description Examples described herein include a method and system for determining a number of controllers in a Network Authentication Server (NAS) controller cluster, wherein each of the controllers in the NAS controller cluster includes a unique Physical Internet Protocol (PIP) address; creating a number of unique Virtual Internet Protocol (VIP) addresses for use by an external authentication server (EAS) to communicate with the controllers in the NAS controller cluster, wherein the number of VIP addresses is to be proportional to the number of PIP addresses; and mapping each controller in the NAS controller cluster to a plurality of VIP addresses, wherein the VIP addresses are to have different priorities for different controllers in the NAS controller cluster.
