rDNS

My own crafting for an rDNS generation for my own local IPv4 and IPv6 ranges. The numbering format is simply the standard shortest form replacing any : or . with -

Using

Example

2001:db8::/32 ipv6.example.com {
    rdns {
        prefix "ip"
        suffix ".ipv6.example.com"
    }
}

192.168.0.0/24 ipv4.example.com {
    rdns {
        prefix "ip"
        suffix ".ipv4.example.com"
    }
}

Or you can even combine all of them together

2001:db8::/32 ipv6.example.com 192.168.0.0/24 ipv4.example.com {
    rdns {
        v6-prefix "ip"
        v6-suffix ".ipv6.example.com"
        v4-prefix "ip"
        v4-suffix ".ipv4.example.com"
    }
}

Options

suffix: This sets both v6-suffix and v4-suffix to the specified value. vN-suffix: This sets the suffix for the specified IP version, so that you can have individual suffixes

prefix: Like suffix though allowing you to set the prefix vN-prefix: the same as vN-suffix but as the prefix

Please note: the leading dot is REQUIRED

ttl: set the TTL (default 86400)
