#### Instalar DNS SERVER 
Añadir el parametro: 
root@localhost# vim /etc/syconfig/named 
OPTION="-4" 
root@localhost# yum grouplist 
root@localhost# yum -y install "Servidor de nombres DNS"
root@localhost# touch /etc/named.conf 
root@localhost# cat >> /etc/named.conf << 'EOF'

     allow-query{ localhost; lan; dmz; };

     recursion yes; 
     allow-recursion { localhost; dmz; }; 
     forwarders {
