When a system is deployed with Fold/Unfold enabled, three extra IP addresses are provisioned and assigned on each node. These IP addresses are redistributed during folding and unfolding. No new COP IP addresses are allocated for unfolding and no COP IP addresses are removed for folding. Due to this, client machines can use the same group of COP entries to connect to the folded or unfolded system. In other words, folding and unfolding are transparent on client machines that have COP entries properly configured.
