hostvars['somehost']['ansible_default_ipv4'].address
inventory_hostname is a var worth mentioning: it's the hostname of the local
system. useful for:
hostvars[inventory_hostname]['ansible_default_ipv4']
there's also a 'groups' top-level var you can use to iterate through the
inventory, which may or may not be
better than iterating through hostvars to get your list of hosts. pardon, been
a couple months since i touched
that particular use-case.
