The invention relates to a method for connecting a mobile node (1) comprising a plurality of network connection interfaces (11a, 11b) to at least one network (3) using the mobile internet protocol with the following steps for the respective interfaces (11a, 11b): -the mobile node (1) retrieves a local IP address (CoAa, CoAb) and at least one DNS server (5, 5a, 5b) address using DHCP on the interface (11a, 11b), -the mobile node (1) stores in a list the at least one returned DNS server (5, 5a, 5b) address, -the mobile node (1) queries the at least one DNS server (5, 5a, 5b) which has its address stored in the list for home agent service and receives either a“service not supported”failure notification or the address of at least one home agent (9a, 9b) reachable on the interface (11a, 11b),—the mobile node (1) stores in the list the results of the query, either“service not available”or the home agent (9a, 9b) addresses returned for the respective DNS Servers (5, 5a, 5b) inquired, -the mobile node (1) obtains a home address (Ho Aa, Ho Ab) on the interface, -the mobile node (1) attempts to perform a binding update for care-of-address (Co Aa, Co Ab) and home address (HoAa, HoAb) towards the at least one home agent (9a, 9b) address stored in the previous list and updates its stored list accordingly with respective binding success or binding failure notifications, in case of success, the mobile node (1) records on the list a fully qualified domain name associated to the interface (11a, 11b). The invention also relates to the associated mobile node and DHCP unit. |
