Install BIND to configure DNS server which resolves domain name or IP address. DNS uses 53/TCP,UDP.
|
|
[1] | Install BIND 9. |
root@dlp:~# apt -y install bind9 bind9utils dnsutils
|
[2] | Configure BIND 9. On this example, Configure BIND with Grobal IP address [172.16.0.80/29], Private IP address [10.0.0.0/24], Domain name [srv.world]. However, Please replace IP addresses and Domain Name to your own environment. ( Actually, [172.16.0.80/29] is for private IP address, though. ) |
