This is not working? Is there a better way to do this? Or please suggest a fix.

Consider using the dig-lookup: https://docs.ansible.com/ansible/playbooks_lookups.html#the-dns-lookup-dig

Your tasks: is misplaced and indentation is wrong, but this should work

- name: Set DNS variable
   command: dig {{ ansible_fqdn }} +short
   register: DNSOUT

- name: Verify DNS
   command: echo not in DNS!
   when: DNSOUT.stdout == ""

The Verify DNS task won't show you anything on in the console, if that's what you are after you can do it like this

- debug: msg="{{ ansible_fqdn }} not in DNS!"
   when: DNSOUT.stdout == ""
