To list the target host's name and it's IP address using facts

[Pandu jh]

I need to list the target host's name and IP address using set_fact. Below is my playbook, but it's giving error.

  hosts:  all

  tasks:

    - set_fact:

        data:  "{{ ansible_all_ipv4_addresses }}"

    - set_fact:

        ip: "{{ data.split(',')  }}"

    - name: Show the devices

      shell: echo {{ item }} >> /tmp/ips

      with_items: "{{  blockdevices  }}"

Desired o/p is 

 host1 : 172.168.1.21

 system2:  172.168.1.22

Anybody help me to fix this pls ? thanks in advance

Assuming each host has only one ip address.  how about this?

  # for linux

#  - name: display ansible_default_ipv4.address

#    debug:

#      var: ansible_default_ipv4.address

  # for windows

  - name: display ansible_ip_addresses

    debug:

      var: ansible_ip_addresses

  - name: ansible_hostname

    debug:

      var: ansible_hostname

Each host has multiple Ip's. And i need to list those Ip's.
