Hello,

After struggling for hours why Filebeat can't connect to ES, I realised that this setting in elasticsearch.yaml is the culprit. It is only listening to IPv4 and not IPv6.

> network.host: 0.0.0.0

I tried many different ways to add ::/0 to it, but I can't restart ES successfully.  
What is the right format to listen to 0.0.0.0 and ::/0 please?

Thanks,

Just use `_site_` and it will bind to all available interfaces.

Thanks for your reply.

I'm sorry I'm not following. According to this [page](https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-network.html#network-interface-values), site is for site-local addresses.

**`_site_`**  
Any site-local addresses on the system, for example 192.168.0.1 .

I would like to bind to both IPv4 and IPv6. I don't think this is the right solution. Or do you mean I should use `network.host: _site_` or something?
