CONFIGURABLE GEOGRAPHIC PREFIXES FOR GLOBAL SERVER LOAD BALANCING
First Claim
1. An apparatus, comprising:
- a network device configurable to, for a network address that has a particular address prefix that matches a stored address prefix corresponding to a geographic region, associate said network address to said geographic region, said geographic region being different from an original geographic region that corresponds to the particular address prefix.

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.
