A home agent assigns disjoint ranges of port numbers to mobile nodes that share a global IP address. In response to a registration request message from a mobile node, the home agent transmits to the mobile node its assigned range of port numbers, as an extension to a registration reply message. The home agent maintains data records for the mobile nodes that have registered with it, wherein a data record for a mobile node includes its global IP address, its assigned range of port numbers, and its current address. When the home agent receives data packets destined for one of these registered mobile nodes, as determined from the destination address and destination port number specified in the data packets, the home agent forwards the data packets to the current address listed in the mobile node's data record.

Address management methods and apparatus are provided for a node serving as peer group leader for a peer group of nodes in one level of the hierarchy of a PNNI hierarchical network, whereby the peer group leader represents the peer group to one or more neighboring nodes in the next level up of the hierarchy. The peer group leader has a memory (2) for storing peer group topology data (4), comprising address data which is supplied to the peer group leader from nodes in the peer group and represents addresses for access by the network, and peer group leader topology data (5), comprising address data which is supplied to said neighboring nodes by the peer group leader and represents addresses accessible via the peer group. The address management method comprises: checking whether addresses represented by said address data are accessible via the peer group; notifying said neighboring nodes of changes in the accessibility of addresses so identified; and updating said peer group leader topology data (5) in accordance with said changes.

In an address management system, an interface ID can be handed over from one apparatus to another without losing the correspondence between the interface ID and a user. As a result, the interface ID can be used as a unique identifier for the user. Accordingly, an effective infrastructure for individualized services is achieved. The interface ID may be constant for one user even when an apparatus is replaced, and thus IPv6 communication can be used as a user-associated address in high availability services, such as telephone services. Furthermore, the interface ID can be returned and reused, and thus the interface ID can be efficiently used.
