By default, {product-title} allows any node in the worker machine configuration pool to host the `ingressVIP` addresses. Because vSphere environments deploy worker nodes in separate subnets from the control plane nodes, configuring the `ingressVIP` addresses to run exclusively on the control plane nodes prevents issues from arising due to deploying worker nodes in separate subnets.
