A management server 10 includes a vSW usage management table 11 for storing an index for identifying an interface for each customer intranet 4, where the interface is used to connect a VM 23 and a PC5 in the customer intranet 4 connected via a router 3 and is being used. When the management server 10 is compatible with an IPv4 network and when receiving a connection request for a connection to the router 3 connected to the customer intranet 4, the management server specifies an identifier for identifying an interface that is not stored in the vSW usage management table 11, connects the router 3 and the VM 23 by using the interface indicated by the specified identifier. |
