Variables in named.conf

  • 772

My server have one IP and several domains hosted.

One and same IP appear in named.conf and several zone files.

When the IP address of the server changes, I need manually to change all those IP's.

Is there a way to do something like:

in named.conf:

#define $IP 123.123.123.123

zone file:

        MX 10     mail
        A         $IP
www     A         $IP
mail    A         $IP
*       CNAME     www

any help will be appretiated

  1. Well, if the IP Address is always the same for @, www and mail, you can add an $INCLUDE directive to your zone files (see here).

    Ideally, create a commons.db zone file with your common zone descriptions:

    @        IN    A    1.2.3.4
wwww     IN    A    1.2.3.4
mail     IN    A    1.2.3.4
*        IN    CNAME    www

    and then in your domain zone files simply do:

    @        IN    MX 10    mail
$INCLUDE  commons.db
