Ansible hostname and IP address - variables

Question

How I can use the value of hostname and IP address from hosts inventory file?
For example, I have only one host in the hosts file with name as FQDN, but this is registered on the DNS server.
I tried with some vars, but always get the hostname. But, need both of them :(
Output of request to DNS server:
nslookup host1.dinamarca.com
Server: 10.10.1.1
Address: 10.10.1.1#53
Name: host1.dinamarca.com
Address: 192.168.1.10
Example host file: (only have one host)
host1.dinamarca.com
I call the service ansible with the command:
ansible-playbook --ask-pass -i hosts test.yml
My test.yml file:
---
- name: test1
hosts: host1.dinamarca.com
remote_user: usertest
tasks:
- name: show ansible_ssh_host
debug:
msg: "{{ ansible_ssh_host }}"
- name: show inventary_hostname
debug: var=inventory_hostname
- name: show ansible_hostname
debug: var=ansible_hostname
...
Output is:
TASK [show ansible_ssh_host] ****************************************************************************************************************************************
ok: [host1.dinamarca.com] => {
"msg": "host1.dinamarca.com"
}
TASK [show inventary_hostname] **************************************************************************************************************************************
ok: [host1.dinamarca.com] => {
"inventory_hostname": "host1.dinamarca.com"
}
TASK [show ansible_hostname] ****************************************************************************************************************************************
ok: [host1.dinamarca.com] => {
"ansible_hostname": "host1"
}
PLAY RECAP ************************************************************************************************ *************************************************************
host1.dinamarca.com : ok=4 changed=0 unreachable=0 failed=0 skipped=0 rescued=0 ignored=0

There is an Ansible fact called ansible_fqdn. If you need both the hostname and FQDN, you can have tasks like this:
tasks:
- name: show ansible_ssh_host
debug:
msg: "{{ ansible_ssh_host }}"
- name: show inventory_hostname
debug:
msg: "{{ inventory_hostname }}"
- name: show ansible_hostname
debug:
msg: "{{ ansible_fqdn }}"
