Set Zones for Name Resolution
2014/08/02
 
Create zone files that servers resolve IP address from domain name.
[1] For internal zone
This example uses internal address[10.0.0.0/24], domain name [srv.world], but please use your own one when you set config on your server.
[root@dlp ~]#
vi /var/named/srv.world.lan 
$TTL 86400
@   IN  SOA     dlp.srv.world. root.srv.world. (
        2014080201  ;Serial
        3600        ;Refresh
        1800        ;Retry
        604800      ;Expire
        86400       ;Minimum TTL
)
# define name serve

        IN  NS      dlp.srv.world.
# internal IP address of name server

        IN  A       10.0.0.30
# define Mail exchanger

        IN  MX 10   dlp.srv.world.
# define IP address and hostname

dlp     IN  A       10.0.0.30
[2] For external zone
This example uses external address [172.16.0.80/29], domain name[srv.world], but please use your own one when you set config on your server.
[root@dlp ~]#
vi /var/named/srv.world.wan 
$TTL 86400
@   IN  SOA     dlp.srv.world. root.srv.world. (
        2014080201  ;Serial
        3600        ;Refresh
        1800        ;Retry
        604800      ;Expire
        86400       ;Minimum TTL
)
# define name server

        IN  NS      dlp.srv.world.
# external IP address of name server

        IN  A       172.16.0.82
# define Mail exchanger

        IN  MX 10   dlp.srv.world.
# define IP address and hostname

dlp     IN  A       172.16.0.82
