BIND : Use View Statement2023/06/15 |
This is an example to use View Statement in [named.conf].
On this example, Configure both settings for Internal Network like here
and settings for External Network like here with View Statement in [named.conf].

|
[1] | This example uses internal network [10.0.0.0/24], external network [172.16.0.80/29], domain name [srv.world], Replace them for your own environment. ( Actually, [172.16.0.80/29] is for private IP addresses, though. ) |
