摘要：
A path-information obtaining unit obtains a piece of path information of a communication network by inquiring a port number of an Ethernet switch that transmits a MAC address of a request source of an IP address. An IP-address specifying unit specifies an IP address that corresponds to the piece of path information of the communication network by referring to an IP-address correspondence table, and distributes the specified IP address to the request source of an IP address.
