Virtual IP Address (VIPA)
Definition - What does Virtual IP Address (VIPA) mean?
A virtual IP address (VIPA) 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.
Techopedia explains Virtual IP Address (VIPA)
- To consolidate resources through the allocation of one network interface per hosted application
- To improve redundancy by providing alternative failover options on one machine
Several different application instances may be hosted with different VIPAs on the same server and easily switched for improved load balancing/performance and reduced latency.
VIPAs have several variations and implementation scenarios, including Common Address Redundancy Protocol (CARP) and Proxy Address Resolution Protocol (Proxy ARP).
