I know you already proceeded, but FWIW I think the complication with IP addresses are limited to changing the address of a node. It sounded like you were going to add 4 nodes and them simply decommission the rest. I don't think there's an issue with that having to do with IP addresses (someone correct me if I'm wrong). -- / Peter Schuller
