Hosts with IP range

Question

I have hosts without stable hostnames, but with predefined IP ranges.
How can I set the IP range for Ansible inventory file?

I'm trying to setup something like this:

test.ini:

[database]
db ansible_ssh_host=1.1.1.[20:25] ansible_ssh_port=22
[lemp]
lemp ansible_ssh_host=1.1.1.[10:15] ansible_ssh_port=22

And now I get this error after running ansible-playbook -i test.ini:

fatal: [db] => SSH Error: ssh: Could not resolve hostname 1.1.1.[20:25]: Name or service not known

Answer 1

I found this working solution for my problem:

test.ini:

# I removed hostname section and ansible_ssh_host=
10.0.3.[20:25] ansible_ssh_port=22
