Disclosed is a technique in which, when respective addresses of multiple interfaces of a mobile node are registered with a mobile management device, a delay in transmission of packets destined to addresses other than the source address of a bulk registration message is prevented. According to the technique, an MN 100 uses each of addresses associated with IFs 1000 and 1001 as a source address, respectively, to send a HA 101 an individual registration BU message S30, S31 for registering the source address individually. When receiving the individual registration BU message S30, S31, the HA 101 registers the source address as having been verified through ingress filtering of a foreign network domain 11, and sends a BA message S32, S33 to authorize bulk registration for updating the respective addresses in bulk.
