Create zone files that servers resolve IP address from domain name on linux.

  Create zone files that servers resolve IP address from domain name on linux.

[1] For internal zone
This example uses internal address[192.168.0.0/24], domain name[server-linux.info], but please use your own one when you set config on your server.

604800;Expire
86400;Minimum TTL
)
# define name server

[2] For external zone

This example uses external address[172.16.0.80/29], domain name[server-linux.info], but please use your own one when you set config on your server.
