"listen-on-ipv6" only applies to incoming DNS traffic, but not the outgoing DNS traffic. It is a valid configuration to have a DNS resolver or authoritative DNS server to listen only on IPv4 but have it use IPv6 for queries towards other DNS servers.

The command
named-checkconf -p
prints the content of "named.conf" and all included files in canonical form. That for can be parsed.
