Abstract
A transferring device (100A) acquires address information indicating a network address of an upper network (N0) and a host address of the transferring device. The transferring device generates a subnet address which is a network address of a lower network (N1) by replacing a lower bit portion in the network address indicated in the address information with the host address indicated in the address information. The transferring device selects a host address to be assigned to a terminal device (220A) from a host address range which is based on the subnet address, and provides for the terminal device, address information indicating the subnet address and the selected host address.
Claims9
A transferring device which is connected to an upper network and a lower network and transfers a packet, comprising:
- processing circuitry
- to acquire address information indicating a network address of the upper network and a host address of the transferring device in the upper network;
- and
- to generate a subnet address which is a network address of the lower network by replacing a lower bit portion in a bit string representing the network address indicated in the acquired address information with a bit string representing the host address indicated in the acquired address information.
