METHOD AND APPARATUS FOR INTERNET PROTOCOL ADDRESS CONFIGURATION

摘要

An IP(Internet Protocol) address setup method and a device are provided to prevent unnecessary delay from occurring owing to an attempt of an address setup method which is not supported in a new network, thereby executing fast and efficient address setup. Information on an IP address setup method of a new network after handover is obtained through an IS(Information Server)(S100). IP address setup is performed by using the IP address setup method while a mobile node accesses the new network(S110). The information on the IP address setup method of the new network includes information indicating that the IP address setup method used in the new network is one of IPv6(IP version 6) stateless address configuration, IPv6 stateful address configuration, IPv4 static configuration, IPv4 dynamic configuration, and IPv6 manual configuration.
