A network address assigning system includes sub-networks connected to each other, a network composed of the sub-networks connected to each other, an address server for managing network addresses of the sub-net-works, nodes for transmitting and receiving messages over the sub-networks, routing nodes for transmitting and receiving messages, for transferring messages over the sub-networks, and for managing addresses of the sub-networks, a change indicator for causing the address server to re-assign network addresses of the sub-networks and for causing the routing nodes to notify the address server of the network addresses of the routing nodes, storage for causing the address server to store address information, and a notifier for causing the address server to communicate with the routing nodes and to notify the routing nodes of network address information that has been newly registered/changed. |

DETAILED DESCRIPTION What is claimed is: 1.
A network address assigning system, comprising: a plurality of sub-networks directly connected to each other; a network composed of said plurality of sub-networks; an address server for managing a plurality of network addresses of said sub-networks; a plurality of nodes for transmitting and receiving messages over said sub-networks; a plurality of routing nodes each having a node function for transmitting and receiving a message, a router function for transferring a message over said sub-networks, and an address management function for managing the addresses of said sub-networks; change notification means for causing said address server to re-assign the network addresses of said sub-networks and said routing nodes to notify said address server of the network addresses of said routing nodes; storage means for causing said address server to store address information; and notification means for causing said address server to communicate with said routing nodes and to notify said routing nodes of newly registered/changed network address information.
2.
The network address assigning system as set forth in claim 1, wherein when the network address information is registered by said change notification means, said address server does not notify said routing nodes of the newly changed/registered network address information.
3.
The network address assigning system as set forth in claim 1, wherein said routing nodes each have: means for requesting data from said address server; and means for obtaining a current address information of said network.
4.
A network address assigning system as set forth in claim 1, wherein an IP (Internet Protocol) datagram is transferred corresponding to a network address assignment table physically stored by said address server and said sub-networks of said routing nodes.
5.
The network address assigning system as set forth in claim 2, wherein said routing nodes each have: means for requesting data from said address server; and means for obtaining a current address information of said network
