ZeroMQ manages failover automatically when socket is being connected to multiple hosts. Dynamic connections mode assumes to connect once per message so we connect only to a single host. However we cannot say for sure if this host is still alive. For failover reasons we can connect to a primary host and then add some more hosts as failover and let ZeroMQ to decide where it finally sends the message.
