Abstract
In a load balancing system, user-configurable geographic prefixes are provided. IP address prefix allocations provided by the Internet Assigned Numbers Authority (IANA) and associated geographic locations are stored in a first, static database in a load balancing switch, along with other possible default geographic location settings. A second, non-static database stores user-configured geographic settings. In particular, the second database stores Internet Protocol (IP) address prefixes and user-specified geographic regions for those prefixes. The specified geographic region can be continent, country, state, city, or other user-defined region. The geographic settings in the second database can override the information in the first database. These geographic entries help determine the geographic location of a client and host IP addresses, and aid in directing the client to a host server that is geographically the closest to that client.
