Why are we creating so many duplicates of the same issue? We already identified in the initial BZ https://bugzilla.redhat.com/show_bug.cgi?id=2233300 that this was an issue with the Ansible core module for iptables. The problem can be avoided by using a valid DNS server. If you want the core Ansible module for iptables changed, then we need to pursue that via an Ansible issue. Takashi has already suggested the path forward in this comment: https://bugzilla.redhat.com/show_bug.cgi?id=2233300#c20 *** This bug has been marked as a duplicate of bug 2233300 ***
