Hi all,

We have a cluster with some nodes having 2 network.host declared:

```
  network.host: ["1.2.3.4", 10.11.12.13"]

```

Our question is quite simple: which one will be used by nodes and masters to communicate between themself ? 👍 🙄

bye,  
Xavier

It's messy. We do our best to resolve them all and prioritise them (site local before loopback before multicast etc) and then publish the highest priority.

If you care, then you should probably set `network.publish_host`.
