A Method of IPv4 communication in IPv6 Wireless LAN

摘要

PURPOSE: An IPv4 communication method under IPv6 wireless LAN environment is provided to give all services by using an IPv6 address, and to dynamically receive a public IPv4 address if an IPv4 terminal is communicated, thereby carrying out communication with the IPv4 terminal. CONSTITUTION: An initial IPv6 terminal prepares for a process(210). The initial IPv6 terminal interprets an IP for a domain name at the request of an application program(220). The initial IPv6 terminal decides whether a destination address for the requested domain name is a public IPv4 address(230). If so, the initial IPv6 terminal is dynamically assigned with the public IPv4 address for IPv4 communication(240). The initial IPv6 terminal returns the address when the public IPv4 address expires(250).
