Having the search domains and nameservers in resolv.conf in an optimal order should also help in this case.

Sounds like you have sketchy DNS then?

Might want to look into that...

    Just to short hostnames.

    *Prior to FQDN:*

    host1
    host2
    host3

    (resolv.conf had the search domains) - regular SSHing into
    machines worked, but ansible was either slow or never returned a
    value on “-m ping”.

    *After adding FQDN:*

    host1.domain.com <http://host1.domain.com>
    host2.domain.com <http://host2.domain.com>
    host3.domain.com <http://host3.domain.com>

    (resolv.conf still has the search domains, but aren’t needed for
    Ansible now because I’m using the FQDN) - huge performance
    increase and no more failures.

    What was in the hosts file prior to the FQDNs ?

    So, it appears that I’ve figured it out - but don’t really
    understand why exactly.  As you can see from my previous threads
    that I was able to SSH into the host, but Ansible just wouldn’t
    return anything for a random host, correct?  Another thing I
    noticed was it was also a bit slow.  In our environment, we have
    about 4 main domains, for different locations.  In the
    /etc/resolv.conf file, we have search domains defined so we can
    use the short hostnames that are in DNS.  This doesn’t appear to
    have any issues whatsoever, except sometimes in Ansible; not
    sure why.

    What I ended up doing was adding the FQDN into the
    /etc/ansible/hosts file to each host, and when I did that I got
    a HUGE performance increase and I also no longer run into this
    problem.
