`dig` module through nested list

Hi all,

I have a data-structure like the below that consists of few internal hostnames.

client_groups:
apache-servers:

  • apa01-pco.web.vpn
  • apa02-pco.web.vpn
  • apa03-pco.web.vpn

mailout:

  • mo11-pco.mail.vpn
  • mo12-pco.mail.vpn
  • mo13-pco.mail.vpn

These are provided in as vars. I’m trying to write a task that uses dig plugin to produce dicts of their respective A records like the below:

client_groups:

apache-servers:

  • ‘10.5.10.111’
  • ‘10.2.10.112’
  • ‘10.5.10.11’

mailout:

  • ‘1.2.3.4’
  • ‘5.6.7.8’

So far, I’ve been able to write a task like the below:

pre_tasks:
- name: Setting log-client IPs
set_fact:
ip_addr: ‘{{ lookup(“dig”, item) }}’
with_flattened: ‘{{ client_groups }}’
register: dig_results

Please let me know what I am missing. Any hints would be helpful.
