IP pools group ranges of IP addresses. They can be designated as public and private IP addresses. You can allow using only certain IPs on the cluster nodes.
To add a range into the pool:
Go to Networks → IP pools → menu → Create a range or open the pool page → Create a range.
Specify the IP range of the pool. You can enter a single IP address ("1.1.1.1"), a mask ("1.1.1.1/24") or a range ("1.1.1.1-1.1.1.5").
To create a physical network that the range for the pool is allocated from:
Enable the option Create a physical network.
Enter a Network in the following format <network IP address>/<network mask prefix>. E.g. "172.0.0.0/24".
Enter a Gateway.
Click on Create.
Note
To add IP addresses for a cluster node with the "Routing" network configuration type, go to Nodes → host name → IP addresses → select IPv4 or IPv6 → Add an IP Address.
