Answer

The short answer to your specific question of listing CNAMEs is that you cannot without permission to do zone transfers (see How to list all CNAME records for a given domain?).

That said, if your company's DNS server still supports the ANY query, you can use dig to list the other records by doing:

dig +noall +answer +multiline yourdomain.yourtld any 

These ... +noall +answer +multiline ... are strictly optional and are simply output formatting flags to make the output more easily human readable (see dig man page ).

Example

$ dig +noall +answer +multiline bad.horse any

Returns:

bad.horse.              7200 IN A 162.252.205.157
bad.horse.              7200 IN CAA 0 issue "letsencrypt.org"
bad.horse.              7200 IN CAA 0 iodef "mailto:abuse@sandwich.net"
bad.horse.              7200 IN MX 10 mx.sandwich.net.
bad.horse.              7200 IN NS a.sn1.us.
bad.horse.              7200 IN NS b.sn1.us.
bad.horse.              7200 IN SOA a.sn1.us. n.sn1.us. (
                                2017032202 ; serial
                                1200       ; refresh (20 minutes)
                                180        ; retry (3 minutes)
                                1209600    ; expire (2 weeks)
                                60         ; minimum (1 minute)
                                )

Caveats (RFC8482)

Note that, since around 2019, most public DNS servers have stopped answering most DNS ANY queries usefully. For background on that, see: https://blog.cloudflare.com/rfc8482-saying-goodbye-to-any/

If ANY queries do not enumerate multiple records, the only option is to request each record type (e.g. A, CNAME, or MX) individually.

Try configuring zones for your blacklists, and configure them not to forward. Something like this should work. You will need one of these for each blacklist zone.

zone "blacklist.example.com" {
    type static-stub;
    recursion yes;
};

You will also need to setup the root zone so recursion will work. You likely already have done this.
