Get IP from inventory which defined FQDN only

In the inventory file, I define FQDN values only. To render template file (Jinja), do we have any solution, in Ansible, to get the IP addresses from these hosts?

Inventory file:

[example_instance]
example1.com
example2.com

>Solution :

You can use the dig lookup for that. But, mind that you also need the dnspython library installed on your controller for it to work.

So, given the two tasks:

- pip:
    name: dnspython
  delegate_to: localhost
  run_once: yes

- debug:
    msg: "{{ lookup('dig', inventory_hostname) }}"

This would give you two IPs in return, in your case:

ok: [example1.com] => 
  msg: 192.185.44.208
ok: [example2.com] => 
  msg: 34.102.136.180
