Abstract
A network system wherein it is possible to reduce the amount of load on the mobile node and the amount of traffic from the mobile node to the IPv4/IPv6 translator and it is possible for the IPv4/IPv6 translator to know the node's current position within the IPv6 network in which the mobile node is moving. The network system having an IPv4/IPv6 translator for bilaterally translating packets between IPv6 and IPv4 protocols, where the translator is equipped with an address table for storing home addresses and care-of addresses in pairs for each MIPv6 mobile node and the translator is made to behave as a correspondent node of the MIPv6 mobile node in question after the mobile node has moved out of the home link thereof.
