ABSTRACT:
Provided are a system and method for deleting tunneling when a correspondent node is connected to a mobile node that has moved to a different network. The system includes a domain name service server, a mobile node that moves to a different network, a domain name dynamic updating server, and a correspondent node. The domain name service server manages domain names and address of a plurality of mobile nodes. Once the domain name dynamic update server receives a message including the created address by the mobile node, the domain name dynamic update server updates domain name and address of the mobile node that are registered in the domain name service server using the domain name and address contained in the received message. The correspondent node connects to the domain name service server, obtains the updated address of the mobile node, and transmits a packet to the mobile node using the obtained address.
