Expanding Elasticsearch cluster but IP is the same as Kibana

Hi,

Problem: I want to expand my cluster to have 3 nodes (1 master, 2 data), however, in my current config, the elasticsearch node + kibana instance have the same IP.

I wish to use the current IP for kibana and spin up new VMs for the elasticsearch nodes. I'm not sure how to go about doing this, so I was hoping to get some guidance.
