Install/Configure BIND
2014/04/19 |
Configure DNS server which resolves domain name or IP address. BIND uses 53/TCP,UDP.
|
|
[1] | Install BIND 9 |
root@dlp:~# apt-get -y install bind9 bind9utils
|
[2] | Configure BIND. This example is set with grobal IP address [172.16.0.80/29], Private IP address [10.0.0.0/24], Domain name [srv.world]. However, Please use your own IPs and domain name when you set config on your server. ( Actually, [172.16.0.80/29] is for private IP address, though. ) |

For 10.0.0.0/24 network address ⇒ 10.0.0.0 network range ⇒ 10.0.0.0 - 10.0.0.255
how to write
For 172.16.0.80/29⇒ 0.0.10.in-addr.arpa
