A method for optimizing dual-moved IPv4 node route in a pure IPv6 network is provided. The method comprises following steps: when dual-moved nodes are connected to the pure IPv6 network, accessed IPv6 addresses are received by a first router; a local agent is updated by the accessed IPv6 addresses; binding update with communication nodes by the local agent is logged-out; the communication nodes are updated by the accessed IPv6 addresses; the accessibility from blocks directly to the communication nodes is inspected by using IPv6 addresses of the communication nodes; once the accessibility is validated, tunnel transmitted data blocks in a first IPv6 block are started to be transmitted from the moved nodes to the communication nodes; and the tunnel transmitted data blocks are directly transmitted from the communication nodes to the accessed IPv6 addresses of the moved nodes.
