A method and system capable of providing mobility support for IPv4/IPv6 inter-networking to a mobile node is disclosed. The mobile node in the system has an address mapper, an IPv4 protocol stack and an IPv6 protocol stack in the network layer. When moving from IPv4 to IPv6 networks, the mobile node registered an IPv4 address receives router advertisement packets from an IPv6 router, so as to obtain a IPv6 care-of-address, and resolve the IPv6 care-of-address by an IPv4 care-of-address. The address mapper issues an IPv4 message to register the IPv4 care-of-address. When moving from IPv6 to IPv4 networks, the mobile node registered an IPv6 address receives agent advertisement messages from a foreign agent, so as to obtain an IPv4 care-of-address, resolve the IPv4 care-of-address by an IPv6 care-of-address. The address mapper issues an IPv6 message to register and update binding information by the IPv6 care-of-address.
