What is Virtual IP Address [VIP] ? SAP

About  Virtual IP
A virtual IP address (VIP) is an IP address assigned to multiple domain names or servers that share an IP address based on a single network interface card (NIC). VIPAs are allocated to virtual private servers, websites or any other application residing on a single server. The host server for these applications has a network IP address assigned by a network administrator, whereas the different server applications have VIPAs. VIPAs enhance network load balancing and redundancy.
