unreachable host comes in failed task

[Azadeh Amirhosseini]

Hi All,
I am usning ansible-core 2.16.7

when there exists an unreachable host in the hostname list by inventory, say the ip-address is wrong, in the output of the playbook, it comes under failed task, but i expect it to come on unreachable host, as later in call-back module i will do some process on it.

Anyone has any idea about it, please?
