I’d look into something like ddns getting your dhcp server to update dns for you Then you can use the machine hostname?

But these addresses are not fixed, so can't I create the list of hosts by naming them with their MacAdress? I'm an Ansible beginner myself and there might be a better way but an idea is to address all machines and then use conditionals to assign tasks to MAC addresses https://docs.ansible.com/ansible/latest/user_guide/playbooks_conditionals.html https://stackoverflow.com/questions/40224460/getting-mac-address-from-ansible-facts-in-role - Ansible seems to be designed for connection to servers, machines that are constantly on. But the classrooms computers are often in standby, when they are not used. I have tried some direct SSH connection and it seems that this cannot be done if the target computer is in standby. Is Ansible also facing this obstacle? There are ways to run Ansible in a pull way like https://docs.ansible.com/ansible/latest/cli/ansible-pull.html (there might be others) You can use Wake-on-LAN to wake the machines up to be able to manage them https://docs.ansible.com/ansible/latest/modules/wakeonlan_module.html (and shut them down again when done) Thank you in advance for your help :) Seb -- You received this message because you are subscribed to the Google Groups "Ansible Project" group.
