$ ansible-doc add_host

	> ADD_HOST    (/usr/lib/python2.7/site-packages/ansible/modules/inventory/add_host.py)

	  Use variables to create new hosts and groups in inventory for use in later plays
	  of the same playbook. Takes variables so you can define the new hosts more fully.

	  * note: This module has a corresponding action plugin.

	Options (= is mandatory):

	- groups
	        The groups to add the hostname to, comma separated.
	        [Default: (null)]
	= name
	        The hostname/ip of the host to add to the inventory, can include a colon
	        and a port number.
	Notes:
	  * This module bypasses the play host loop and only runs once for all the
	        hosts in the play, if you need it to iterate use a with\_ directive.
	EXAMPLES:
	# add host to group 'just_created' with variable foo=42
	- add_host:
	    name: "{{ ip_from_ec2 }}"
	    groups: just_created
	    foo: 42

	# add a host with a non-standard port local to your machines
	- add_host:
	    name: "{{ new_ip }}:{{ new_port }}"

	# add a host alias that we reach through a tunnel (Ansible <= 1.9)				
	- add_host:
	    hostname: "{{ new_ip }}"
	    ansible_ssh_host: "{{ inventory_hostname }}"
	    ansible_ssh_port: "{{ new_port }}"

	# add a host alias that we reach through a tunnel (Ansible >= 2.0)
	- add_host:
	    hostname: "{{ new_ip }}"
	    ansible_host: "{{ inventory_hostname }}"
	    ansible_port: "{{ new_port }}"
