my inventory

testhost ansible_host=192.168.3.4

how to get this ip when running ansible

Here the dictionary hostvars and the variable inventory_hostname help us. hostvars includes every variable from wherever it comes and the
inventory_hostname contains the hostname of the current host itself. So with hostvars[inventory_hostname] I can access a dictionary with all Properties of the current host.

Here are the keys:

ansible -m debug testhost -a 'msg={{ hostvars[inventory_hostname].keys() }}'
testhost | SUCCESS => {
    "msg": [
        "ansible_password",
        "ansible_become_pass",
        "searchDomain",
        "ansible_user",
        "ansible_ssh_common_args",
        "inventory_file",
        "inventory_dir",
        "ansible_host",
        "inventory_hostname",
        "inventory_hostname_short",
        "group_names",
        "ansible_facts",
        "playbook_dir",
        "ansible_playbook_python",
        "ansible_config_file",
        "groups",
        "omit",
        "ansible_version",
        "ansible_check_mode",
        "ansible_diff_mode",
        "ansible_forks",
        "ansible_inventory_sources",
        "ansible_verbosity"
    ]
}
ansible testhost -m debug -a var=ansible_host
# and now get the IP-Address:
testhost | SUCCESS => {
    "ansible_host": "192.168.3.4"
}

other important variables are:

HOME
