Note that it is still good to disable bind on listening on IPv6 addresses by commenting
<pre>
//listen-on-v6 port 53 { ::1; };

Disabling IPv6 lookups in bind

Just disabling bind to listen on IPv6 addresses does not prevents it from querying for IPv6 addresses to remote hosts. To ensure that IPv6 is completely disabled use:

  1. Edit /etc/sysconfig/named and set 
    OPTIONS="-4"
  2. Edit '/etc/named.conf' and set 
    filter-aaaa-on-v4 yes;
    Also optionally comment 'listen-on-v6 port 53 { ::1; };'
  3. Finally use 'service named restart'
