your DNS servers, you should probably want to close recursive queries being gathered from your servers.

In named.conf edit the options directive and add:

options {
allow-transfer {Secondary Server IP; }; allow-recursion {; A.B.C/24; };


In secondary server:
add to options:

allow-transfer { none; }; allow-recursion {; A.B.C/24; };
