Which IP address does a load balancer offer for external connections to connect to web servers in a load-balanced group?

Load balancers offer a virtual IP address, or VIP, that routes traffic to servers in a pool based on the load-balancing scheme employed by that pool. The round-robin scheme is frequently used, but other methods that involve priority order and capacity monitoring or ratings are also popular. The load balancer's IP address is typically used for system administration, while the individual IP addresses of the clustered hosts are safeguarded by the load balancer to prevent traffic from being directed constantly to those hosts, which could create a point of failure or overload.
