Use a dynamic inventory script if you don't know the IP. That is what it is designed for. If you want to pass ssh usernames and passwords (extremely extremely insecure, please use SSH Keys), you can do that with ansible_ssh_user and ansible_ssh_pass inventory variables. You will need to have sshpass installed for this to work.
