In this part, we'll see how to leverage a built-in filter called network_hosts to create a list of all IPs within a given network.
This helps overcome the need to have multiple IPs defined in the variables tab / file, ease of user management.
First, we source the network IP from the variables tab and store the network address within the in-template variable network like so
{% capture network %}{{ instance.rxLanNetwork }}/26{% endcapture %}
Next, we load the list of IPs in that subnet into the in-template variable ip_addresses
{%- assign ip_addresses = network | network_hosts %}
Now all the IPs available within that network are accessible as offsets from the base IP.
Meaning a network = 192.168.0.0/30 would make
ip_addresses[1] = 192.168.0.0
ip_addresses[2] = 192.168.0.1
ip_addresses[3] = 192.168.0.2
ip_addresses[4] = 192.168.0.3
