The controller hostname recorded by ara for the controller can be something like 1.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.ip6.arpa (on OS X?)

What is the issue ?

Using ara under Mac OS X, the hostname that python picks up on my machine is 1.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.ip6.arpa which isn't particularly useful when the hostname and hostname -f commands both return a proper hostname like laptop.example.org.

We rely on python's socket.getfqdn() and socket.gethostname() to retrieve the hostname: https://github.com/ansible-community/ara/blob/196e256589893745c9f732c84f8edb7662997846/ara/plugins/callback/ara_default.py#L829-L833

On OS X (at least on my machine, I'm an OS X noob), getfqdn returns the ipv6 arpa mentioned previously and gethostname returns the actual hostname.

What should be happening ?

There's settings that determine which format is used:

In this particular case, hostname would probably be a better default than fqdn. Is this generally true for all distros ?

Changing it could result in playbooks being associated to a "new" controller if the fqdn and hostname are not the same.

Happy to hear what you think.
