 ### Disabling public IPs (IPv4 or IPv6 or both) on nodes
 
-With `enable_public_net_ipv4: false` and `enable_public_net_ipv6: false` you can disable the public interface for all nodes for improved security. These settings are global and effects all master and worker nodes. If you disable public IPs be sure to run hetzer-k3s from a machine that has access to the same private network as the nodes either directly or via some VPN.
+With `enable_public_net_ipv4: false` and `enable_public_net_ipv6: false` you can disable the public interface for all nodes for improved security and saving on ipv4 addresses costs. These settings are global and effects all master and worker nodes. If you disable public IPs be sure to run hetzer-k3s from a machine that has access to the same private network as the nodes either directly or via some VPN.
 Additional networking setup is required via cloud init, so it's important that the machine from which you run hetzner-k3s have internet access and DNS configured correctly, otherwise the cluster creation process will get stuck after creating the nodes. See [this discussion](https://github.com/vitobotta/hetzner-k3s/discussions/252) for additional information and instructions.
