Code review comment for lp:~niedbalski/charms/trusty/rabbitmq-server/hosts-ipv4

It's not a unrealistic expectation that IP address resolution should be functional within a MAAS managed environment; I'm reticent to put in a workaround in the charm as this feels like we're fixing the problem in the wrong place, and this will not just be a problem with the rabbitmq-server charm.
