# TASK [Check if 10.1.1.1 is a valid IPv4 address] *************************************
# ok: [localhost] => {
#     "ansible_facts": {
#         "data": true
#     },
#     "changed": false
# }

- name: Check if 10.1.1.1/31 is not a valid IPv4 address
  ansible.builtin.set_fact:
    data: "{{ '10.1.1.1/31' is not ansible.utils.ipv4_address }}"

# TASK [Check if 10.1.1.1/31 is a valid IPv4 address] **********************************
# ok: [localhost] => {
#     "ansible_facts": {
#         "data": true

Hint

Configuration entries for each entry type have a low to high priority order. For example, a variable that is lower in the list will override a variable that is higher up.
