I already installed Elasticsearch 8.4.0 in ubuntu and I find in the elasticsearch.yml file that the  
HTTP.host: 0.0.0.0 and #transport.host: 0.0.0.0  
is that mean that I should put the network.host also 0.0.0.0 ??  
thanks.

`network.host` will over ride the other two, it should really be the only one you need to set.

For security reasons always use fixed IPs or FQDNs.
