Consider this scenario:You have an AG with two replicas, one primary, one for ReadOnly access. Your clients are bound to only have access to specific IP ranges.e.g. Server A has IP 10.1.1.1 Server B has 10.1.1.2, the VNN for the AG is set to 10.1.2.1, all in the same /23 subnet. The clients by firewall rules only allowed to access 10.1.2.x IP addresses.Now that scenario works perfect for standard access via the VNN, as you can specify any IP there that the cluster can bring online. Unfortunately you can't do the same for the ROR partner.The workaround currently is to assign each server a static 10.1.2.x IP address, which could pose several problems along the way.
