- debug: msg="Reverse DNS for 192.0.2.5 is {{ lookup('dig', '5.2.0.192.in-addr.arpa.', 'qtype=PTR') }}"
By default, the lookup will rely on system-wide configured DNS servers for
performing the query. It is also possible to explicitly specify DNS servers to
query using the ``@DNS_SERVER_1,DNS_SERVER_2,...,DNS_SERVER_N`` notation. This
needs to be passed-in as an additional parameter to the lookup. For example::
- debug: msg="Querying 8.8.8.8 for IPv4 address for example.com. produces {{ lookup('dig', 'example.com', '@8.8.8.8') }}"
- debug: msg="Querying 198.51.100.23 for IPv4 address for example.com. produces {{ lookup('dig', 'example.com', '@198.51.100.23') }}"
In some cases the DNS records may hold a more complex data structure, or it may
be useful to obtain the results in a form of a dictionary for future
