Correction, in OSP9, this is in tht directly, there is no rabbitmq logic in puppet-tripleo.

This likely only happens on pure-IPv6 deployments.  I have an IPv6-enabled OSP9 deployment but it also has IPv4 addresses configured.  

Because OSP9 does not contain the fixes for:

https://bugs.launchpad.net/tripleo/+bug/1645898

This causes epmd to listen on all interfaces.  The erlang resolver returns an IPv4 address for epmd connections, and because epmd is listening on IPv4 it all works, somewhat by accident.
