About

I found it a pain to maintain multiple views in bind because I had to constantly modify two files (internal and external views).

Once I started using IPv6 I had another grief, I had to update IPv4 and IPv6 and CNAME records in two files.

This script reads from a metazone file and generates internal/external zone files. You can then use bind's acl and view features to craft what internal and external hosts see.

Running

There are a few dependencies

• perl with Parse::RecDescent

You may want to run this on Debian:

apt-get install libparse-recdescent-perl

There is a simple.metazone file that comes with the tool. Run it like so:

    zonegen --selector int simple.metazone
    cat example.com.int.zone

    zonegen --selector ext simple.metazone
    cat example.com.ext.zone

Example

For example, given

    foo: int=10.0.0.1 ext=72.0.0.1 2001:1234::1
    www: foo

You'll get this in the internal zone:

    foo.ipv6             IN AAAA    2001:1234::1
    foo.ipv4             IN A       10.0.0.1
    foo                  CNAME      foo.ipv6
    foo                  CNAME      foo.ipv4
    www                  CNAME      baz

and the external zone will contain:

    foo.ipv6             IN AAAA    2001:1234::1
    foo.ipv4             IN A       72.0.0.1
    foo                  CNAME      foo.ipv6
    foo                  CNAME      foo.ipv4
    www                  CNAME      foo
