Internal VPN IPs run out - What happens?

NethServer Version: 8.x

NS8 allows multiple nodes. These nodes can be copied, or moved around. All worker nodes use an identified WG-VPN connection to the master node. An IP used is NEVER reused.

Assuming a Cluster with 10 Nodes. During a year, each node will be moved / cloned / whatever.
At the end of the year 100 IPs of the VPN network are used up, even though only 10 nodes are running.

After 2 - 2.5 years IPs in the VPN network run out. What happens?

A nice colorful code barf on the GUI?
A dead cluster?
A working cluster, but no cloning, moving or such possible.
Does the whole cluster need to be recreated?
Node per Node Backup?

For planing purposes, it would be good to know what options exist.

My 2 cents
