Method of determining a physical locale from an IP address

摘要

A method of determining a physical locale from a node name is presented. The method includes the steps of obtaining a DNS name from a node on a network, parsing the name, and obtaining the name of the Network Service Provider (NSP) from the parsed name. Each NSP has a particular rule set associated therewith, and the appropriate rule set is executed. The rule set extracts the city name, which indicates the general area where the node is located.
