File location

Both the Forward and the Reverse entries files are located at the following path:


Sample configuration

Here, once again, feel free to copy and use the following text adapting it to your LAB.

$TTL 86400
@   IN  SOA (
        1        ;Serial
        1H       ;Refresh
        1H       ;Retry
        1W       ;Expire
        3H        ;Minimum TTL

        IN  NS
21      IN  PTR
169     IN  PTR
196     IN  PTR

Using “vi” to create the Reverse entries file

You can use the text editor of your preference or even better, use the GUI provided by WinSCP to make things as easy as possible.

vi /var/named/
DNS BIND Reverse Entries configuration file
